Title: Canon 1000d / Rebel XS
Post by: coutts on August 14, 2012, 02:41:27 PM
Any developers have this camera? With the 5dc and 40d being worked on, it should be easy to port the 1000d to ML as well now. The 1000d has live view, so it should be possible to capture video with it. 1000d shares the same low quality screen as the 5dc so I bet all of the vram stuff is the same.

Initial porting is already done by me. Look at this project here to get started, it boots the main firmware and sets the bootflag. Look at the 5dc entry.S / init.c to get an idea of where to start for the 1000d and ML.

https://bitbucket.org/coutts/1000d_dev

The entry.S of the 5dc can be seen here. As you can see it's very similar to the 1000d one I already wrote above:
https://bitbucket.org/hudson/magic-lantern/src/bbaee3c6d8d0/platform/5DC.111/entry.S

Only thing that will need fixed up is the call to where it sets up one of the main heaps. We need to shrink the heap and make room for ML to be copied there, and then link to this spot. It is not safe to link to 0x800000 from what everybody says (though I don't yet understand entirely why).

I have not worked on it in a while (no longer have access to a 1000d), but it is all set for someone to take over. Maybe someone has a 1000d to send to me?

Video mode with the 1000D?
Isn't it a Digic III model?
Digic III shouldn't be capable of encoding videos, right?

no, but we should be able to dump the live view buffer ;)

no, but we should be able to dump the live view buffer ;)
As for 40D then.
That will result in HUGE videoclips at less than 15 fps, right?
Like that third party application that dumped the frames from LV and saving them as avi.

Coutts,
I started thinking about making the 40D port when I saw your port of 1000D

I think live view updates at 30fps so it will probably be that. We need to speak to Alex about this, I only know it is possible. He knows how to implement it ;)

Coutts, could you please teach me how to use your SW?
How do I install and use it?
I have a Canon XS (AKA 1000D).

Seems like Coutts was very close to getting this ported over. Its not just going to die now is it? Anyone willing to take over?

To continue this work we have to own a camera.
If you have one of these cameras and have technical expertise, can make a contribution continuing the work begun by Coutts.

I own a 1000D and i'm a developer, mainly on C# but I'll give it a try... what work has already been done?
The features I would like to see on 1000D are the focus trap, time laps("Intervalometer ")

those seem very possible! To get started, look here:
http://magiclantern.wikia.com/wiki/Developing_info

The magic lantern repo can be found here:
www.bitbucket.org/hudson/magic-lantern

Follow the 5dc and 40d ports, as they are the only VxWorks cameras supported. I did some testing with the 1000d here, you can use it for the bootcode found in entry.s. The code here will boot the firmware and start a user task so it's a great starting point.
www.bitbucket.org/coutts/1000d_dev/src

jxlpto and myself are probably the best to talk to for porting VxWorks, so feel free to pm us with any questions.


good luck :D

I'm really hoping to get some help with my canon 1000d.  I bought a 1000d used and it came in Factory Service Mode.
When I connect it to a usb port it comes up as "DCP CONNECT" and the drivers won't recognize it because its not in PTP mode.
The bottom item under the first menu list is "Factory  Menu"
Anyone know how to get the 1000d out of Factory Service Mode?  Can Magic Lantern software be of any help here?

How is the development unfolding? If someone can walk me through testing it, I am happy to try on my 1000D. I am mostly using it for HDR bracketing. Is this functional at all for this model yet?

Can I download the 'repository' zip file and install it on my 1000d?
I just want intervalometer feature.

Hello,
I heard of Magic Lantern and I decided to install it on my camera, but I have a Canon EOS 1000D, so I found this thread.

I am willing to help with the development of this port. I'm an expert python programmer but I'm a beginner with C. I have already written working programs in C (mostly Arduino sketches) but I still consider myself a beginner.
That being said, I'm going to read how the boot process works on vxWorks and Magic Lantern.
I would mostly use it to record time lapse without using a computer, I'm not looking for too many features.

Is there anyone that is willing to chat with me on IRC about this? My timezone is GMT+1.

Hi, I own a D1000, what is the current status of magic lantern for  this Camera ?
If the port is not done yet, is there some help I could provide ?
[ I am a professional embedded C developer, with+20 years experience]
What's blocking ?
Title: Re: Canon 1000d / Rebel XS
Post by: nikfreak on November 29, 2015, 01:42:58 PM
Nothing's blocking it. Taking a look at the successor - the 1100D - I would say: grab yourself some updated and more capable cam. "Embedded C developer" sounds cool. Help is always welcome.

Post by: Walter Schulz on November 29, 2015, 02:10:19 PM
1000D is indeed a bit old and doesn't work with DRYOS (introduced about 2007) but VxWorks. Call it a lonely place even in not-so-crowded devland. If you insist working on it you may want to take a look over there: http://www.magiclantern.fm/forum/index.php?topic=991.msg157850#msg157850 where user gph reanimated 5Dc (VxWorks, too) development. Coutts seems to be out of town for some months. You may try to contact him anyway sending a PM.

Any news on this. I'm not developer but I own a 1000d, so if I can be of any help testing something just tell me. I'm mostly interested in the bracketing stuff
Title: Porting ML to 1000D (AKA Compiling for 1000D/XS)
Post by: shmadul on November 30, 2016, 01:56:51 PM
So ive been trying to compile the build from this forum here
https://www.magiclantern.fm/forum/index.php?topic=17991.0
and have had no luck, i keep getting bunch of errors, if its possible
for someone who already has the tools to compile it and could compile
and re-upload it for me that would be amazing. I just cant seem to do
it my self.......

Thanks,
Mason Dulemba

Post by: Levas on November 30, 2016, 04:54:05 PM
Unfortunately there is not much to compile, the files which were made by Coutts are only capable of letting the blue led on the camera burn.
So these files are only a very small beginning for porting the 1000d and no where near a working magic lantern build.

I'm not sure what the next step would be, probably a firmware dump with the use of the blue led?
After that, all sorts of addresses need to be found in the rom dump for use in the magic lantern software.

Post by: Walter Schulz on November 30, 2016, 08:02:38 PM
No contradiction.
You read something you want to read. He simply wrote "get it running" and "it" is not ML with the functions you get with cams running ML nightly build.
Title: Re: Compiling for 1000D/XS
Post by: SysCall on November 30, 2016, 11:26:16 PM
I already explained shmadul it is not a final built or even close to it.

Since he is new (like me), it is a little bit confusing to get into the development.

It is hard to start from scratch and figured out everything, especially since the forum is big and the information are spread all over the forum (use search engine, I know, but still confusing).

@shmadul
If you have troubles to compile, you should have posted in the other thread instead of opening a new one, then I would noticed it earlier.
Unfortunately, I do not look that much often in the forum, since I have a full time job and I spend the rest of time mostly shooting :D

If you still interested or anybody else, here is the compiled version:

Status: Awesome blue LED blinking
https://1drv.ms/f/s!AsC1K_kH7N9pbYhpDPUbSuC8Iss (https://1drv.ms/f/s!AsC1K_kH7N9pbYhpDPUbSuC8Iss)

Instruction:
1. Format your SD card in the camera
2. Extract the rar and copy and paste in the root of the SD card
3. Go to Menu -> Firmware update -> start it
4. Profit -> blue LED should blink and turn off after while

@Levas
Thank you for another bit of useful information ;-), I was searching for the next step.
In general I was looking for a development process to port magic lantern to different cameras, but didn't know where to start.

Maybe we can manage to organize a Canon 1000D team or something.


Cheers

@syscall That would be great, as i desperately need this for a class project..... Im a quick learner, i know a bit of everything when it comes to programming languages, C++, Java, JS, html, python, ive done some exploitation work for other platforms such as OS X and iOS, but from what im picking up as i go this seems a bit easier...

Just have a few Questions for You or anyone really....
1. How do i go about changing what is executed (iE: Currently the blinking lights script runs) but what file(s) control that,
Dont want to mess with any of the exploit work, because that seems to be working fine..
2. What all needs to be done scripting wise to tell it to hijack the canon Ui and boot ML ?

Thats it for now :)
Thanks,
Mason Dulemba
Title: Re: Compiling for 1000D/XS
Post by: shmadul on December 01, 2016, 07:44:12 PM
So i've Read this post   
   "A. Bootloader starts up and checks card and boot settings
    B. It will find the Boot Flag set so it will check for a bootable card
    C. Once found it will load canon firmware and then ML's autoexec.bin"
and have a guess as to how this works
1. The 1000D.fir file contains the exploit and sets the Boot Flag which then looks for the autoexec.bin file Correct ?
2. The autoexec.bin file contains the script to make the blue light blink
3. And normaly there is a ML folder for all the ML menus and stuff, does this need to be custom made specifically for the Eos XS ? Or are all ML folders the same for all builds?

Thanks,
Mason Dulemba

@Syscal and @shmadul
Great, so we got three people who are willing to put some effort in the 1000d.

Alex is willing to help us if we can get some stuff done
http://www.magiclantern.fm/forum/index.php?topic=14732.msg172723#msg172723 (http://www.magiclantern.fm/forum/index.php?topic=14732.msg172723#msg172723)
I've send him a message a few weeks ago that I got the blue led blinking, now he asks for making the blue and the red led to blink
Probably to prove some sort of understanding of the written code.
But I got stuck letting the blue and red blink, here's where you guys probably could help.

As far as I understand, the program that runs on 1000d exists from these files.
main.c
main.h
Entry.s
Entry_subs.s

All these files can be viewed in a normal text editor and edited and compiled for testing.
Most stuff is done in the main.c
The entry.s contains arm code, see this link:
http://magiclantern.wikia.com/wiki/ASM_introduction (http://magiclantern.wikia.com/wiki/ASM_introduction)
The entry_subs.s contains addresses where commands are called in the 1000 firmware I think.

So does one of you know how to change the above files to get both the red and blue led blinking ?

   {
      LEDBLUE = LEDON;
                LEDRED = LEDON;
      msleep(500);
      LEDBLUE = LEDOFF;
                LEDRED = LEDOFF;
      msleep(500);
   }

Also, Could http://www.magiclantern.fm/forum/index.php?topic=14732.0 help us, Who wants to set up a github project for our team ??

Just a Note, Use Firmware Version 1.0.7 because anything Lower doesnt seem to work with anything that has been developed so far
Title: Re: Compiling for 1000D/XS
Post by: SysCall on December 02, 2016, 10:24:31 PM
Sounds good guys.

Can you guys also post when something is working, how you do it, especially if it was mentioned in the previous post as issue or problem?

E.g. shmadul, you mentioned you couldn't get it compiling and suddenly it works, but you did not mentioned the solution.

So, how you resolved the problem?

The answer would not only help other if they running into the same problem, but also document the status of the current work.


I'm currently trying to clean some code and make a readme.txt, it needs some time.

I will post it once it is done.

cheers

-----------------------------
Baseline: 0
-----------------------------

Let start fresh.

A: Set up a workspace
-----------------------------

1. Setup Magic Lantern for development, I used this instruction
http://www.magiclantern.fm/forum/index.php?topic=16012.0 (http://www.magiclantern.fm/forum/index.php?topic=16012.0)

My setup:
Thinkpad T420 with hackintosh, El Capitan 10.11.4

Make sure that you can compile one of the current working projects 5D3, 6D or etc.

2. Download Canon 1000d project and put it in the platform folder of magic lantern.
https://bitbucket.org/coutts/1000d_dev/src (https://bitbucket.org/coutts/1000d_dev/src)

3. We have to fix the makefile and update it to a newer version of the compiler.

Go to:
magic-lantern/platform/coutts-1000d_dev-a7835d17602f/

Open the makefile with a text editor and replace the following code

CC=arm-none-eabi-gcc
AS=arm-none-eabi-as
OBJCOPY=arm-none-eabi-objcopy

with

CC=~/gcc-arm-none-eabi-4_8-2013q4/bin/arm-none-eabi-gcc
AS=~/gcc-arm-none-eabi-4_8-2013q4/bin/arm-none-eabi-as
OBJCOPY=~/gcc-arm-none-eabi-4_8-2013q4/bin/arm-none-eabi-objcopy

Don't forget to save it!

Source:
https://www.magiclantern.fm/forum/index.php?topic=17991.0 (https://www.magiclantern.fm/forum/index.php?topic=17991.0)

4. Now try to compile it, when everything works, you should end up with a new "AUTOEXEC.BIN"

Open a terminal and type:
make clean
make

"make clean" - removed compiled files
"make"          - compiles the project

5. Generate a firmware for the Canon 1000d.

We have to compile a .fir file to be able to boot our own code.
Note: AUTOEXEC.BIN has to be generated first, since it is the input for the .fir

In terminal type:
perl assemble_fw

A file called 1000d.fir should be now generated.

6. Put it on a SD card
Take an empty SD card and format it in the camera.
Copy the following files to SD card:

1000d.fir
AUTOEXEC.BIN

7. Try it in the camera.
Go to Menu and then to Firmware update section.
Select firmware to get to firmware update screen and press ok.


B: LED blinking example
------------------------------

I have take a look in the "engelmarkus_examples/2_1000D LED-Dumper" folder and used it as base for this example.

Download the example from here (led_blinking.zip):
https://1drv.ms/f/s!AsC1K_kH7N9pbYhpDPUbSuC8Iss (https://1drv.ms/f/s!AsC1K_kH7N9pbYhpDPUbSuC8Iss)

What is it:    
It lets both LEDs (blue and red) blinking in sync.
It is intended to have something to play with.
You guys can modified the time of blinking in the main.c and now the code should behave like it should.

What is it not:   
A full working version of Magic Lantern.

Instruction:
The example comes with everything pre-compiled.
You can extract the files and follow step 6 from the instruction of section A.
Or you can compile it by yourself.

What was done:
- I took some functions defined in the "2_1000D LED-Dumper" and put them in the
   basic_functions.h
   basic_functions.c
- Some cleanups and documentation of the code.
- The firmware generation was base on e6kr5106, I updated the firmware generation to e6kr5107 (just used the script and files from latest release).
- All basic_functions functions are binded in the main.c now.
- Adapted it for the compilation.

Note:
This version does not contains the sub routines, which was defined in the latest release by Coutts in the entry.S or entry_subs.S files.
I guess he tried to adapt the boot routine from the 450? to the 1000d, but I could not get the LED blinking working on the latest version.


If you guys find some errors in the code let me know, I will update the example.
Hope this help some people to get into development for the Canon 1000D.


Have fun, I'm out photographing.

Don't like typing each time in the terminal the three commands?

Code: [Select]
make clean
make
perl assemble_fw

Me too, lets change that and create a bash script.

Create a new file, add the following "code" and save it as run.sh (compilation.sh or something else as you like).

Works on Mac and should also work in Linux.

Code: [Select]

#!/bin/bash

echo "Compiling starting ..."

echo "Removed previous compiled files ..."
make clean

echo "Compile the project ..."
make

echo "Generate the new firmware ..."
perl assemble_fw

echo "Compilation finished."


Put it in your project folder.

Now, in terminal only execute the script with:

Code: [Select]
./run.sh

@syscall about the script you made, Very similiar idea to one i had, heres a script that builds it, assembles it moves it over to the sd card, renames the sd card to EOS_DIGITAL, and then makes the card bootable, just by typing updateml in terminal :) Just Edit it to suit your needs and replace the directories where appropriate :) FOR OSX ONLY !!
Download makebootable.sh here https://mega.nz/#!MlZh1JzJ!M3hLfDDJ_zjI85QdNKyTUmdMnJri_EZJJmmrMmxe-KA

@Levas

Those are not "errors" they are warnings and as long as you end up with an AUTOEXEC.BIN, that means your compilation was successful.


Quote
I only get a blue burning led on the 1000d, no more blinking...

Exactly, some clarification here.

In my explanation / little tut (Section A) above I explained the work flow to get an AUTOEXEC.BIN and a firmware file 1000.fir.

If you do so, it will re-compile the current code in coutts folder.

The latest code in coutts folder and the pre-compiled AUTOEXEC.BIN and 1000.fir which comes with it are not the same!

He changed the code after he generated the AUTOEXEC.BIN and 1000.fir files.

That means, if you compile the source code new, you will always end up with a black screen on your camera and a glowing blue LED.

I don't know why yet, but it does not matter what I change in the main.c, I always end up with a blue LED glowing.
 


That is why I included an example in my Tut (section B), which contains a working version of blinking of both LEDs (with a camera black screen).

So if you download my example (B: LED blinking example) and re-compile it and put it on your camera, you should end up with two LEDs blinking in sync.

The files led_blinking.zip, comes with all source code and pre-compiled files, use this as project folder and compile inside this folder.

When you change e. g. duration or order of the blinking in the main.c and re-compile it you should be able to see the result on the camera.

And take a look into the source files, since I try to explain what each code line does.

Thanks Syscall, and sorry for the bad reading on my part  :P , the working files were already there in you earlier post.

So now we've got a 1000d with flashing LED's. Perfect decoration for under the tree this christmass season  ;D

So I've downloaded your zip file and compiled it myself, there where some files missing to do that, which I took from Coutts files.
I want to start with a clean directory of files, I've downloaded your zipfile and added these files, are they all necessary ?

assemble.wf
crc16.c
crc16.h
e6kr5107.fir_0_header.bin
e6kr5107.fir_1_flasher.bin
entry.S
link.script

Something went wrong here, all files are in the zip

@levas, Nice Work  :D, Ive Heard the 450D is almost the same as the 1000D so maybe we could either see if we can apply the code to our port or see if we could get one of the guys working on the 450D port to help us get ML running, We already have the FW exploited and booting custom code, we just need to port the ML GUI and stuff

-----------------------------
Documentation
-----------------------------

Before we can port magic lantern to this camera, we have to understand what magic lantern is doing in the first place.

I will try to explain what my understanding of how magic lantern works so far is.

If some information are wrong or missing, please let me know.


A. Boot-up process
---------------------

Cases:

1. Turn camera on (normal):
The camera will boot up the firmware, normal camera operation.

2. Update the camera (normal):
With the original canon.fir on the SD card.

In the camera menu -> firmware update execution.

The new firmware will written into the internal flash.

This is the typical process for any firmware updates, not only on cameras.

After the firmware update finished, the camera reboots and the camera operates as usual.


3. Update with custom generated .fir file

With the custom .fir and AUTOEXEC.BIN on the SD card.

In the camera menu -> firmware update execution.

The custom firmware .fir on the SD card sets a boot-flag, which allows us to load the AUTOEXEC.BIN from the SD card.

The camera restart, now the camera is in normal operation + custom magic lantern code running in parallel.

Since the boot-flag is set, the camera will load the AUTOEXEC.BIN automatically each time the camera is started,

when turn on and off with camera switchI guess.


Comments on case 3:

This seems the normal operating process of magic lantern on most of the implementation so far.

Coutts explained here a little bit deeper:
https://www.magiclantern.fm/forum/index.php?topic=1452.0 (https://www.magiclantern.fm/forum/index.php?topic=1452.0)

And here in the wiki:
http://magiclantern.wikia.com/wiki/Packing_FIR_Files (http://magiclantern.wikia.com/wiki/Packing_FIR_Files)


B. Current development
---------------------------

Now that is interesting, because in my example "led_blinking.zip" I don't remember setting any bootflags.

So why does it work anyway?

The code for the modification of the boot process is usually defined in:

entry.S


Well looking into the entry.S shows:

Code: [Select]

.text
.org 0
.globl _start, start

start:
_start:
sysInit:
B main

.align 2
fin:



And the there is no entry_subs.S file so far in "led_blinking.zip" release.

So the question would be, does it also work without the AUTOEXEC.BIN on the SD card?

After a quick test with only the 1000d.fir on the SD card.

The answer is, yes it does. But why?


Well, thinking about it, what is the 1000d.fir?

It is base on the AUTOEXEC.BIN, which is again base on our code in the main.c.

Compilation order:  brain -> main.c -> AUTOEXEC.BIN -> 1000d.fir

Simple speaking, the 1000d.fir is like an .exe in windows with our code.

Each time we execute the 1000d.fir through the firmware update menu, our code will be executed.


That means:

1. The .fir file and AUTOEXEC.BIN, both can have the same code.

2. The .fir file can be executed standalone without the AUTOEXEC.BIN.

3. Each time we turn the camera off and on, we have to start the firmware update process again to load our code.

4. The AUTOEXEC.BIN can only be executed if the bootflag is set.

   And setting the bootflag can be done with the .fir file, since we know how to sign it and the camera can read and executed it.
 

Now, I just need some confirmation to back up my theory.

After thinking a while, I remember somebody gave a talk about magic lantern.

A quick google search and here we go:

Presentation:
https://events.ccc.de/congress/2013/Fahrplan/system/attachments/2246/original/Magic_Lantern_30C3.pdf (https://events.ccc.de/congress/2013/Fahrplan/system/attachments/2246/original/Magic_Lantern_30C3.pdf)

Video:
https://media.ccc.de/v/30C3_-_5554_-_en_-_saal_6_-_201312281400_-_magic_lantern_-_michael_zoller (https://media.ccc.de/v/30C3_-_5554_-_en_-_saal_6_-_201312281400_-_magic_lantern_-_michael_zoller)


From slide 23 of the presentation:

8.2 How is ML being executed?

Method 1: Firmware update
- We forge a firmware update file (.fir) with Magic Lantern as payload
   - Contains no flash data
   - Flash loaders in .fir are replaced with our code
   - Checksums and hashes need recalculation

- User runs firmware update from original firmware menu

- Firmware restarts into boot loader

- Bootloader loads .fir into RAM and executes it

- Magic Lantern takes over control of the system and boots original firmware


Method 2: Autoboot

- Using .fir we set a flag in flash called "BOOTDISK"

- Bootloader checks for "AUTOEXEC.BIN" on CF/SD

- If found, it gets loaded and executed without checks

- Magic Lantern takes over control of the system and boots original firmware

----------------------------

Now, looking at Coutts latest release, we do have functions to set and de-assert the bootflag.

The functions to enable and disable of the boot-flag is defined in:
entry_subs.S

NSTUB(EnableBootDisk, 0xFFD21248)
NSTUB(DisableBootDisk, 0xFFD21260)


C. Development outlook
----------------------------

Highest priority:

- Currently the screen is black during the code execution (led_blinking.zip).

- We have to find out, how to load the original firmware to get into the normal operation mode where we can see the camera menu.

- After that we can try to get the magic lantern menu showing up on the screen and porting all functions to get magic lantern works correctly.


Low priority: Highest priority:

Figured out how to set the bootflag correctly to auto load the AUTOEXEC.BIN.

If it was that simple, why Coutts comment the code section out with the functions call in his latest release?

Translating his comments of the latest release, he had troubles to get it working correctly.

@shmadul, @levas

Thanks guys, but I have read a lot so far and the canon 1000d is often mentioned to be similar to this and that camera.

Sometime it is similar to 400 plus and sometimes you should use the 5Dc for the port and then maybe the 450D.


Some example, by Coutts himself:

https://chdk.setepontos.com/index.php?topic=6238.msg86614;topicseen#msg86614 (https://chdk.setepontos.com/index.php?topic=6238.msg86614;topicseen#msg86614)

https://www.magiclantern.fm/forum/index.php?topic=2054.0 (https://www.magiclantern.fm/forum/index.php?topic=2054.0)


We have to clarify first, which one makes sense and worth the effort.
Title: Re: Compiling for 1000D/XS
Post by: a1ex on December 05, 2016, 08:20:21 PM
A little more stuff:

There are two parts of the firmware: the bootloader and the main firmware.

The bootloader can:
- perform some low-level configuration (e.g. the MPU*) registers, which can give hints about the memory map)
- load FIR files
- load AUTOEXEC.BIN (if the boot flag is enabled)
- show a small diagnostic menu (aka FROMUTILITY)
- jump to main firmware

*) MPU = memory protection unit (see the ARM docs). Not to be confused with what Canon calls MPU (http://www.magiclantern.fm/forum/index.php?topic=17596.0) (a microcontroller).

In DIGIC 5 and earlier, the bootloader starts at 0xFFFF0000 (aka HIVECS or high exception vectors in ARM docs).

The two parts are pretty much independent: once in bootloader context, your program can call other bootloader routines, and once in main firmware, you can call main firmware routines. If you mix them, it won't work. Exception: some very simple routines that don't use any state (such as strlen).

ML runs alongside main firmware. In order to do that, it has to modify the startup routine, reserve some memory (so Canon firmware won't overwrite it) and launch one user task. Once you did that, our code is running as a regular task on Canon's operating system (be it DryOS or VxWorks). From here, it can launch other tasks, call file I/O routines or whatever.

For trying out things, you can compile the "recovery" branch from ML, from platform/portable.000. This will give you a portable autoexec.bin that runs on all cameras (and also in QEMU), and has display access (from the bootloader context). Of course, this autoexec can be signed as FIR and loaded without requiring a boot flag.

The boot flag can be enabled from both bootloader context (as done in the old 5D) or from main firmware. EnableBootDisk only works from main firmware, but usually there is an equivalent bootloader routine, found in the FROMUTIL menu.

If you want to convert 450D port, the first thing you should do is set bootflag and check it with help of AUTOEXEC.BIN from "display test" topic. It's because all VxWorks ports use AUTOEXEC.BIN startup method.

Then you should find addresses of functions for 1000D in your firmware dump and change them in "\platform\450D.110\stubs.S". It can take many days or weeks.

After this you should edit cache related stuff in "\platform\450D.110\init.c", and edit another files in "\platform\450D.110\" and in "\src"

Great to see Alex arrive in this post  :D

Indeed the 1000d and 450d have a lot in common, but I'm not sure if that helps a lot with porting ML.
Since we know that even different firmwares need different ports, like in the 5d3.

It seems that most of the work is in finding the right addresses in the firmware.
But for that we need to have a firmware dump.

Which, as far as I know, isn't available for the 1000d ?
So is the first thing to do now, get a firmware dump ?
And how, can we write a program to make the 1000d do a firmware dump on the SD card.
Or can we just use the FIR file from the 1000d 1.0.7 update from the Canon site ?

And Alex, are there advantages to make it run in QEMU, or can we just try our stuff out on our real alive and kicking 1000d's, how big is the risk of bricking them ?

I'm sorry Ant123, I don't understand.


Btw, it looks like I got autoboot working too, at least when I change the AUTOEXEC.BIN I see that it is automatically executed.

Also after switching the camera off and on I see my code running, I also get into main Canon menu. So I guess the firmware just boot normally and the code runs in parallel.

I want to confirm hat as you said by using the display test.

But I can confirm, I can change the AUTOEXEC.BIN only and it will executed after each restart:
- removed battery and put it back
- switch the camera off and on

Maybe I should make a video.

Read that topic (http://www.magiclantern.fm/forum/index.php?topic=14732.0) from the begining to the end again.

If BOOTFLAG is set you will see "BOOT=-1" ( -1 == 0xFFFFFFFF)

Start simple :)


What I did was, in Coutts latest release, I just comment out the following code section.

Code: [Select]
// EnableBootDisk() 
Funktion f = 0xFFD21248;
f();

After that, I made the SD card bootable by executing in terminal:

Code: [Select]
sudo ./make_bootable.sh

After executing .fir the first time, I don't need it anymore and the camera loads the AUTOEXEC.BIN automatically.

I was working only with VxWorks ML ports (40D and 5DC ) to get ML on 450D with minimum functionality .

I know it is not ML, I was using it as base to get into ML development.

I totally new to this.

Since I couldn't find a description about the workflow on how to port ML to a camera, I tried to understand everything first.

If you look at the date of this thread, you would realize that we just started.

It helps that we just have a basic project like the one from coutts to play with.

Also it is the only project of the canon 1000D that I know or could find.

How can I start porting something if I don't understand the basics?

Yesterday we didn't have a boot flag that was set.

Good work by the way, Syscall.
You now a lot more about the technical side then I do.

So you set the bootflag, can you share the FIR file you did it with?
This way we could just run autoexec.bin at startup, no more firmware updates.
I'm just new to the magic lantern source files and finding my way to find addresses in firmware.
So I hope I can help when you're a little further in finding your way in magic lantern.

@shmadul
You're right.
Normally to run ML you don't need the fir file.
Once you enabled the bootflag, ML runs with autoexec bin file and the ML files in the ML directory on your SD card

Post by: shmadul on December 06, 2016, 10:09:03 PM
any ideas ? I found this on the web :)
" I finally figured out why my code did not work with autoboot before, one tweak should fix things:
in link.script, change:
Quote
first 0x800120 :
to:
Quote
first 0x7F0000 :

Also, add this function to main.c:
Quote
void COPY() {
        int i;
       
        long *from = (long*) 0x800000;
        long *to   = (long*) 0x7F0000;
       
        for (i = 0; i < 0x100000; i++) {
                to = from;
        }
}

and in entry.S modify it to look like this(I have bolded the one addition):
Quote
.text
.org 0
.globl _start, start

start:
_start:
        BL    COPY
        BL    my_LedBlueOn
        B      loc_FF810054


The problem was that before, the link script said to link the code to 0x800120, but the makefile linked it to 0x7F0000. This doesn't work because the code is actually loaded to 0x800000 by the bootloader. We first need to copy our code from 0x800000 to 0x7F0000 (a safe spot in memory, 0x800000 will be overwritten by the canon firmware during the boot process). Then our code will be executed from there.

I'm out of the game.

I just successfully bricked my camera.

I managed to enable and disable the boot flag a few times in row without any issues and then ...

Now the boot flag says BOOT=-348549156

Camera can still read the autoexec.bin after removing the battery and put it back.

Black screen when no SD card or none bootable SD card is inserted.

Re: How do disable Bootdisk flag on a 5D Mk III
« Reply #36 on: September 24, 2013, 04:12:57 PM »
Hi all.
First of all, Thank you all developer.

I'm thinking about this problem. And yesterday, I built magiclantern compiling system.
I modified latest source code, and made special autoexec.bin.
This modification is calling "Disalbebootdisk" at auto save toggle.
I was dumping address at before and after modification, call"Disablebootdisk"
I checked these dumping result. Offset+4 address from 0xF8000000 is changing from 0xFFFFFFFF
to 0x00000000. This is clearing boot flag. But, I found some different point at other address. woo... :'(
May be, some developer is thinking that this result is occerd a bad influence on camera function.

After disable boot flag, I updated canon firm V1.2.1.
At present, I can't find a problem.
System boot time become so fast. and Eye-fi card is enable.

void
config_autosave_toggle(void* priv)
{
#if 0
    config_flag_file_setting_save(CONFIG_AUTOSAVE_FLAG_FILE, !!config_autosave);
    msleep(50);
    config_autosave = !config_flag_file_setting_load(CONFIG_AUTOSAVE_FLAG_FILE);
#endif
    bmp_printf(FONT_LARGE, 50, 50, "disable flag start");
    call( "DisableBootDisk" );

    bmp_printf(FONT_LARGE, 50, 50, "disable flag end");
}

@ a1ex

Thank you very much for your help.


Here is my observation so far if someone is interested.
----------------------------------------------------------------------------------------------

What happened:
After enabling and disabling the boot flag several times the camera stops booting.

Why would I enable and disable multi times?
I want to make sure that it works stable, before posting it.

Camera still load autoexec.bin if the SD card was prepared for autoboot.

Observation:
Camera stays black after turning on, regardless of normal SD card or if it was made bootable.
Camera still functioning, if looking through the view finder, settings like aperture or exposure time can still be changed.
Taking picture is not possible only focus when pressing the shutter button.

Test 1:
-------
Putting display test (Magic Lantern Rescue) autoexec.bin on a bootable SD card shows:

Boot flags:
FIR=1610949440
BOOT=-348549156
RAM=-304267216
UPD=-1

Test 2:
-------
Putting (RAMEXEC fix) autoexec.bin from a1ex on the bootable SD card:

Camera boots up into canon menu, camera operates normal, taking pictures also possible now.
Magic Lantern Rescue still shows the same values.
Then did "clear setting" in canons menu, no changes.

Test 3:
-------
Same configuration as Test 2 plus canon original firmware update (e6kr5107.fir):

After updating the firmware, the FIR was reseted to zero. Rest still the same.

Boot flags:
FIR=0
BOOT=-348549156
RAM=-304267216
UPD=-1


Test 4:
-------
Same configuration as Test 2, now with the .fir that I compiled myself and was using to disable the boot flag.
After booting up and executed the .fir in menu update, camera boots up normal.

Looking again in the Magic Lantern Rescue shows:

Boot flags:
FIR=0
BOOT=0
RAM=-304267216
UPD=-1


The only thing that is not reseted is the RAM, which is still RAM=-304267216 instead of RAM=-1.

But now the camera still need a bootable SD card and the RAMEXEC fix autoexec.bin (or valid autoexec.bin) to boot into orignal firmware. When booting without SD card, the camera shows black screen, but still focus if press shutter button.

The interesting part is, even the Magic Lantern Rescue menu shows BOOT=0, the camera still auto execute the autoexec.bin.

Also, usually if the camera has the latest update it says "latest firmware installed" or something similar and
refuse a firmware update, but I'm still able to update the original firmware update as many time as I want.

1. Making dumps of RAM and ROM of the camera
2. Map all the magic lantern functions to the addresses located in the RAM

Magic Lantern use most of the standard functions of the original firmware which is loaded into the RAM after the boot up.
What you have to do is to "hook" (I think that is the term for it) those functions in the stubs.S file.

BTW, Ant123 gave you already the answer.

Quote
If you want to convert 450D port, the first thing you should do is set bootflag and check it with help of AUTOEXEC.BIN from "display test" topic. It's because all VxWorks ports use AUTOEXEC.BIN startup method.

Then you should find addresses of functions for 1000D in your firmware dump and change them in "\platform\450D.110\stubs.S". It can take many days or weeks.

After this you should edit cache related stuff in "\platform\450D.110\init.c", and edit another files in "\platform\450D.110\" and in "\src"

The interesting part is, even the Magic Lantern Rescue menu shows BOOT=0, the camera still auto execute the autoexec.bin.

That's because both autoexec.bin and ramexec are handled from the same routine, which happens to check the card bootflags first. You were quite lucky with this one; by disabling the boot flag, you risked removing the ability to run user code on the camera (other than ramexec, which simply jumps to 0x800000 without initializing that memory area; it assumes something was already loaded there somehow).

I wouldn't advise messing with boot flags just to see what happens, as you may get a configuration that no longer boots at all. In particular, on DIGIC 5, such configuration is very easy to get by changing the value at 0xF8000024 (even by mistake). Recovery from this would only be possible with hardware changes (lookup Ant123's posts on CHDK forum for an example).

Do you still have the FIR file that bricked the camera? It would be helpful to understand what happened.

You should not reinvent the wheel. Use modified common installer for VxWorks cameras (https://bitbucket.org/hudson/magic-lantern/src/18ac6b0f992918c7ba6dd282c3e74ca42574561c/installer/450D.110/bootdisk.c?at=vxworks).

You can also easily modify it to repair you camera.

No, that was not my intention, but maybe I should test it by myself before post it for others. At least I felt the needed to do some kind of verification. I always went with the mindset that I could damage my camera for this project. At least if I damage it myself, I can blame myself for it. Now, what if I just post the .fir and someone else brick their camera. Of course, even if state "use at your own risk", people would not be happy with it.

Especially if it is the only camera that they own:

Of course you can argue, this is the development section and not the release section.

Warning: Still under investigation, don't try anything described below if you don't want to damage your camera.

a1ex mentioned:

Quote
The boot flag can be enabled from both bootloader context (as done in the old 5D) or from main firmware.
EnableBootDisk only works from main firmware, but usually there is an equivalent bootloader routine, found in the FROMUTIL menu.

I tried with EnableBootDisk in the firmware.

In entry_stubs.S are the following function references defined.

Code: [Select]
NSTUB(EnableBootDisk, 0xFFD21248)
NSTUB(DisableBootDisk, 0xFFD21260)

Only, calling them in the main.c does not enable or disable the boot flag.

Coutts (original author) defined a pointer in the main.h

Code: [Select]
typedef void (*Funktion)();
and call it the main.c with the address of the EnableBootDisk.

Code: [Select]
// EnableBootDisk() 
Funktion f = 0xFFD21248;
f();
By doing this the boot flag gets enabled.

Calling this:
Code: [Select]
// DisableBootDisk()
/*  Funktion f = 0xFFD21260;
f();

will disable it again.

At least that is what I observed.


@Ant123

Just for my understanding.

The installer enables the boot flag from the bootloader context?

You also needed the address of the write and read functions.

Code: [Select]
     * 0xFFFF89F0 | start of write_bootflag in 5dc BL.
     * 0xFFFF8A94 | end of write_bootflag in 5dc BL.
     * 0xFFFF8AE0 | start of read_bootflag in 5dc BL.
     * 0xFFFF8B20 | end of read_bootflag in 5dc BL.

To find those addresses I have to do this:

Quote
   * I located these functions by hand using the 400d bootloader as a reference. I had
   * to write code to search the bootloader region (0xFFFF0000-0xFFFFFFFF) for signatures
   * of the read_bootflag and write_bootflag functions. It was a very long/tedious process
   * checking each address one at a time - blinking everything through the LEDs. These
   * routines are safe to run to the best of my knowledge, I have not had any issues yet.

Digging a little bit in this thread:
https://www.magiclantern.fm/forum/index.php?topic=1452.0

Coutts said:

Quote
If 40d is similar to the 5dc, then you won't be able to run any practical code from a FIR (including calling the EnableBootDisk function or booting the firmware/camera) so you will need
to write some code that scans the bootloader area (0xFFFF0000-0xFFFFFFFF) for function signatures to identify the read/write bootflag functions. This will allow you to set the camera's bootflag,
to boot an autoexec.bin file with a prepared card, and development takes off from there (you will be able to boot the firmware and do anything from autoexec). I created this bootdisk code from the 350d method, using the 400d bootloader to find the signatures I needed.

You can use this to write code to search for specific signatures of the read_bootflag and write_bootflag functions.
Some signatures would be instructions like:

    MOVEQ   R7, #0xF8000000

which is assembled and looks like this in memory:

    0x03A0733E

I'll just tell you the signatures to find.
First, for write_bootflag. Here is a small snippet from that function, the first 5 instructions:

    ROM:FFFF89F0                 STMFD   SP!, {R4-R8,LR}
    ROM:FFFF89F4                 MOV     R5, R1
    ROM:FFFF89F8                 MOV     R4, #0
    ROM:FFFF89FC                 CMP     R0, #0
    ROM:FFFF8A00                 MOVNE   R7, #0xF8000000

If you were scanning memory, these 5 instructions would look like this(starting at 0xFFFF89F0 on the left and ending on 0xFFFF8A00 on the right):

    0xE92D41F0 0xE1A05001 0xE3A04000 0xE3500000 0x13A0733E

So, look for the signature for the MOVNE R7, #0xF8000000 instruction, then once you find it, search backwards for the STMFD (push) instruction signature, and you will have located write_bootflag in the 40d bootloader. Chances are the functions will probably be identical, but take caution to verify at least 3 times that you have located the correct function and it seems the same / similar to the 5dc one (remember we are working blind here).


Now, read_bootflag. First 5 instructions look like:

    ROM:FFFF8AE0                 STR     LR, [SP,#var_4]!
    ROM:FFFF8AE4                 CMP     R0, #0
    ROM:FFFF8AE8                 MOVNE   R3, #0xF8000000
    ROM:FFFF8AEC                 ADDNE   R3, R3, #0x2000
    ROM:FFFF8AF0                 MOVNE   R2, #0x40

And in memory would look like this (same thing as before, starting at 0xFFFF8AE0 on left and ending at 0xFFFF8AF0 on the right):

    0xE52DE004 0xE3500000 0x3E33A013 0x12833A02 0x13A02040

Note: there isn't a STMFD (push) instruction in read_bootflag. The 400d bootloader is like this too, so chances are the 40d is as well.



Now there are a few things that I don't understand.

1.
Search for specific signatures of the read_bootflag and write_bootflag functions

According to the two sources I have to blink through the address range (0xFFFF0000-0xFFFFFFFF) and find the "signature".

Where I can find the asm signature?

Example:

Do I have to blink one address and then make a ROM dump?

Afterwards I would load the ROM.BIN in IDA and jump to the part where I did the blinking and check if I can see the signature?

Otherwise I don't know how he gets the assembly instructions:

Quote
    ROM:FFFF89F0                 STMFD   SP!, {R4-R8,LR}
    ROM:FFFF89F4                 MOV     R5, R1
    ROM:FFFF89F8                 MOV     R4, #0
    ROM:FFFF89FC                 CMP     R0, #0
    ROM:FFFF8A00                 MOVNE   R7, #0xF8000000

2.
I don't know why Coutts skip the installer way and try "to invent the wheel new" by the EnableBootDisk / DisableBootDisk in his last release?

Maybe because he doesn't want to blink the whole address range again for the canon 1000d?

Post by: Ant123 on December 10, 2016, 02:58:45 PM

The installer enables the boot flag from the bootloader context?

You also needed the address of the write and read functions.
I think 5DC installer is documented well enough.

I suspect that bootloader should be the same for different firmware versions.

But you can create your own dump using  dumpmemo() (https://bitbucket.org/coutts/1000d_dev/src/a7835d17602fe2de51fda54d372f48ede290858e/main.c?at=default&fileviewer=file-view-default#main.c-9) function

I wrote a small sequence, which will help us to find the signature.

We know that the functions are in the boot loader area, from FFFF0000 to FFFFFFFF.

The program will create a log file on the SD card with the address and content within the boot loader area.

Code: [Select]
// Function to read the content of the bootloader and write it to logfile
void booloader_mem_dump_0()
{
// Create a logfile
MyGlobalStdSet();

// We use this pointer to read the content of an address
unsigned int *p_addr = NULL;


// The address range of the boot loader is from 0xFFFF0000 to 0xFFFFFFFF
// START_ADR: 0xFFFF0000
// END_ADR: 0xFFFFFFFC (last address not relevant, therefore 0xFFFFFFFC instead of 0xFFFFFFFF)
//
// Each address holds a 32 bit value => 4 bytes, therefore we have to increment the address by 4.
// 0xFFFF0000
// 0xFFFF0004
// 0xFFFF0008
// 0xFFFF000C
// ...
//


printf("\nAddr:      Data");
printf("\n---------------");


for(unsigned int i=START_ADR; ((i <= END_ADR) && (i!=0)); i=i+4)
{
// Before assignment, "reset" the pointer to null
p_addr = NULL;

// Now point to the content of the address (in this case "i" is the address)
p_addr = *(int*)i;

// Write the data to the log file
printf("\n%x :       %x", i, p_addr);
}

printf("\n\n END \n\n");

// Set pointer to null, since we not needed anymore.
p_addr = NULL;

// Signal finish
SleepTask(5000);

LEDRED = LEDON;
LEDBLUE = LEDON;

SleepTask(5000);

LEDRED = LEDOFF;
LEDBLUE = LEDOFF;
}


// ------------------------------------------------


@shmadul and Levas

We will continue once we found the boot flag functions, therefore we have to make sure that the boot flag functions are correct.

Note: The program will not do anything to the boot flag!

Link: https://1drv.ms/f/s!AsC1K_kH7N9pbYhpDPUbSuC8Iss (https://1drv.ms/f/s!AsC1K_kH7N9pbYhpDPUbSuC8Iss)

1. Download the zip "bootloader_mem_dump.zip" and extract it
2. Build the project by "./run" in terminal (inside the folder)
3. Set the "Auto power of" to 8 or 15 minutes on your camera, we don't want to cancel the write process in between
4. Copy the .fir file on the SD card and execute it (don't touch any buttons afterwards)
5. After the sequence finish (both led, red and blue, turn on and off), copy the "address_log.txt" to your computer
6. Search now for signatures

Log file should look like this (example):

Addr:               Data
------------------------
ffff0000 : e59ff018
ffff0004 : e59ff018
....

Now, go through the file and search for the signature (see below, compare Data with the values below).

Once you found them copy the whole section (including address and data) and post it here, then we compare if we all have the same addresses.


// ---------------------------------------------
Signatures

Attention: The order is very important!

The write function should be easy to find. Compare the data values in the log file with the following values.

write_bootflag signature (order of the data):
Quote
   Data
  --------------
    E92D41F0
    E1A05001
    E3A04000
    E3500000
    13A0733E


The read function will differ from the one that is posted here.

Hint, search first all sequences that has E52DE004 and E3500000. Then search if the sequence has the rest values (3E33A013, 12833A02,  13A02040). The read functions has 2 values (unique) which differs from the sequence listed below.

Lets see if you guys can find the sequence.

read_bootflag signature (order of the data):
Quote
   Data
  --------------
   E52DE004
   E3500000
   3E33A013
   12833A02
   13A02040


PS: Can you guys provide me your log files so I can check if there is any differences between them? Just PM me with the link.

Run the program on my 1000d which has version 1.0.7 canon firmware.
Searched the log file:

read_bootflag signature:
Couldn't find something exactly similar, but I did found this

Perfect, confirmed.

I got the same result  :D .

Now we can working on the bootflag installer.

Only one thing left is, I have to find out the write_card_bootflag address for canon 1000d.

From 450D port:
https://bitbucket.org/hudson/magic-lantern/src/18ac6b0f992918c7ba6dd282c3e74ca42574561c/installer/450D.110/bootdisk.c?at=vxworks&fileviewer=file-view-default#bootdisk.c-156 (https://bitbucket.org/hudson/magic-lantern/src/18ac6b0f992918c7ba6dd282c3e74ca42574561c/installer/450D.110/bootdisk.c?at=vxworks&fileviewer=file-view-default#bootdisk.c-156)
Quote
    //~ Not sure if this is correct or not
    write_card_bootflag = (ft_write_card_bootflag)0xFFFF4140;

I have read that someone just skip it and make the SD card bootable manually.

You are strange people...

Thats because I did not have the correct setup yet. Even if have a dump I could not do anything with it.

Correct me if I'm wrong, but most people are using IDA Pro or GPL Tools/ARM console and QEMU for debugging.

I have difficulties to set it up on Mac OS, I'm considering to switch to linux and setup everything there.

Quote
On 450D write_card_bootflag() function works well.

Is it a global function that you just can call?

In the installer it is defined as typedef:

Code: [Select]
typedef void (*ft_write_card_bootflag)(int arg0);
How do you determine the address (0xFFFF4140) anyway?
Code: [Select]
write_card_bootflag = (ft_write_card_bootflag)0xFFFF4140;

step 0: setup the toolchain (you can also do it like this)
step 1: dump the firmware (see a couple posts back)
step 2: analyze/decompile the firmware dump to find function stubs
step 3: run it in QEMU
step 4: if you get this far, get in touch with a1ex to create a bootflag fir, so you can run on actual camera

Ok, I just found out how to disassemble the ROM.BIN.

As Ant123 mentioned earlier, in the "bootloader_mem_dump/main.c" just replace in "void MyTask2()"

Code: [Select]
booloader_mem_dump_0();
with

Code: [Select]
dumpmemo();
Now, compile and executed it on the camera.

After the dump finished, two files should be on the SD card.

RAMDUMP.BIN
ROMDUMP.BIN

Afterwards, follow the instruction from this link:

https://www.magiclantern.fm/forum/index.php?topic=12177.0

If you followed this thread (for Mac OS), update the "disassemble.pl" to this.

Code: [Select]
# adjust these for your needs (note final slash):
$path = "~/gcc-arm-none-eabi-4_8-2013q4/bin/";
 
# note on "strings": default is a minimum length of 4 chars.
# So if u are hunting for e.g. "FI2" add -n3
# However, it gives a lot of false positive.
$strdump = "strings -t x";
$objdump = "${path}arm-none-eabi-objdump";
$objcopy = "${path}arm-none-eabi-objcopy";

Now, looking at the main.c code, the ROM dump starts at FF800000, so modify the call like this.

Code: [Select]
perl disassemble.pl 0xFF800000 ROMDUMP.BIN
Once finished, open the "ROMDUMP.BIN.dis" in a text file.

---------------------
The write_bootflag and read_bootflag for the canon 1000d look like this in assembly.

write_bootflag:
Code: [Select]
Address reg value ASM code / instruction
--------- ----------- -------------------------

ffff5fe0: e92d41f0 push {r4, r5, r6, r7, r8, lr}
ffff5fe4: e1a05001 mov r5, r1
ffff5fe8: e3a04000 mov r4, #0
ffff5fec: e3500000 cmp r0, #0
ffff5ff0: 13a0733e movne r7, #-134217728 ; 0xf8000000

read_bootflag:
Code: [Select]
Address reg value ASM code / instruction
--------- ----------- -------------------------

ffff60d0: e52de004 push {lr} ; (str lr, [sp, #-4]!)
ffff60d4: e3500000 cmp r0, #0
ffff60d8: 13a0333e movne r3, #-134217728 ; 0xf8000000
ffff60dc: 12833a02 addne r3, r3, #8192 ; 0x2000
ffff60e0: 13a020aa movne r2, #170 ; 0xaa


Next step would be to find the addresses of the functions for the 1000D and add them to the stubs.S.
This will take time ...

Not really, I was too busy photographing, I hope my Canon 1000D does not brake anytime soon (over 53000 shutter counts), to much time-lapse  :D

I can't tell about any progress soon, because I want to use the summer and the good weather as much as possible.

Anyway, I started with the stubs.S and found so far a few function entry points (see below).

Note: Keep in mind the entry points (function addresses) are not verified yet nor tested.

Lines with "//SC" are the ones modified or updated with the addresses for the 1000D, again no guarantee that they are correct!

The 1000D GUI can now be emulated in QEMU (http://www.magiclantern.fm/forum/index.php?topic=2864.msg190254#msg190254) (same for the 450D ML (https://www.magiclantern.fm/forum/index.php?topic=8119.msg190270#msg190270)):

(https://builds.magiclantern.fm/jenkins/job/QEMU-tests/183/artifact/qemu/tests/1000D-menu.png)

What does this mean?

Porting ML on these VxWorks models just got easier by one (or maybe two) order(s) of magnitude - I hope it will be as easy as following the tutorial (https://www.magiclantern.fm/forum/index.php?topic=19417.0) and/or the walkthrough (http://www.magiclantern.fm/forum/index.php?topic=15895.msg185103#msg185103). The development tools run on all major operating systems (including Windows (http://www.magiclantern.fm/forum/index.php?topic=20214.0) and Mac (http://www.magiclantern.fm/forum/index.php?topic=2864.msg190015#msg190015)).

Good luck!

I have the Canon EOS Rebel XS DSLR. (also called the 1000d)
The Magic Lantern 1080p video recording program isn't listed on your site for my camera.

Could someone please upload the program for that specific camera?

I see a lot of people talked about making the file for this camera on this thread.
Did anyone ever do it?? I don't see a link anywhere on here to download the file for that camera.

If any of you have the download, can you please email me at mushhawk@yahoo.com?
Thanks!

PS: Would one of the mods mind sticking this thread to the "sticky posts" so that it is at the top of the message boards?
Thanks!

Unmaintained cams will not get a sticky thread. This is reserved for cams supported with nightly builds or (at least) labeled "Port in Progress". There is no ML for 1000D.
Title: Re: Canon 1000d / Rebel XS
Post by: Levas on November 30, 2017, 07:13:18 PM
There is little to none for the 1000d.
Syscal did some important first steps, but nothing near a working port.
There is nothing yet, no Magic Lantern menu not a single Magic Lantern function etc.

Best way to make use of Magic Lantern is to buy another Canon DSLR which is compatible with Magic Lantern.
Click the 'Downloads' button at the top of this page and go to the 'Nightly builds' here you can see which camera's are supported.
Many of them are released many years ago, second hand they're really affordable.
Some are better supported then others (depending on the user base and if active developers support them) I believe the Classic Canon EOS-M is one of the better supported cheap cams.

1000D is such a great backup camera. It's sad to see the development was discontinued halfway..
Sad to see such a nice cam go down in history without anything to it's name. :(

It's 2018, but ML on this camera would still be awesome.
@Syscal Any updates on development?

http://wiki.magiclantern.fm/faq#any_progress_on_xyz

Development has not been discontinued - everything from the QEMU branch (https://bitbucket.org/hudson/magic-lantern/branch/qemu) is tested (https://builds.magiclantern.fm/jenkins/view/QEMU/job/QEMU-tests/) on the 1000D firmware, too! (along with ~20 other models (https://builds.magiclantern.fm/jenkins/view/QEMU/job/QEMU-tests/lastSuccessfulBuild/artifact/qemu-eos/tests/menu.png) able to run the GUI, and ~10 models (https://builds.magiclantern.fm/jenkins/view/QEMU/job/QEMU-tests/lastBuild/console) not there yet)

I'm simply unable to take care of all these cameras alone (at least not in a timely fashion). It's now up to the community to follow (https://bitbucket.org/hudson/magic-lantern/src/qemu/contrib/qemu/README.rst) our (https://bitbucket.org/hudson/magic-lantern/src/qemu/contrib/qemu/HACKING.rst) porting (http://www.magiclantern.fm/forum/index.php?topic=19417.0) guides (https://www.magiclantern.fm/forum/index.php?topic=15895.msg185084#msg185084) and do something about it ;)

It looks like nobody is working on it at the moment. I did in the past but took a break.

a1ex still looking on the emulations side I guess.

I'm starting to looking into it again, from time to time.

Don't expect anything in the near future, but you can always join and help changing that :)
Title: Re: Canon 1000d / Rebel XS
Post by: aprofiti on March 21, 2018, 04:43:41 PM
I had a look into this a couple of weeks ago, because I could have possibility to get a 1000D at a nearly bargain price which would be fun to play with it and learn how to reverse code.
So I found a dump of 1.0.5 to run into Qemu and started to analyze it.

However, while trying to find some stubs, I have noticed different patterns into disassembled code of 1000D compared to more recent cameras (50D)
Even simple stubs which can be found searchng for strings and then go up a couples of lines, they get hard to track for the function’s entry point.

Having a dump of a 40D or 450D syde by side to 1000D could help understanding what to look for stubs and get development at the same point of the other two.
Title: Re: Canon 1000d / Rebel XS
Post by: aprofiti on March 22, 2018, 12:18:16 PM
Had some fun yesterday hunting for stubs and I noticed that I can find the same code at different address which differ by an offset...

This is using disassembply.pl with argument "0xFF000000":
Code: [Select]
NSTUB(0xFF4D6F1C, _FIO_GetFileSize)
NSTUB(0xFF4D5D1C, _FIO_OpenFile)
NSTUB(0xFF4D6C40, FIO_ReadFile)
NSTUB(0xFF4D6B7C, _FIO_RemoveFile)
NSTUB(0xFF4D6DB0, FIO_WriteFile) //CF_Test.bin

This is what I get if I use "0xFF800000" as argument to disassemble.pl. To a quick look it sems to match IDA Disassembly when hunting for loc_xxxxx (the are named sub_xxxx instead).
Code: [Select]
NSTUB(0xFF960420, CreateDialogBox)
NSTUB(0xFFD0D5F4, DryosDebugMsg)
NSTUB(0xFFCD6E68, FIO_FindClose)
NSTUB(0xFFCD6E68, FIO_CloseFile)
NSTUB(0xFFCD7090, _FIO_CreateDirectory)
NSTUB(0xFFCD6AB8, _FIO_CreateFile)
NSTUB(0xFFCD67E8, FIO_FindNextEx)
NSTUB(0xFFCD6F1C, _FIO_GetFileSize
NSTUB(0xFFCD5D1C, _FIO_OpenFile)
NSTUB(0xFFCD6C40, FIO_ReadFile)
NSTUB(0xFFCD6B7C, _FIO_RemoveFile)
NSTUB(0xFFCD6DB0, FIO_WriteFile) //tracing "CF_Test.bin"
NSTUB(0xFF865060, GUI_Control)
NSTUB(0xFF896184, GUI_GetFirmVersion)
NSTUB(0xFF8DD5DC, GuiEdLedBlink)
NSTUB(0xFF8DD5AC, GuiEdLedOff)
NSTUB(0xFF8DD57C, GuiEdLedOn)
NSTUB(0xFFD05708, msleep)
NSTUB(0xFFD05A54, task_create)
NSTUB(0xFF887050, SetGUIRequestMode) //not sure - take more argument but has same code pattern
Is code in ROM duplicated also into other smaller range instead of 0xF8000000? Do I need to prefer the second range?

What I do is using 40D's dump and stubs address to find what appears to be the same address into 1000D's disassembly, hunting for function starting with same arguments number and similar refs number, near strings or particular instructions.

Is this method of code pattern matching valid? How can I use qemu to help me in this stage?

Title: Re: Canon 1000d / Rebel XS
Post by: a1ex on March 22, 2018, 02:29:22 PM
Yes, there are multiple copies of the same ROM; g3gg0 explains how it works here (https://www.magiclantern.fm/forum/index.php?topic=6785.msg58899#msg58899). QEMU also prints the memory map, so you can see where these copies are. See the Initial firmware analysis (https://bitbucket.org/hudson/magic-lantern/src/qemu/contrib/qemu/HACKING.rst?fileviewer=file-view-default#rst-header-initial-firmware-analysis) section in the RE guide.

You need to pick the address used by Canon code. Example for msleep:
Code: [Select]
./run_canon_fw.sh 1000D,firmware="boot=0" -d calls |& grep 05708

 call 0xFFD05708(64, 0, 1, c022011c)                                             at [tHotPlug:ff813224:ffd2f5d8]
...

How to read this:
- Canon code called the function 0xFFD05708 (so that's the one you should pick for stubs) from their HotPlug task, at PC=ff813224 and LR=ffd2f5d8 (go to these addresses in the disassembly to find out the caller code)
- first argument is 0x64 = 100 ms
- the call trace prints the first 4 arguments (R0-R3), but doesn't attempt to find out how many are actually used
- we already know the signature of msleep (from dryos.h: it takes only one argument, so the others should be ignored)

There are many QEMU examples in the EOS M2 thread (https://www.magiclantern.fm/forum/index.php?topic=15895.msg185084#msg185084); however, call trace support for VxWorks is not the best (it crashes quicky because it doesn't know how VxWorks performs task switching). I have a draft patch to get the current task ID, but for some reason, that doesn't seem to fix the warnings (maybe task IDs are reused? didn't look too much into it).

I noticed that some stubs jump in the middle of a procedure and starts with a push to the stack. Is this correct?
Also some stubs form 40d like "malloc" and "free" have a comment stating "not good, points to FreeMemory/AllocateMemory" What need to be done?

Adding those stubs and this is what I currently get if I try to compile:

How can I find those RAM address?

Looking 40D "cstart" and "bzero32" are not used in stubs.s nor is warning during 1000D compilation. Does it need to be found at this stage or can get a working build to be run into qemu?
I need some time to read again M2 thread and look for something to try into emulation.

LoadCalendarFromRTC: try FFCFDA6C

cstart/bzero32 probably not needed (VxWorks model use a different method).

Need to do some digging to find the others.

I did split the ROM.BIN dump in two equals ROM0.BIN and ROM1.BIN as mentioned in the EOS M2 thread.

8388608 ROMDUMP.BIN
4194304 ROM0.BIN
4194304 ROM1.BIN

Does anyone knows how to fix this?

Try loading it as ROM1, without splitting.

When following instructions from elsewhere, consider the context. The dumper that saves a file named (NULL) includes both ROMs in the same file (so it has to be split). The 1000D dumper runs:
Code: [Select]
  int handle = FIO_CreateFile("B:/ROMDUMP.BIN");
  FIO_WriteFile(handle, (void*)0xFF800000, 8*1024*1024);
  FIO_CloseFile(handle); 

Compare the above with the memory map (from QEMU log) and expected size.

Thanks a lot.

This does the trick:

Btw, if anyone found an old ROM dump of the 1000D Firmware 1.0.5 on the internet and want to test in QEMU, renamed it to ROM1.BIN as mentioned above.

It was created the same way a1ex explained.

Both firmwares 1.0.5 and 1.0.7 are running in QEMU.

Code: [Select]
PB_Palette - the one maybe I need?
bmp_vram_real() - in bmp.c same as above
bmp_vram_info - should not be necessary as isn't asked during compilation if I remember correctly
sd_device - probably minor priority

How to find ram address for those?

I made a quick test defining CONFIG_40D (to solve some minor problems following difference in code for the others cameras running vxworks) and got a compilation without errors but no signs of ML getting loaded in qemu as it doesn't replace firmware version number and it doesn't draw ML Menu.

So I expect to find those pieces to be able to print text and draw ML menu.

Also tried to match gui_task_list from 40D using
Code: [Select]
./run_canon_fw.sh 40D,firmware="boot=0" -d ram and managed to found which subroutine return the value found into stubs.S, done the same with 1000D and also found what to appears the same code in rom's dump but as the function's address is called more than one times and return different values each time, i checked for the same value for 1000D and it shows up in console but not use if is correct to use it...
