I managed to blur the image of the LCD. I now have to know the coordinates valid in order to draw a rectangle.

I used this STUB, and wrote somewhere in vram0.

NSTUB(0x1E450, bmp_vram_info)

In the coming days, I'll want to have a bmp_printf(...) function to write text on the display.

Once you get it, I want to improve the boot process.

you should start porting ML to the 40d, clone the latest repo and look for CONFIG_5DC, maybe add #define CONFIG_5DC CONFIG_40D and copy the same diretory structure / entry.S of the 5dc. All of the changes for the 5dc in menu.c should be valid for the 40d too.

Thanks Coutts ... I'm working on it

Good news ...

In recent days, me and Alex, we can give a good progress in 40D port.

Finally, we have a "Hello World" working ...

soon I'll post a picture here ...

Awsome. My Camera is still broken and im trying to repair it.

Me and many others are silently waiting for Good news

With a little time and patience, one day will come true ...

The Coutts and Alex have done an excellent job with 5DC.
I think that much of this work can be useful for the 40D.

Do you have a fork with your 40D work on bitbucket? I'd like to "follow" it

Nanomad. I haven't shared my code in this repository.
I sent my initial developments to Alex's email.
After that, he then began to integrate it into the ML.
We've been working together a few hours.
I loved working with him on this project, but we had little time.

Right now, I have a problem displaying the menus on the LCD.
I suspect there is a problem of any competition in memory access, calculations wrong, wrong resolutions or access buffers that were allocated dynamically and are already invalid.

Yes, I am thinking to create a repository on bitbucket

I also hope to have their precious help

Hi guys

My 40D camera now say :

"Magic Lantern is up and running...3 tasks started."

... but has serious problems on the LCD. I still can not see the menu of ML

I can only see messages like "Hello World!" and sometimes appears at the top of the image a green rectangle,
a little blurred with pixels of other colors. I think is the menu! And sometimes the entire screen flashes.
It seems that, we switch the color palette. This is something very strange happens.

I'll have to ask someone for help ... I still can not fully understand the code of VRAM.
We should be using buffers invalid or the wrong dimensions. If I can I do some tests for next week

Guys? Someone can help me on this? ... Maybe you Alex ...

Thank you in advance!

I'll keep you updated with the latest news ...

I think that once the problem of LCD is resolved, we can say that we have the ML running on 40D

Be patience, ... we still have much work ahead!

I think that once the problem of LCD is resolved, we can say that we have the ML running on 40D

Be patience, ... we still have much work ahead!

Good job. I am waiting.

Jplxpto,

First: impressive progress for your first port!
if you could publish your code (bitbucket fork?) we can better help you...
for example see missing stubs/consts

Hi Indy

Will I have a great honor to also have your help.
You have given me a fantastic help. I am very grateful to you all.

My current code is all in hudson repository of ML.

For more details we can exchange some PM.

Sounds good.

Point the camera to something recognizable and dump roughly 1MB from the VRAM address to confirm it.

Another way to find VRAM buffers: look for EDMAC registers. In digic 4, these are c0f04008, c0f04108 ... c0f04f08, then c0f26008, c0f26108 etc. One of those registers should point to the LiveView buffer.

I found this :

MEM(0x00007648) = 0xC0F0B008

I found three 40D v 1.1.1 fonts:

I used the script find_fnt.py but I changed it a bit.

Code: [Select]

...

print 'Find bitmap fonts in Canon DSLR firmwares'
print 'Arm.Indy. based on work by Pel, Trammel Hudson and A1ex\n'

off = 0
while off < len(m) and off <> -1:
  off = m.find('FNT\0', off)
  if off <> -1:
    val = getShortLE(m, off+4)
    if val==0xffd8 or val==0xffe2               or val==0xffec:
      parseFont(m, off, base)
    off = off + 4
...

Code: [Select]

python ../../../../find_fnt.py 40d.111.ROMF1.0xFF800000.bin 0xFF800000

Sounds good.

On 5Dc, ML changes the palette, so it's probably normal. Can you post some screenshots?

You can map the button codes, and once this is done, menu should be usable.

Indy · « **Reply #120 on:** October 09, 2012, 08:23:27 PM »

At least someone else is using this script ;-) maybe I should put them on bitbucket...

@jplxpto
your files on bitbucket are one week old and comments are "not tested"
- what is working/not working ?
- what are missing / working stubs and consts values ?

Indy, you're right files have one week ... in the last days I had little time to work on it.
I was just looking for some stubs and clarify my doubts with other forum members.

Yes I used your script and it was useful to confirm the addresses of fonts.

I have enabled the bootflags and dump the ROM dump.

Last week, me and Alex located the HD & BMP VRAM, but I still do not know the address of the LV VRAM.
I already have some ML threads running but, still could not see any menu. Is there any problem in presenting the image on the LCD.
I should have solved this, but my lack of time and knowledge has not allowed me to resolve this issue.
There is also a problem in the image display on the LCD.
The can.on menus are constantly changing color. The problem must be related to the color palette.
I already found the addresses of color palettes and some stubs used by Alex in 5DC. I did not upload but did post here.

jplxpto · « **Reply #122 on:** October 10, 2012, 02:58:07 AM »

Some more stubs

40D v1.1.1

Code: [Select]

NSTUB(0xFFD4F338, TryPostEvent)
NSTUB(0xFFD4F398, TryPostEvent_end)

NSTUB(0xFFD56470, TryPostStageEvent)
NSTUB(0xFFD564FC, TryPostStageEvent_end) // PendStageEvent

NSTUB(0xFFD6A1C8, get_current_task) // 0x22E00
NSTUB(0xFFD69F8C, get_task_info)
NSTUB(0xFFD6B8B0, get_active_task_list)

jplxpto · « **Reply #123 on:** October 10, 2012, 03:45:29 AM »

I commented out the calls to the set_ml_palette and set_ml_palette_if_dirty functions and,
now the colors are presented as they were before.

I have not created my repository to share my changes with you, but I hope to do that later this week.

After upgrading my project with the latest version of ML available,
I checked that the code does not compile.
Some more stubs are needed to 40D. I however able find what was missing.

I'm now using changeset a53eef8d1c7d.

Code: [Select]

NSTUB(0xFFD6A1C8, get_current_task) // 0x22E00
NSTUB(0xFFD69F8C, get_task_info)
NSTUB(0xFFD6B8B0, get_active_task_list)

My next step is to draw a rectangle on the screen to see if I understand what is happening with the VRAM. Later, I'll validate events. The ML is already processing some events but I have to review all the constants.

a1ex · « **Reply #124 on:** October 10, 2012, 07:59:28 AM »

For drawing, use bmp_fill and bmp_draw_rect (they both have the same syntax, so rectangles drawn with those two functions should overlap).
