"I don't now how to do all the things on the EOS R without ML (f. e. Intervalometer, Motion detection, the modules). "

At least simple things like Intervalometer, would work with Canon Basic.

We have "factory" evprocs that ML calls for this reason. They work, unless they didn't and leave camera in weird state.

They have a bug in sw1/sw2 handling - callbacks are installed for that and if eg focusing fails, callback is not removed. It fires on next (even real) shot attempt, with null pointer (iirc on recursive lock) - crashing the camera.
If it even won't crash (if I reset CBRs myself after failed attempt), it leaves camera in a state where it thinks photo is developing but it is not.

If there's another possibility on EOS firmwares, I'll be happy to take it as like I mentioned on previous page I spent too much time on those functions that we used previously :)

Only boring internal stuff, but nothing usable for the end user. Research and development is still on going.

It's hard enough that it couldn't be understood in two languages, apparently.

is it possible for an early release? the shutter curtain close mod that you showed already has value for end user.

Some fun tests.

Benchmarks with the cheapest UHS-II card I was able to get (Lexar LSD64GCB1667)



In desktop UHS-II reader:




What about overexposure warning in LV?

Yes, ML has this feature on older cameras. But DIGIC registers doesn't work the same way as before.
I was able to alter threshold and highlight style by poking registers, but I'm not able to activate the function (yet?). For now it works like warning you can enable in Play mode.

Two different firmware 1.8.0.
https://gdlp01.c-wss.com/gds/8/0400006288/01/eosr-v180-win.zip
https://gdlp01.c-wss.com/gds/8/0400006288/02/eosr-v180-win.zip

Confusion confirmed. There are at least two versions of R 1.8.0 firmware ???

One that all development is based on:
Code: [Select]
K424 ICU Firmware Version 1.8.0 ( 7.3.9 )
ICU Release DateTime Jul 27 2020 18:48:59

First file has modification date of 21.10.2020. It holds the same firmware as above, as 1.8.0 was publicly released on 19.11.2020.

One that we just found about (this one matches modification date of 2nd file):
Code: [Select]
K424 ICU Firmware Version 1.8.0 ( 7.4.0 )
ICU Release DateTime Feb 4 2021 17:01:29

They differ enough (everything is slightly shifted, differently aligned) that it will not work on newer version.

You can verify which one you have with Canon Basic script, mentioned on previous pages:
Code: [Select]
private sub Initialize()
    CamInfo_Debug(1)
end sub

It contains some info, including:
Code: [Select]
<FirmwareVer>
    <Internal>0.7.3.9</Internal>
    <Major>1.8.0</Major>
</FirmwareVer>

Currently we are doing some research on PTP. There is a tool called ptpcam` in https://github.com/coon42/magiclantern_simplified/tree/ptpcam_add_more_canon_codes/contrib/ptpcam which allows reading some camera info via PTP. Every camera exposes all PTP commands it supports which can be queried via PTP. I've added alot of missing PTP command ids to ptpcam and got the following list of command IDs by executing:

Code: [Select]
./ptpcam --list-operations

RP can run Doom btw:


In this hack ML is loaded into 4K clean HDMI buffer 0 and Doom into 4k clean HDMI buffer 1, as Doom needs a plenty amount of code and work ram size. Both buffers offer 4MB of memory each. Thus one shouldn't enable 4K clean HDMI while playing Doom or Canon firmware will overwrite ML and Doom code and camera will crash horribly. I may port this into a generic ML module later, so it can be run on any camera.

Good afternoon, I have an RP camera, and I really suffer from the fact that with my favorite lens, the cropped frame is forced to turn on.
I would like to fix the firmware and make this feature not work. A very simple fix, no menus, no testing on many lenses, no syncing to the main ML code base. I think it would be on the level of the fix above, where the shutter closes when the camera is turned off, simple enough. I have decades of experience developing for microcontrollers, and some experience reverse-engineering firmware. I really want to try this, and if I succeed, I'll post the result.

However, I have a distinct lack of understanding of reverse engineering the firmware for EOS/ML.

1)How do I get the firmware from my camera? Can I take the file from the website, modify it and flash it as usual, or are there mechanisms out there that don't allow me to flash the modified file?
2)If I can't do that, do I have to download the firmware from the camera itself? I've seen it done by people in this thread, but it was sketchy and I never figured out exactly how to do it. Can it be done by downloading the code to the card or does it require access to the insides of the camera?
3)What are the risks in reading and writing firmware? Can I brick the camera in a way that requires something non-trivial steps to repair?
4)Should I fix the firmware code directly or can I write a small program which will run at startup and patch the camera's memory, to reduce the risk of the camera turning into a brick?
5)What is the best way to disassemble the firmware? Programs, tools?

Please feel free to RTFM and poke me in the documentation. I need directions, not a teacher's help at every step.

Yes, ML has this feature on older cameras. But DIGIC registers doesn't work the same way as before.
I was able to alter threshold and highlight style by poking registers, but I'm not able to activate the function (yet?). For now it works like warning you can enable in Play mode.

Not valid anymore. I spent some time and found out that now this is a set of three registers, not a single one.

And both overexposure and underexposure warning can be enabled independently at the same time with different visual settings.

And while running in Clean HDMI mode, one can configure HDMI and LCD to display different things, with independent thresholds and styles :)

Complete registers documentation is on wiki.
This should apply to all Digic 8 models (+/- clean hdmi limitations), I need to explore code on Digic 6 and 7.

[e] Digic 6 and 7 use different register addresses and a bit different values, but capabilities are generally the same. I added those in Digic 6 section of Wiki.

PoC will follow soon.

hi guys,
great to see that there's development on this build.

one question: how likely is it to have a canon R build at some point in the near future, shooting 14bit raw video in 4K, while keeping the AF methods available (eye tracking in particular).
I'm thinking whether to get a 5d mk III and enjoy ML, or wait for an R release.

Thanks.

Hi,
and what about stripped-down ML with only LUA scripting and https://www.magiclantern.fm/forum/index.php?topic=18083 ? ;)
That'd make my day/week/month/everything

well, the fact is, that i've been using ML for nothing but this script on 6D + 650D and it's a pitty, that i can't do the same on R. but i haven't contributed to ML at all, nor do i have any skills to do that, so all i can do now is just silently wait ;)

There's no such thing as "only lua scripting" anyway.
Lua can only expose what is already supported by the build. If you strip something from build, you strip the lua ability to use that.

Not to mention that Lua is probably completely broken on Digic 6+, and will be not trivial to fix.

Existing code crashes camera with seemingly random reasons. We don't release anything for your own safety. Do not request any builds as those requests will be ignored.

Not at all likely to come true this year.

I see post was deleted? (or not approved by mod). Anyway,  there will be no RAW recording support, unless announced otherwise. Hardware is different.

Hi,
looks that I missed that post - since newcomers are moderated and may show up with delay.

Easiest way to grab the firmware is via Canon Basic script - see General Development section, pinned topic.
We don't modify / flash original firmware - so I can't answer that question. Magic Lantern is altering DryOS bootloader in RAM, and then just runs as regular task(s) in DryOS.

Yes, because we do not redistribute firmware dumps. Those contain copyrighted Canon code.
You can access UART (Reverse engineering section, pinned topic) and do some things directly from bootloader, but that is not needed.

3)What are the risks in reading and writing firmware? Can I brick the camera in a way that requires something non-trivial steps to repair?
Reading - no risks. Writing - again, can't answer. Main firmware runs from 25xx flash on board so it is theoretically possible to desolder those and program externally.
If you break MPU firmware (hardware "hypervisor", controls buttons, some peripherlials comm and most important - power to main CPU (ICU)) it will get tricky, as this one stores firmware in internal flash - and @coon probably found Jtag there just last week. We don't touch MPU code though.

4)Should I fix the firmware code directly or can I write a small program which will run at startup and patch the camera's memory, to reduce the risk of the camera turning into a brick?
See 1a - we do exactly that. Patch in RAM (what we can) and just run our own tasks that alter camera state where possible.
On older models it was possible to use so called Cache hacks to patch ROM code on runtime - but this feature is missing from new generation CPUs.
In theory you can use MMU to remap whole pages of ROM with patched code - however we don't do that (yet). CHDK uses that functionality, just so far we didn't have to patch ROM directly (again - yet), thus it wasn't investigated.

5)What is the best way to disassemble the firmware? Programs, tools?
The best tool is the tool you know to use. Nowadays we mostly use Ghidra,
Too many Canon cameras.

I just got a Canon RP and I have some experience with Ghidra and reverse engineering some though nothing this complex.

I’d be interested in helping the project out if anyone on the development team could help to bring me up to speed.
