Update:

I've got it compiling and linking, although there's some serious hackery involved, as well as a bunch of functions which have been dummied up, since I'm not sure where they map on the 40D's OS.

For a quick update:

I've got everything compiling, but I'm pretty sure some of my functions aren't defined in the right places, etc, so it's failing to link properly -- but otherwise it looks as though it's doable to get this working with the modern ML codebase, assuming that I (or someone else a bit better at this) untangle a few of the bad references and definitions in there.

That's as of this commit:

I've been plugging away at trying to replicate vnd's success with a modern version of ML -- which has been complicated by most of the VxWorks code being relatively unmaintained (from what I can see).

I'm most of the way through getting it to compile, although there are some deficiencies I've been trying to hack around. If anyone's interested in jumping in:

(I'd be more than happy to either accept pull requests or grant full access to the repository, if anyone else wants to work on it.)

It looks like the nasty language is still present in the "Grant of License" section of the license for downloading the v1.2.3 firmware ( "You shall not alter, modify, disassemble, decompile or otherwise reverse engineer the Software and you also shall not have any third party to do so.

rufustfirefly can you please add a little tutorial as how can I added it to 40d and CF card. sorry but I am totally new to these firmwares stuff.

The trick is to dump the .FIR file onto your CF card (presumably using a CF card reader), then use the "Update Firmware" menu option to attempt to sideload the dumper code. It won't actually upgrade your firmware, but rather attempt to run the custom code which should, in theory, spin the CF card for a bit and dump out a file containing the loaded firmware.

It could also do bad things, which it shouldn't do. If, for some reason, it locks up completely and hasn't done anything within 30 seconds or so, you might want to pull the battery.

Any idea when ML might become a stable release on 5DIII?
I am reallly interested in all of this great work, but I can't afford to risk my camera.

I've been using the nightly builds for quite some time, and it has been pretty stable for me. If you're not quite adventuresome enough to use the nightlies, just throw Alpha 3 on your camera -- it works very well. (I went with the nightly builds for RAW video support and the neat dual_iso module) I've been using it for both cinematography *and* photography, with much success.

I have built a set of dumpers, which should dump out the active firmware. If someone wants to try to load one or the other up on their 40D running v1.1.1, we should be able to get an unencrypted dump of the firmware.

It's all based off of the previous 1.0.5 and 1.0.8 work, so mileage may vary.

https://bitbucket.org/rufustfirefly/magic-lantern/downloads/108D1.fir
https://bitbucket.org/rufustfirefly/magic-lantern/downloads/108D2.fir

There's a disclaimer that this could do something awful -- but one of them should just dump a file to your card (after a flurry of activity).

If anyone wants to check my work, it's all on bitbucket:

doesnt work, only the upper display is on, battery has to be taken out...
how shall it work?

I'm having some issues getting development rolling on the 40D, primarily because I've been unable to extract an unencrypted version of the 1.1.1 firmware (as I had mentioned earlier in the thread). This has left me unable to find the rest of the function locations, so getting this port working, at least at the 1.1.1 firmware revision, isn't going to happen -- pending being able to get an unencrypted copy of the firmware to work with.

Alternately, I can try to move to using 1.0.5 or 1.0.8, which have both had their encryption keys reverse engineered. I hate backing out versions of firmware, but if it's the only way I can proceed, I may go that way.

General Development / Re: 40D Firmware assembly

« on: September 12, 2013, 08:00:31 PM »

assemble_fw essentially replaces the flasher file with the user file, with some necessary adjustment, to get the output file. The one I know about requires "injecting" your code into the right place into Canon's flasher code (40D_1_flasher.bin) to produces the user file. Please note that the flasher file as one of inputs to assemble_fw is the original unmodified Canon flasher code. In this case autoexec.bin is your code and I doubt it can be run without this step first in Canon's firmware update environment. However I don't know much about the file autoexec.bin from ML that I could be wrong.

I was following http://magiclantern.wikia.com/wiki/Packing_FIR_Files to attempt to get the autoexec.bin file generated by the ML build process to run.

I've got a 40D body laying around -- I'd be perfectly willing to dump the firmware, search for function calls, etc; I just have little to no expertise in doing any of that, and the Magic Lantern wiki seems perilously out of date. Could anyone point me to a somewhat more up to date walkthrough of either a) using the extracted firmware components to analyse or b) dumping active ROM to do the same -- and any postings, articles, or pages about digging for the locations of specific calls?

I know it seems like a tall order, but I'd love to help if anyone can point me in the right direction. I'm using a Linux machine, but I have a Windows VM handy (as well as a copy of WINE) if it's needed.

FIO_SeekFile is not really essential, especially for a very early port, so you can just ifdef it out for now.

I'll try to help out as much as I can with the 40D body that I have now. My primary interest with that body is being able to use focus peaking in LV mode (since it allows me to use my collection of manual focus lenses with more ease), but the additional features would be great, as well.

Also, somehow in the last day, 40D builds broke.

collect2: error: ld returned 1 exit status
make[1]: *** [magiclantern] Error 1

The odd part is that FIO_SeekFile should have been declared in dryos.h, which is theoretically included by stdio.c on line 11 unconditionally ; so I'm not sure why that would cause the build to break, since it worked yesterday. (It's an external function definition, so it probably references an issue somewhere else in the codebase, but I'm not horribly familiar with where to look.)

General Development / 40D Firmware assembly

« on: August 29, 2013, 12:45:13 AM »

I've been trying to build the .FIR file loader for a 40D running v1.1.1 (in-line with the version required in the Mercurial repository). I had followed the instructions on http://magiclantern.wikia.com/wiki/Packing_FIR_Files and had done the following to build a firmware loader:

• Compile an autoexec.bin file for the 40D.
  make 40D
  • Download a copy of the firmware for the 40D (v1.1.1) from Canon's website, and extract the original .FIR file from the archive
  • Compiled and run dissect_fw3 to extract the pieces of the loader.
    ./dissect_fw3 40d00111.fir 40D 40D
  • Attempt to assemble using assemble_fw.
    ./assemble_fw --header 40D_0_header.bin --flasher 40D_1_flasher.bin --user autoexec.bin --id 0x80000190 --output 40d00111-ML.fir
  • Copy the new firmware and ML files from the distribution to a CF card.
  
  Flashing this gives me working nav controls, but a blank LCD screen, even when pressing "play", "del", or "menu". Is this a deficit in my FIR file construction, or a ML issue?
  
  (I'd actually be perfectly fine with trying to compile a "bootflag" firmware update, so that I don't necessarily have to reassemble a FIR file every time I want to update from the Mercurial repository.)

The 40D is not currently supported but @jplxpto is working on porting ML http://www.magiclantern.fm/forum/index.php?topic=1452.msg66726#msg66726

Whether it will ever have raw video capability is another matter. If it does there will likely be limitations to frame size and write speeds because of the smaller pixel count of the sensor and slower CF card slot.

I had built some snapshot builds for the 40D, 50D, and 5D3, which I have available here:

https://bitbucket.org/rufustfirefly/magic-lantern/downloads

The only issue I still have is that I haven't figured out how to modify the stock FIR file to allow loading Magic Lantern on the 40D, and the instructions on the wiki seem to be a little out-of-date.

Is there currently a more "modern" version of the firmware extract/build instructions to create a FIR file for the 40D than the one located here : http://www.magiclantern.fm/forum/index.php?topic=1452.msg3856#msg3856 ?

Some of the tools listed in that don't exist in the repository anymore, so I'm getting the distinct impression that the build process has changed slightly.

Thanks!
