Offtopic. You are asking for ports for new hardware. This thread is about porting an existing ML version to higher firmware version.

See https://builds.magiclantern.fm/ -> "Your camera is not listed?" and linked threads for Digic VI and VII.

Below -> ROM dumpers for 5D4 and 6D2 available: https://builds.magiclantern.fm/ -> ROM dumpers


I'll add another link:

ML on EOS-M2

Note that even a camera that should be very similar to the cameras that have already been ported to ML can present quite a few challenges. Cameras like your 5D4 and 6D2 use Digic 6, 6+ and 7 processors. So far ML is working on cameras with Digic 4 and 5 processors.

Porting ML shouldn't require any physical modifications. In fact much of it can be done via QEMU once you're got a firmware dump.

Of course invasive hardware hacking is another way to figure out what makes digital cameras tick -- or rather click?



Hello dfort,
I'm having issues porting the firmware, for the EOS 2000d, everything's fine until I try to disassemble with the script, the script returns
Offset + filesize - 1 > 0xffffffff. We can't wrap around!

And I tried to adjust the path but it didn't work, what can I do?


The 2000D has a Digic 4+ processor. Not sure what offset is needed when disassembling.
