DIGIC 7 development (200D/SL2, 800D/T7i, 77D, 6D2)

[SebastianC]

6D2 1.1.1 now has limited support.  Our one dev / tester (unsure if they have an account here, CrypticKlippo on Discord), suggests it's stable.  It's the standard "has ML GUI, has no features" early build.  A good place to work from to add things.

Hi Names:

I would like ask how to do this, I am only know how to setting other ML file in SD card.Is it load in SD&CF card or other way? Thank you!

Do you mean add features to the build?  You'll need to know C, and have time to learn the code, and Ghidra, to understand the rom.  What do you know so far?

The 6D2 does not have a CF slot.

You are right. I thought I can not do any coding:)

Sorry, it's not that easy

Found a quite interesting shell command, EngMirrorDump.  This takes an integer, and returns info on a shamem region.  This includes the name of the subsystem (engine), and address offset in shamem.  It also dumps content to card.  Results from 200D.  The full list is long, but these at least are interesting and show it's useful to us:

If you know the name of an Engine, and want to monitor MMIO usage, this lets you find where it occurs.
