I leave this message on DashCamTalk but maybe here is better.

I'm the creator of the hackish firmware for the Yi4k which main goal was to debug the firmware and enable some features, thist more in the Linux part.
I'd like to hack the RTOS part.
This cam is based on A9.
I'm not familiar with C but I can do some little things.
What do you need to begin ?
Also, if you have a chan (Matrix or Discord), I can join.

Screen glitches when writing to screen buffer:
https://diode.zone/videos/watch/e29e2ce1-5b33-4e7f-be2e-ce6fa8adf5fe

Possible causes:
autoexec.ash priority?
buffer refresh rate?

Maybe figure out layer system and allocate new buffer?
Maybe use a temporary buffer?

I've been taking a break from AHDK.

One of the things I've wanted to devise is some kind of
module system. I've already gotten a lot figured out already, such as stable platform independent
code, and jumping to allocated code. Now, I just have to figure out how to read an ELF file...

TODO:

• Implement module system
• Revert build system
• Finish ashp cli

If you would like help porting your camera to AHDK, getting this would be a good head start.
If you send it to me ([email protected], Petabyte#2948), then I can help you find the addresses and stuff.

t disp info >> log
t disp csc_info >> log
dmesg dsp_debug -100 >> log
dmesg dsp -100 >> log
dmesg rtos -100 >> log 

(save this as an autoexec.ash file at the top directory of your sd card)

Build system diagram for AHDK. I decided try and do it in a unique way, by writing the build system in C rather than adding Python scripts to the makefile like Magic Lantern.
From https://github.com/petabyt/liemoth/discussions/11, but I improved it a little bit.
