Some sort of v4l failure? No /dev/video* on y291ga. #949

I'm seeing rmm crash on my y291ga with 0.3.2 as soon as it's started, seemingly due to no /dev/video* devices being present. I think it's different from #892 and #909, since rmm at least seems to be working in those cases. I actually end up in a bootloop unless I comment out the call to $START_STOP_SCRIPT rtsp start in system.sh, since wd_rtsp.sh will reboot the camera when rmm dies. As such, I've got a hunch it's not the hack's fault. Any idea where to start for debugging this?

I never seen this behavior.
Which fw version do you have? I mean Yi firmware.

Yeah, it's a weird one. cat /home/homever is 9.0.35.00_202111291330.

Is there a way to turn on kernel (or other system-level) logs? It'd be nice to poke around in v4l to see what's going wrong.

I think it's not possible.

If you want to try a restore from a backup, I can send you the files.

I will happily accept your backup files. I have some of my own, but I have a hunch there's something wrong with them.

Would there be anything useful on the UART console?

Would there be anything useful on the UART console?

The log, but probably nothing more detailed than the output of rmm process.
Here the files:
