Using "ioreg -p IODeviceTree -l", the only "system-id" in there is this: Machine #1 (MacPro): | { | "SystemSerialNumber" = | "Model" = | "DevicePathsSupported" = | "name" = |...

It seems like the HW UUID should seed from something like the machine's serial number, or base MAC address, or something like that. I don't have an explanation for why...

You can run (simpler) programs on the webcam Pi. You have to get them there, either by incorporating them into a build, or uploading them to /tmp through the USB...

I'm not actually having much trouble debugging, yet. I can do most of the work on the Pi 3B+ that's hosting the Pi 0 during development, and then just upload...

The tinyplay program, from the tinyalsa project, seems to be all that is necessary to play .wav files. (It can't convert formats, but I can do that beforehand on a...

I have been able to use buildroot to work with a modified 1.91 project, and can configure it (in showmewebcam-master/config/config) to include utilities like tinyalsa, ffmpeg, strace, etc. However, no...
