Off and on I’ve been trying to get the Clockwork Pi uConsole with a Raspberry Pi CM4 in it to work with Nerves.
Today before packing up for Code BEAM I actually got it going!
The hacked-at system is available here.
The part that eluded me from their original code was that some of the drivers were not compatible with Linux beyond the 5.1 or whatever they made it for. Connor helped me find a good patchset someone made for Raspberry Pi’s Linux kernel. I’m not finding the link right now.
I set it up. Then I had some challenges effectively moving the .dtbo files from the build directory to the right place.
Finally wrapped that up and it works.
I’ve done a number of iterations while travelling but haven’t managed to rotate the text mode display.
I also haven’t gotten the wifi working. If I don’t mount it in config.txt and run dtoverlay devterm-wifi it will tell me error -30 and that it failed to write /config which seems very odd.
I almost got USB connection working but the USB-C ports are weird on Pi-derived devices sometimes and this seems weird. I think I might get it if I find my OTG USB-A-to-A cable.
