Hiya folks. I’m using the board with a RPi Zero W, running the latest stable Raspian 32-bit (bullseye based). I followed your guide and have had everything working, but the cmux/serial connection seems super hit and miss. Most of the time I will get cmux bomb out with ‘Cannot read /dev/serial0: Resource temporarily unavailable’. A hard (read: pull out the power and plug it back in) power cycle sometimes fixes it, reboots dont seem to do the trick. Any ideas?
Cheers,
Gricey
