OK, that’s weird, thanks for the detailled write-up. There’s a few things we can do:
- We can send you a charger board v2, perhaps your charger board v1 is developing issues.
- If it’s just a firmware issue, we should be able to see more if you could monitor the output of
tio /dev/ttyACM0for a while, especially when you plug in the charger and it doesn’t want to charge. You can just paste/attach the logs here. This is the virtual serial port of the RP2040 System Controller, and it’s quite chatty about charging/discharging/charger PD communication. CCing @zeha here who should be able to interpret the logs best.
