Troubleshooting • Re: Pi4 not booting with RP2040 board plugged in

Something else I forgot to add which is relevant.

Previously I had tried using a totally different board with an RP2040. This was an accelerometer board (ADXL345) and had no additional power. Was a Pi Pico with the ADXL345 module connected.
That also exhibited the same issues (but wasn't a big deal at the time as I only needed to use it once)

The additional board with the nitehawk supplies 24V to the board with the RP2040 and the board itself has a 5V regulator on it to supply the RP2040 (and any supporting electronics).

I've run similar toolboard before but those used CANBUS rather than straight USB.

I might try a Pi5 to see if that behaves any better, but it's not a permanent solution for me sadly
