Hi,
I designed a custom RP2040 but I'm having issues getting it to connect over serial once micropython is flashed. I have verified micropython using picotool.
I can see 1.1V and 3.3V on the pico; sadly, I don't have any way of verifying the crystal is oscillating but, I have used the recommended crystal and caps. I have also tried removing the caps to see if it made any difference.
One error I noticed with my design is I'm using a 3.3V pore to connect all the 3.3V pins rather than running individual traces. I'm not sure if this would cause any issues.
Any advice would be much appreciated!
