How to debug a RP2040 CAN?

Post by scaslin »

Can I connect a Raspberry PI Debug Probe to a Feather RP2040 CAN? If so how?
Thanks

The Feather RP2040 CAN is different than the Feather RP2040 in that it does not have SWD pin head on the top side or the SWDIO / SWCLK pins broken out on the bottom.

The only way to access the pins on this particular board would be directly off the RP2040 chip. While this is possible with quality SMT gear it is less than ideal.

If you could do your development with a Feather RP2040 (not CAN model) you can have full HW debug with the Pi Probes. You could also consider using a FeatherWing CAN with a normal Feather RP2040 to have a debug unit to work with.
