Picoprobe

Picoprobe allows a Pico / RP2040 to be used as USB -> SWD and UART bridge. This means it can be used as a debugger and serial console for another Pico.

Documentation

Picoprobe documentation can be found in the Pico Getting Started Guide. See “Appendix A: Using Picoprobe”.

TODO

  • TinyUSB's vendor interface is FIFO-based and not packet-based. Using raw tx/rx callbacks is preferable as this stops DAP command batches from being concatenated, which confused openOCD.
  • Instead of polling, move the DAP thread to an asynchronously started/stopped one-shot operation to reduce CPU wakeups
  • AutoBaud selection, as PIO is a capable frequency counter
  • Possibly include RTT support
