    Good to see an "organic" J-Link + RISC-V use case :)

    Jlink is closed source.

    Better use dirtyJTAG on an rp2040.

      Doesn’t look like openocd is getting dirtyjtag support any time soon, the PR has stalled since 2003 it seems https://review.openocd.org/c/openocd/+/7344

      Agree RP2040 / RP2350 is great for debug and UART access! I wrote[0] about using picoprobe with this device as well.

        I tried to use picoprobe to debug an nrf52 chip, it failed to even detect it.. All that’s officially supported is using it to debug a raspberry pi, and maybe if I added 100Ohm resistors to the lines I would have had better luck, but.. alas
