Agree RP2040 / RP2350 is great for debug and UART access! I wrote[0] about using picoprobe with this device as well.<p>[0] <a href="https://danielmangum.com/posts/risc-v-bytes-accessing-pinecil-uart-picoprobe/" rel="nofollow">https://danielmangum.com/posts/risc-v-bytes-accessing-pineci...</a>
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
Doesn’t look like openocd is getting dirtyjtag support any time soon, the PR has stalled since 2003 it seems <a href="https://review.openocd.org/c/openocd/+/7344" rel="nofollow">https://review.openocd.org/c/openocd/+/7344</a>
