Unsure where this should be reported, but about once every 5 minutes I have to pull the power on the picoprobe and DUT and plug them both in again to reset them. During this time, Serial/UART bridge is broken and doesn't work too. I'm not sure what triggers this, as it usually spontaneously happens when I'm not doing anything in particular beyond UART reading. Sometimes I'm connected via GDB, sometimes I'm not. If I only reset power for the picoprobe, the led stays off until I reset power to the DUT too.
Symptoms via OpenOCD:
