Hi @happymili , pyocd is not able to find your debug probe. You probably need to configure a udev rule. If that doesn't work, please check that you have the correct firmware programmed on the OpenSDA MCU. See here for more details.

@happymili, can you provide feedback on @MaureenHelm suggested actions?
