    Hi Zoey,

    If the SWDIO pin is re-purposed in application code, you can issue a factory reset to be able to re-program the device.

    Section 7.1 in the MSPM0 MCUs Development Guide outlines how to factory reset a device. I would recommend using the Factory Reset Manual option.

    Debugging will not be possible if the application sets the SWDIO pin to have GPIO functionality during runtime.

    Best,
