MSPM0C1104: MSPM0C1104 debug

Part Number: MSPM0C1104

Hi Teams,

The customer is currently using SWDIO to reuse GPIO INPUT function. Once the program is burned in, it cannot be debugged or burned again. How can this be resolved?

Thank you!

    Hi Vayne,

    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,

    Owen
