MSPM0C1104: MSPM0C1104 : DAP Connection Error and could not perform factory reset

Part Number: MSPM0C1104
Other Parts Discussed in Thread: UNIFLASH,

Hi,

I am trying to implement some functions that include the flash-based bootloader on the LP-MSPM0C1104 EVK. In the past, I have encountered programming failures that required performing a factory reset. However, this time I encountered the "DAP Connection Error" shown below and was unable to execute the factory reset in both CCS and Uniflash.

Do you have any suggestions on how to resolve this issue or further diagnose the root cause? Thanks.

    DAP connection error means lost connection between XDS110 (debugger) and MSPM0 DAP port.

    Double check the SWD connection / Reset / Power pin between debugger and mspm0.

    Easiest way to resolve this is to replace one MSPM0 on you hardware board.
