Part Number: LP-MSPM0G3507
Other Parts Discussed in Thread: MSPM0G3507

Tool/software:

Hi,

I'm using LP MSPM0G3507 for our project.

I use Jlink external debugger connected from J103 connector usign Arm Cortex adapter.

But I get this error while flashing using this:

Error: Failed to initialized DAP.
- No PWR-AP detected.
- InitTarget() end - Took 102ms
- RESET (pin 15) high, but should be low. Please check target hardware.
- Failed to attach to CPU. Trying connect under reset.

    Hi, Ddnr

    Please try to confirm the connection between debugger and MSPM0 Pin.

    It is very common that ARM 10-Pin debug header has soldered in wrong direction.

    You can connect these wires and test the continuity between debugger pins and MSPM0 pins

    Especially SWDIO, SWCLK and RESET. GND pins.

    Regards,
