MSPM0G3507: MSPM0G3507 - startup without XDS110 connected

Part Number: MSPM0G3507


Tool/software:

Dear,

My PCB is working well with CCS - XDS110.

However when I remove debugger, the processor seems not to start up.

I already disabled the BSL enable flag, so I expect the processor is not entering boot mode.

What could be the reason why the processor is not starting up?

Thank you!

    Hi John,

    Can you scope the VCORE pin while not connected to the XDS110?

    The VCORE should have a 0.47uF capacitor on it and this helps stabilize the internal connections of the device, so if the VCORE is not at the correct voltage level then there can be something with your power.

    Regards,
    Luke
