MSPM0C1106: secure programming process for mass production

Luda Zefer
Prodigy 10 points

Part Number: MSPM0C1106

would like to clarify the recommended secure programming process.

Our current programming setup is based on SEGGER J-Link

Could you please advise on the following:

  1. Is MSPM0C1106 fully supported for production programming using J-Link?
  2. What is the recommended procedure to program the application firmware and then secure the device?

    Hi Luda,

    MSPM0C1106 is fully supported by Segger for both debug probes and production programmers. To clarify, the J-Link is classified as a debug probe while the Flasher products are their programmers. The following linked MSPM0 NONMAIN Flash Memory Configuration Guide goes into details on the recommended practices for securing the device using a custom NONMAIN configuration.

    We recommend:

    1. Erase Main Flash
    2. Erase NONMAIN Flash
    3. Program NONMAIN flash
    4. Program Main Flash

    This will minimize the time where nonmain is erased. If the device undergoes a bootrst or stronger in this state or if nonmain hasn't fully been written the device will become irreversibly locked.

    Best Regards,
    Brian
