MSPM0L1105: MSPM0G3507 could not connect to the jlink emulator

dear

        When debugging the NVM of MSPM0G3507, the error operation wrote 1K bytes in the address of NON MAIN 0x41C00000. After the MCU was powered up again, it could not connect to the jlink emulator. How can I restore the debugging of the JLINK SWD? The 1K bytes that the loop writes look like this: FLASH equals 1024: for (i = 0; I & LT; Flash i + +) write [ I ] = I;

any advise？thanks in advance

    HI,

    You have wrote invalid data to the NONMAIN memory, and change the BCR and BSL configuration with the wrong CRC data. I am afraid nothing can be done to save the chip. 

    Please remember DO NOT write invalid data to the NONMAIN. 

    Best regards,
