Hi Pritam,

The 0x00000036 diagnostic code shows MSPM0 NONMAIN is completely erased and could not be recovery by factory reset in this case. It could be caused by that NONMAIN is erased without programming, or their is connection shutdown during programming the firmware with NONMAIN.

To avoid NONMAIN to be empty during programming process, please follow the guidance in MSPM0 NONMAIN FLASH Operation Guide for NONMAIN operation. The purpose is to make sure the time window for NONMAIN empty to be as short as possible.
