Is it possible to add logging that shows the increments of source and dst address? And what is the DFU_BANK_1_REGION_START address?

You should check the return value from sd_flash_write() and the while () should either be removed or replaced as you're using the NVMC directly.

Yes, it's the sd_flash_write() leads to exception....

temp_add = 0x4b000

data_to_write_to_flash = 0x20003890

Hi Yuval,

Have you confirmed that it's the sd_flash_write() that leads to the exception? In that case, can you check what the source and destination address were at the time the exception was raised?

Also, unrelated to the issue here, but since this is based on SDK 11, please make sure to include workaround for errata #108 in bootloader and app before going to production ([108] RAM: RAM content cannot be trusted upon waking up from System ON Idle or System OFF mode).

Best regards,

Vidar
