Hi,

Can you verify the address you are writing to? 0x00100000 is not a valid address for this device. Flash memory ends at 0x0001FFF8.

Assuming you mean 0x00010000, ensure you are unprotecting the sector before performing the erase operation again (there should be a call to DL_FlashCTL_unprotectSector).

Best Regards,
Brandon Fisher
