My codes are stored on bank2 and I am trying write some manufature data into BANK2 (sector 14) of internal flash.
Howerver it always fail in erase stage dut to the flag of PGSERR is raised.
If I change to write data to bank1 (sector7) this symptom not happen again.
Is there limitation that code cannot access internal flash that within same bank on STM32H7?
