Hello, stm32n657 how to unlock the protection program? When using stm32cubeprogrammer to burn the program for nucleo-N657X0, the external flash kernel is locked. The inside of the external flash I read is all ffffff. When I erase the code of the external flash, it will report an error that it cannot be erased.
