Hi,

I am Working on SBSFU. I have Flashed the STM32H753zi example code after flashing i am not able to flash from programmer. even after changing the option bytes RDP level 0 is set.

I have Connect another working board of stm32h753zi board i compared the parameter with flash able baord and non-flash able board.

only one thing is observed

1.not flash able board PCROP is set to :(prot_area_start1 0x00)

2.flash able baord PCROP is set to :(prot_area_start1  0xFF) 

I have tried using STMCubeProgarmmer not able modify prot_area_start1 0x00 to prot_area_start1 0xff Facing error i have attached the Screenshot below GUI and CLI both
