Enabling Secure Protection with RDP0 but Option Byte Programming change failed

[HAHA6]

Hello,

 My project is based on the STM32H753 chip.

I Using the STM32CubeProgrammer and try to set the RDP level from 0 to 1, I get the error "Error: Expected value for Option Byte "RDP": 0xBB, found: 0xAA".

I only enable the Secure Protection.

How can I solve this issue?

Any assistance on these issues would be greatly appreciated.

Thanks,
