PCROP memory protection configuration is not clearing on NUCLEO-H753ZI evaluation board.

[SPati.7]

As per information, PCROP configuration has to be cleared on regression of RDP Level from 1 to 0. But on NUCLE-H753ZI evaluation board, PCROP configuration is not clearing on regression.

But it is showing as OPTION BYTES Programming successful.

Can you please help with this, as we locked on this and not able to program application on to this FLASH protected AREA.

Hello @SPati.7​ ,

please avoid answering to yourself, as your post will be viewed as already answered.

On STM32H7, you need to change the PCROP range, giving a start address higher than the end address at the same time of the regression from RDP Level 1 to RDP Level 0

Thank You very much @Jocelyn RICARD​, it's working for me now.

Earlier i tried by PCORP config separately and RDP protection level regression separately.
