Stm32 options bytes get randomly reprogrammed even when flash not unlocked

2020-03-16
I have a strange issue with my Stm32F767 project. We've seen with some boards randomly RDP will be enable to level 1, and BOOT0/1 are set to 0xffff. ESD seems like a potentially likely cause, but is there really enough energy in an ESD event to cause...

Board does not boot after readout protection enabled.

I have a project based on an Stm32F767. If I load the hex file and then manually enable readout protection to level 1 with the STLinkV2 utility, the board fails to begin to execute code after reset. Why? What is the correct way to use this feature?
