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?

Try cycling the power.

Have your code output signs of life early in the Reset_Handler so you can see what is happening.​

Thanks Clive, this turned out to be it. The board needs an actual power cycle, not just a return to POR via hardware reset assertion.
