Hi,

I am trying to configure STM32F427 option byte to enable read out protection. I can configure it via ST-Link Utility; first I download my actual code that will run on microcontroller then I enable the read out protection via ST-Link Utlity. When I do this, protection is enabled but the code on microcontroller does not work anymore. Am I doing someting wrong here, what is your opinion?
