Resolved! OH boy... I bricked my nucleo Error: Expected value for Option Byte "RDP": 0xAA, found: 0xFF
I was happily debugging some code in my NUCLEO-F207ZG, the whole morning the debug sessions (stm32cubeIDE) have been quite glitchy.Until the mcu somehow got briked and i cannot revive it.I suspect noise in the SW lines comming from some external LEDs...
