I'm working on a TWR-K55F180M board playing with FreeRtos and the watchdog timer. I seem to have gotten the board into a state I cannot recover from. When I try to start debugging, I get the following message: "arm-none-eabi-gdb.exe has stopped working". If I reset the board, a previously successful piece of code that uses the watchdog runs. Since the watchdog config can only be written once, the debugger can't turn it off. How do I keep my old code from running and initializing the watchdog?
