STM32F0x mit OpenOCD entsperren

English Deutsch
unlock_stm32f0_openocd.sh
openocd -f interface/stlink-v2.cfg -f target/stm32f0x.cfg -c "init" -c "halt" -c "stm32f1x unlock 0" -c "reset halt" -c "exit"

Danach musst du die Stromversorgung des Geräts physisch trennen, damit der Reset wirksam wird.

Beachte, dass stm32f1x kein Tippfehler ist. OpenOCD verwendet denselben Backend für STM32F1x und STM32F0x.
