When I try to debug STOP0 feature and waking up, MCU can't be programmed by STM32 Cube Programmer. It seems that it is locked. Anybody know how to unlock it?

Did you set connect under reset?

Sorry! I need update the information. the possible reason is that the .hex file is not OK. Current I already saved one electronic board by recovering option byte. But another board can't be connected to STM32 Cube Programmer.��

How to connect under reset? set reset to low level and then try to connect?
