Restart a STM32G070 MCU

[MZimm.3]

I am currently trying to start the bootloader in the system memory on the STMG070 from my application. To do this, I have changed the bits of the boot mode via software. Now it happens again and again that I can no longer access my MCU with the debugger. I think that the error is caused by incorrect FLASH settings. Is there any way to get the MCU back into debug mode to correct the settings?

Hello @MZimm.3,

Try reset using NRST pin to reset the STM32 hardware, choose connection method "Connect under reset".

I advise you this FAQ: How to make sure the STM32 starts properly in our design?
