I have built my own board with STM32F7-45VGT6. I have successfully programmed it with ST-LINK v2 (not the original one though) and now I cannot even connect with MCU.
I use ST-Link Utility from ST and SWD interface. It can be the case that I use SWD pins as output and in my code I set them as GPIO output. Can it be the case?
Nevertheless, I connect my reset pin to GND and set "Connect under reset" option in ST-Link Utility but it doesn't work... What can I do?
On the Internet, I have found something about using BOOT0 Pin, but I don't know exactly...
