All of a sudden, I cannot connect to this board via stlink usb cable. I tried pressing reset button, updated firmware, connect in every possible mode (hardware reset, core reset). Is there a combination/sequence of pressing buttons? In other stm32 mcu I saw a way to erase memory by connecting a resistor to reset pin and ground momentarily. Can this be done on this board and how? Anything else i can try before I trash it? Thank you for your help!
