I accidentally set output port to all port pins of GPIOA,B,C,D,E,F and G. and i upload the code to STM32F767Zi and after that i can't access STLINK connection to pC. i can't program it. please help me...
Not really a Keil problem.
Use the ST-Link Utility to connect under reset.
Does the F7 still have the Boot pins to allow booting from the internal system bootloader...?
Yes, pull BOOT0 High, and erase the part
