[amar_1]

I am currently working on the STM32H7S78-DK board & after building GPIO demo present Example code from git repository of that STM32 provided, while flashing binary from the STM32 programmer I faced issue it is mentioned below

• When code is flashed from STMcube programmer it sometimes flashed and sometimes showing error that , core is locked or core is under reset
• When code flashed successfully , I did not get expected result (Ex. LEDs not blinking)
