I am using STM32F767zi. I modified this board by removal of the 0 ohm resistor required to test MCU power. I connected this stlinkv3set SWD pin to this board SWD, but while debugging a programme, it displays the error "Error in MI command final launch failed." Can somebody assist me in resolving this problem?

Check with STM32 Cube Programmer. Confirm connectivity.

An unpowered MCU will not be responsive to connection attempts.

If it's connected on the cube programmer, does it mean it's not burned? But it is not displaying the value on the screen. How can this be resolved?

Burned? What value(s)?

If you can connect to the STM32 and read/write memory content, then at least that portion is viable.

Now focus on settings and usage by CubeIDE and GDB which are causing problems there. See other posts on same error..
