I assume that you are not using mbed target hardware but some other F401 platform and a separate STLINK debugger (nucleo or what?). Can you read back the flashed code and verify it is correct. Is the code executing with a connected STLINK Are you sure the target is powered and the clock is running? Is the reset held low somehow preventing the target from starting. Did you compile for the correct target platform.
