    ST have Application Notes which show how to do this - look for "In-Application Programming" (IAP)

    It has nothing to do with Keil.

    Make sure the target addresses are set correctly, check Target pane in Keil.

    Make sure the vector table is set to the correct address, check SystemInit().

    Make sure that the binary data is correctly written to the memory, and matches expectation, check the vector table and entry points.

    Make sure that the control transfer code operates correctly, use the debugger, step into the code, confirming it gets into the Reset Handler and SystemInit() functions correctly, as expected.
