    We have absolutely zero knowledge of what you are doing other from what you tell us. You have told us nothing that would enable us to help you.

    Try using separate batteries for the MCU and the motor and also opto-couplers between the MCU's outputs and the motor.

    share your schematic and software, maybe you are not switching the h-bridge correctly.

    Excuse me, but this thread is reserved for clairvoyants and psychics. We don't need schematics or information about the problem.
