Techniques related to updating software (e.g., firmware, code or applications) in an electronic device or system are disclosed. According to one aspect of the present invention, an updating communication program is retained a micro control unit (MCU). When needed, the updating communication program is executed by the MCU to download an updating executable program from an external device (e.g., a computer device or portable device).
