Module, information processing device equipped with same, and method for updating program data to update program data in module

A method for updating program data to update control programs of a microprocessor that controls an operation of an electronic component and the electronic component in a module that functions by causing the electronic component to operate, the method for updating program data comprising

• executing by the microprocessor:
• obtaining update information including blocks in each of which a header record that indicates a start of a record and includes identification information that identifies an update target, program data for updating the control program of the update target corresponding to the identification information written in the header record, and an end record that indicates a terminating end of the record are written in a sequence, and recovering the program data included in the update information by each block on a memory;
• determining whether the update target is the microprocessor or the electronic component using the identification information written in the header record;
• and
• updating the control program of the update target using the program data recovered on the memory corresponding to the update target.
