METHOD AND APPARATUS FOR GENERATING FIRMWARE UPDATE FILE AND UPDATING FIRMWARE BY USING THE FIRMWARE UPDATE FILE

摘要

Provided is a method of limiting updating of firmware by distinguishing between model code that represents a group of hardware having firmware program codes are compatible with each other and model code that identifies each hardware belonging to the group. The method includes generating a data body having firmware program code that is to be updated; generating a data header having model code of hardware to which the data body is to be applied, wherein the hardware model code comprises first model code representing a group of hardware having firmware program codes are compatible with each other and second model code identifying each hardware belonging to the group; and generating a firmware update file by combining the data body and the data header.
