Abstract

There is provided a high-speed firmware update method which reduces the burden on a firmware developer. A server is installed which is provided with a function of receiving an image of new-version firmware (a new firmware image), comparing it with an image of old-version firmware (an old firmware image), taking out only updated files, and creating a procedure for updating the old firmware image to the new firmware image and an update image configured by update data.

Description

technical field [0001] The present invention relates to a firmware update system and an update image generation / distribution server device. Background technique [0002] When it is found that there is a defect in the software after disabling the internal device, it is generally adopted to rewrite the existing firmware to the firmware that solves the defect to solve the problem. As documents related to such a firmware update, there are, for example, Patent Document 1 and Patent Document 2 below. In addition, here, the firmware refers to all data stored in advance in the non-volatile storage area of ​​the internal device. [0003] Patent Document 1 describes a firmware update system that replaces all firmware. Also, Non-Patent Document 1 discloses a software update program frequently used in Linux, which manages software in units of packages and distributes updated software packages. [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 11-110218 [0005] N...
