AI Technical Summary

Problems solved by technology

Therefore, when the firmware size increases, the transfer time increases relatively much
[0005] Second, the program code that does not need to be updated will also be transmitted to the electronic device, so it is a waste of time
This not only wastes bandwidth but also reduces update efficiency

Embodiment Construction

[0045] Please refer to FIG. 1 , which shows a schematic diagram of a firmware update system according to a preferred embodiment of the present invention. The firmware update system 100 includes a first device 110 and a second device 120 . The first device 110 and the second device 120 are, for example, an embedded device and a personal computer, respectively, or, for example, a personal computer and a remote server.

[0046] The first device 110 includes a first storage unit 111 , a transmission module 112 and a self-update module 113 . The first storage unit 111 is, for example, a read-only memory (ROM), a flash ROM (flash ROM) or an electrically erasable programmable ROM (EEPROM). The first storage unit 111 is used for storing the first image file 114 . The first image file 114 has a first header 115 , a first file system 116 and a second file system 117 . The first file system 116 and the second file system 117 are, for example, program codes and preferably program codes...

Abstract

A firmware updating method is used for updating a first mapping document of a first device. A first mapping document comprises a first docuterm, a first document system and a second document system. The firmware updating method includes the following steps: at first, transmitting the first docuterm to a second device which comprises a second docuterm and a third document system; in succession, comparing the first docuterm and the second docuterm by the second device; then combining the second docuterm with the third docuterm by the second device so as to generate a second mapping document; then, outputting the second mapping document to the first device; furthermore, updating the first document system of the first mapping document into a third document system according to the second mapping document.

Description

technical field [0001] The invention relates to a firmware update system and method, in particular to a firmware update system and method for comparing file header information and updating part of the file system accordingly. Background technique [0002] An embedded system is a computer system that integrates software and hardware and has specific functions. The software of an embedded system is also known as firmware and includes a set of instructions to perform specific functions. Many electronic devices such as personal digital assistants (personal digital assistants, PDAs), telephone systems, copiers, elevators, etc. are embedded systems. Since the embedded system is widely used and the industry is committed to expanding the functions of the embedded system, how to update the firmware is a very important issue at present. [0003] The current firmware update method connects the electronic device to a personal computer, and then downloads a complete image file (image) ...
