Abstract

The invention discloses embedded equipment and an on-line updating system and a method of a firmware in embedded equipment. The embedded equipment comprises a storage module, a downloading module and a guidance loading module, wherein, the storage module comprises a current operating firmware storage area and a firmware mapping file storage area; the downloading module is used for downloading the firmware mapping file of which the downloading edition is superior to that of the current operating firmware, and storing the firmware mapping file into the firmware mapping file storage area; and the guidance loading module is used for loading and calling the firmware mapping file. The embedded equipment and the on-line updating system and the method of the firmware in the embedded equipment of the invention are characterized in that by adopting the method, the firmware mapping file is downloaded from a server via a network and stored into the corresponding storage area; and after the system is restarted, the firmware mapping file is guided to load. Compared with the prior art, the invention simplifies the firmware updating steps, improves updating speed and success rate, lowers updating cost and prolongs the service life of the embedded equipment.

Description

technical field [0001] The invention relates to the field of embedded devices, in particular to an embedded device, a system and a method for online upgrading of firmware in the embedded device. Background technique [0002] In embedded devices, to upgrade the kernel firmware or file system firmware, the target board is generally connected to the host, and the upgrade process is completed through the JTAG port, serial port or network port. The implementation of firmware upgrade in this embedded device needs to use a special tool to burn the firmware to be updated, and the operation is relatively complicated. It is a difficult job for ordinary users. Contents of the invention [0003] One of the objectives of the present invention is to provide an embedded device, a system and a method for online firmware upgrade in the embedded device, simplify the steps of firmware upgrade in the embedded device, and improve the speed and efficiency of firmware upgrade. [0004] The pre...
