Abstract

The invention discloses a multi-firmware embedded system and a firmware update method thereof. The system comprises a processing unit, a main storage unit, and multiple kinds of system firmware which are stored in a plurality of storage blocks. The method comprises the following steps of: receiving firmware to be updated; searching addresses of the storage blocks, and identifying in-use firmware and non-use firmware in the system firmware; writing the firmware to be updated into the storage blocks corresponding to the non-use firmware to replace the non-use firmware; comparing the in-use firmware with an edition of the firmware to be updated so as to judge whether the firmware to be updated is an update edition or a backtracking edition of the in-use firmware; setting an update parameter according to a comparison result so as to indicate the update edition or the backtracking edition; and restarting the embedded system, and selecting the system firmware of which edition data corresponds to an update parameter from the storage blocks. Due to the adoption of an electronic product, updated firmware can be used for providing service, and the electronic product can still be kept operated without obstruction even after update failure.

Description

Technical field [0001] The present invention relates to an embedded system and a method for updating its firmware, in particular to an embedded system including multiple system firmware switchable updates and a method for updating between multiple firmwares. Background technique [0002] The functions of electronic products are frequently updated or expanded with the rapid development of technology. Especially for consumer electronic products suitable for embedded systems, they are often updated through firmware, that is, replacing electronic products with newer versions of firmware. The originally applicable firmware is used to correct the functional defects of electronic products, or to increase and strengthen the functions it possesses, so as to enhance the use efficiency of the products. [0003] However, the most common trouble that users encounter when performing firmware updates for embedded systems is accidental operation errors during the update process, or the update proc...
