Abstract

The invention discloses an extensible software upgrade method for an embedded terminal, comprising the following steps of: making an upgrade information file into a software upgrade package; choosing an update mode to set up an upgrade environment by the system software of the embedded terminal, and performing software upgrade initialization according to the chosen update mode; and obtaining and verifying the software upgrade package by the system software of the embedded terminal according to the update mode, and performing software upgrade according to update information in the software upgrade package. Via the mode aforementioned, the extensible software upgrade method for the embedded terminal provided by the invention solves the defects of the present software upgrade method for an embedded terminal; software upgrade can be realized for the system software of the embedded terminal via various modes and various ways; the various update needs and update scenes of the system software can be met; and both the burning need of the system software during factory production and a software upgrade requirement during a system maintenance process can be met.

Description

Technical field [0001] The invention relates to the field of maintenance and management software systems, in particular to a method for upgrading an embedded terminal scalability software. Background technique [0002] In order to realize the software upgrade of embedded terminals in different life cycles, general software providers will adopt different software upgrade management mechanisms for the different life cycles of embedded terminals, so as to achieve the purpose of software upgrades for embedded terminals. This management mechanism is more complicated to implement, and the maintenance cost is high. [0003] In Chinese patent 200710052214.3, a wireless remote upgrade method for embedded system software based on file transfer protocol is disclosed. It mainly adopts equipment terminal management center, file transfer protocol server and embedded terminal. It adopts file transfer protocol and uses mobile universal Packet wireless service technology or Unicom's code division ...
