METHOD, SYSTEM AND APPARATUS FOR REMOTE SOFTWARE UPGRADE OF AN EMBEDDED DEVICE

摘要

A system, method and apparatus for iemote upgi ade of the softw are of an embedded dev ice supporting packet-based communication. A packet-based communication path ts prov ided betw een a iemote device and the embedded dev ice. An intermediate dev ice is placed in the packet-based communication path as a local node directly coupled to the embedded dev ice The intermediate dev ice includes packet forvv aiding means for cairying out normal communication between the remote dev ice and the embedded dev ice The softw are of the embedded device is upgraded bv i) ti ansferpng softwaie upgrade data fiom the remote device to the intermediate device, ii) transferring the software upgrade data from the intermediate dev ice to the embedded device, and in) carrying out an upgrade process on the embedded dev ice that loads the software upgrade data on the embedded device
