Abstract
A method of installing a software application image, for a software upgrade, within a remote and embedded target device includes the step of storing both a current and an upgraded software application image within an EEPROM within the target device. The set of instructions embodied within the current application image is maintained within the target device, while a validation operation is performed with respect to a set of instructions embodied within the upgraded software application image. Only once complete installation and successful execution of the upgraded application image have been validated is the upgraded application image designated as a current application image, and the previously installed application image discarded. Accordingly, the risk of the target device being a rendered unbootable as a result of the installation of a software upgrade is reduced.
