Abstract

In a method for adapting a firmware configured to control a wireless communication device, a first firmware is stored in a first storage area, and at least one delta encoding package is stored in at least one second storage area. A rule manager is configured to provide identification information indicating at least one delta encoding package. Bootstrap software is configured to, upon startup, retrieve the first firmware from the first storage area, retrieve from the rule manager identification information indicating at least one delta encoding package retrieve the indicated at least one delta encoding package from the second storage area, combine said first firmware and the at least one delta encoding package to a second firmware by way of a differential upgrade, and start the second firmware.

Claims15

Dependent claims

Method for adapting a firmware configured to control a wireless communication device, the wireless communication device comprising at least one storage unit, a bootstrap software and a rule manager wherein a first firmware is stored in a first storage area, the first storage area being part of the at least one storage unit, at least one delta encoding package is stored in at least one second storage area, the second storage area being part of the at least one storage unit, and the rule manager is configured to provide identification information indicating at least one delta encoding package, the method comprising the steps, for the bootstrap software:

upon startup retrieving the first firmware from the first storage area,
retrieving from the rule manager identification information indicating at least one delta encoding package
retrieving the indicated at least one delta encoding package from the second storage area,
combining said first firmware and said at least one delta encoding package to a second firmware by way of a differential upgrade, and
starting said second firmware.
