Abstract
The present invention provides a firmware update technique in which a work area is small, a work time is short, update can be resumed even if power-down occurs, and even a file system which does not support writing is supported. To provide the firmware updating technique, an update creating and distributing server divides old and new version firmware images, extracts a difference between the new and old divided firmware images, creates an updated package, and delivers the updated package to an embedded device. On the other hand, the embedded device applies the updated package to the old version divided firmware image (an existing firmware message currently in use).
