Abstract
The present invention reduces the time required to apply an update package for generating a new image from an original image within a non-volatile memory device by effectively reducing the number of flash blocks requiring modification by use of whatever free space is available at the end of the image as required. A set of software development guidelines and an improved firmware development tool chain (i.e. compiler, linker, etc.) are utilized to produce new firmware for the client device. A firmware programmer follows or applies this set of guidelines when developing new features and fixes for distribution via a new firmware image. The improved firmware development tool chain executes on a collection of function blocks, available from the development of the original image, used to create new firmware source code, which when complied and linked yields a new image, prior to the delta or differencing processing.
