Abstract

A method and apparatus of updating an embedded software operative in a digital device by a software patch comprises first preparing said embedded software. The method comprises designating at least one Flash block of a Flash memory in said digital device as Flash update block for software update programming, designating at least one area in RAM memory in said digital device as RAM update buffer for Flash programming, preparing Flash erasing function and Flash writing function, designating a memory area in said digital device as patch area, loading said embedded software into said digital device. The method then comprises generating a software patch, adapted to provide a predetermined function, transmitting said software patch to said digital device through a communications link, receiving said software patch by said digital device, updating at least one Flash block of said embedded software in the unit of Flash block with said software patch.
