Abstract

The method (50) involves obtaining a virtual memory image (500). A mapping function is established (501) to determine each virtual memory address of information blocks of the image and a physical memory address associated with a virtual memory address, where each block is sent by a reprogramming tool (20) with an indication of the virtual memory address to which the block to be written. The physical memory address to which the block to be written is determined (523) for the block received by an electronic controller (10), according to the mapping function. An independent claim is also included for an information storage medium comprising a set of instructions for reprogramming a non-volatile rewriteable memory of an electronic controller.
