Abstract
Systems and methods for performing firmware update on an embedded system by patching. In operation, a computing device may receive an image of replacement firmware, which is a different version of current firmware stored in a non-volatile memory of the embedded system. The computing device then determines the different portions of the replacement firmware from the current firmware by comparing the image of the replacement firmware to the current firmware, and retrieves the different portions from the image of the replacement firmware to form the fragments. In this case, the computing device may create a patch file by data of the fragments, and send the patch file to the embedded system, such that the embedded system may use the patch file to update the current firmware. The size of the patch file would be relatively smaller than the firmware image, thereby reducing update time and resources consumption.
