hi all,
i have existing old version images like kernel image,filesys image,application images in my NAND flash. i want to port the new modified kernel and application image on to the NAND flash by replacing the older one. But in the new images 90% is common to the old images. so i don't want the entire new image to transfer. inspite i am thinking of some kind of comaprision between the old and new images and want to send only the difference on to flash memory. so that i can avoid transfering a larger data.
can it be possible ? i need some guidence to do this.
