OTA in Android is applicable to boot.img and system.img. I just tried to add my u-boot.bin within the OTA Package by following the steps under the topic "How do I customize the update script to update uboot?" in Android_Frequently_Asked_Questions.pdf guide. But I couldnt locate the script 'make_update_zip.sh' . Where is this script available? or Is there any alternative method to include u-boot with in a OTA package.
