制作ota包
. build/envsetup.sh
lunch [product]
make -j8
make otapackage -j8
cp out/target/product/projectname/obj/PACKAGING/target_files_intermediates/projectname-target_file-xxxx.zip ota/A.zip
修改代码,已显示版本有更新：
重新走一边
. build/envsetup.sh
lunch [product]
make -j8
make otapackage -j8
cp out/target/product/projectname/obj/PACKAGING/target_files_intermediates/projectname-target_file-xxxx.zip ota/B.zip
然后制作OTA差分包
没有签名的差分包
python build/tools/releasetools/ota_from_target_files.py -i ota/A.zip ota/B.zip ota/update.zip
有签名的差分包
python build/tools/releasetools/ota_from_target_files.py -k device/fsl/common/security/platform -i ota/A.zip ota/B.zip ota/update.zip
有签名的差分包且打印执行输出记录
python build/tools/releasetools/ota_from_target_files.py -k device/fsl/common/security/platform -v -i ota/A.zip ota/B.zip ota/update.zip
