一、adb 本地测试升级错误

解决：注意命令格式

update_engine_client  --payload=file:///sdcard/payload.bin --update --headers="FILE_HASH=QlyQnyZ6LOC9gjyXTvWxOLC/kO9xuL/+h6tXzF6zHD8=
FILE_SIZE=24549898
METADATA_HASH=j+I7TEKTuAsIqhryaBxWkQlVw/NoHWxT7uMTTpuUMSE=

二、差分升级错误

解决：out 下img不做发布版本

刷机不刷out下，而是刷out/target/product/xxx_8q/obj/PACKAGING/target_files_intermediates/xxx_8q_car2-target_files-eng.win/IMAGES/下镜像
