一、 ota差分包制作命令及结果如下：
packaging_tools\$ python3 build_update.py ./target_package/ ./output_package/ -s ./source_package/ -pk ./target_package/rsa_private_key2048.pem

三、target_package和source_package对比差异如下：
diff target_package/ source_package/
Binary files target_package/boot_linux.img and source_package/boot_linux.img differ
Binary files target_package/chip_prod.img and source_package/chip_prod.img differ
Binary files target_package/eng_system.img and source_package/eng_system.img differ
Binary files target_package/ramdisk.img and source_package/ramdisk.img differ
Binary files target_package/resource.img and source_package/resource.img differ
Binary files target_package/sys_prod.img and source_package/sys_prod.img differ
Binary files target_package/system.img and source_package/system.img differ
Binary files target_package/updater.img and source_package/updater.img differ
Common subdirectories: target_package/updater_config and source_package/updater_config
Binary files target_package/userdata.img and source_package/userdata.img differ
Binary files target_package/vendor.img and source_package/vendor.img differ
packaging_tools$ diff target_package/updater_config/ source_package/updater_config/
diff target_package/updater_config/updater_specified_config.xml source_package/updater_config/updater_specified_config.xml
