OpenHarmony 3.2：制作OTA升级包，附脚本及配置开源鸿蒙的OTA包需要手动制作，真是够扯淡的事情。本文介绍手动制作的流程和细节，顺带附了一个简单的OTA打包脚本，基于RK3568。阅读详情

AI摘要

本文围绕OpenHarmony 4.0 release系统，介绍本地OTA升级。先阐述OTA概念、升级方式与包类型，接着详细说明全量包和差分包的制作、升级步骤及验证方法，最后针对升级过程中可能出现的报错给出处理方案，助力工程师完成设备OTA升级调试。

一、环境配置

系统版本：OpenHarmony 4.0 release
设备平台：RK3568

二、OpenHarmony OTA介绍

OTA介绍：
随着设备系统日新月异，用户如何及时获取系统的更新，体验新版本带来的新的体验，以及提升系统的稳定和安全性成为了每个厂商都面临的严峻问题。
OTA（Over the Air）提供对设备远程升级的能力。升级子系统对用户屏蔽了底层芯片的差异，对外提供了统一的升级接口。基于接口进行二次开发后，可以让厂商的设备（如IP摄像头等）轻松支持远程升级能力，即通过移动通信的接口从远程服务器下载新的软件更新包，对自身系统进行升级，从而满足厂商的应用管理需求。
OpenHarmony OTA升级方式：
从OTA包的升级方式来说分为本地升级和网络OTA升级。
- 本地升级：将制作好的OTA包放入设备指定升级路径，在软件相关界面下执行升级或直接输入升级命令进行本地升级。
- 网络OTA升级，设备通过网络从OTA服务器下载OTA包至本地设备，下载完成后在软件相关界面进行升级。
  可以看出本地OTA升级是网络OTA升级的一个环节。通常为了调试方便，验证设备OTA升级可行性，工程师会先进行本地OTA包升级。本文正是介绍OpenHarmony 本地OTA升级步骤。
OTA包类型
从OTA包的类型来说，可分为全量OTA包、差分(增量)OTA包、变分区OTA包。
- 全量OTA升级包：将所有目标版本的镜像均通过全量镜像的方式打包获得的升级包。
- 差分OTA升级包：对源版本和目标版本差分，获得两个版本镜像之间的差异，以这种方式打包制作升级包。
- 变分区OTA升级包：对分区表、镜像全量数据用于变分区处理和变分区后的镜像恢复的升级包。
OTA实现原理：利用升级包制作工具，将编译出的版本打包生成升级包。厂商设备集成 OTA 升级能力后，将升级包上传至服务器，通过升级应用下载升级包，触发并完成升级。
OpenHarmony采用AB升级机制，即设备有一套备份的B系统，在A系统运行时，可以在正常使用的状态下，静默更新B系统，升级成功后，重启切换新系统，实现版本更新的机制。
OpenHarmony OTA升级的约束与限制：
- 支持基于Hi3861/Hi3516DV300/RK3568芯片的开源套件。
- 对Hi3516DV300/RK3568开源套件，设备需要支持SD卡（VFAT格式）。
- 生成升级包需要在linux系统下面执行。
- 目前轻量和小型系统仅支持全量包升级，暂不支持差分包、变分区包升级。
- AB 升级只适用于标准系统支持 AB 分区启动的设备。

三、OTA 全量包制作和本地升级

本章介绍OpenHarmony 4.0 OTA全量包的制作和本地升级步骤。

3.1 OTA 全量包制作

在运行脚本制作OTA包前，先安装必要的工具

$ sudo apt update
$ sudo apt upgrade
$ sudo apt install bsdiff
$ sudo pip install xmltodict asn1crypto imgdiff cryptography e2fsdroid

3.1.1 添加差异（可省略）

为了验证OTA的升级成功与否，可在升级包制作前，对源码添加易于识别的差异，例如：
修改授权管理应用TAG信息
applications/standard/permission_manager/permissionmanager/src/main/ets/ServiceExtAbility/ServiceExtAbility.ts

 import deviceInfo from '@ohos.deviceInfo';
 
-var TAG = "PermissionManager_Log:";
+var TAG = "PermissionManager_Log A:";
 const BG_COLOR = '#00000000'

3.1.2 全量编译，生成images和updater_binary

全量编译源码

$ ./build.sh --product-name=rk3568 --ccache

得到系统镜像文件images和二进制升级文件updater_binary：

images：out\rk3568\packages\phone\images

out/rk3568/packages/phone/images/
├── boot_linux.img
├── chip_prod.img
├── config.cfg
├── MiniLoaderAll.bin
├── parameter.txt
├── ramdisk.img
├── resource.img
├── sys_prod.img
├── system.img
├── uboot.img
├── updater.img
├── userdata.img
└── vendor.img

updater_binary：
3.2 或4.0 release
out\rk3568\packages\phone\system\bin\updater_binary
4.1 release
out\rk3568\packages\phone\updater\bin\updater_binary

3.1.3 制作OTA 全量包

进入OTA打包工具目录,并创建target_package、output_package和sign_cert文件夹

$ cd base/update/packaging_tools
$ mkdir target_package output_package sign_cert

sign_cert放入公钥：signing_cert.crt，取自base/update/updater/test/unittest/test_data/src/signing_cert.crt

target_package放入要打包生成OTA全量包的如下文件

私钥：rsa_private_key2048.pem，取自base/update/updater/test/unittest/test_data/src/rsa_private_key2048.pem
镜像文件：取自out/rk3568/packages/phone/images/
二进制升级文件：updater_binary，
3.2 或4.0 取自out/rk3568/packages/phone/system/bin/updater_binary
4.1 取自out/rk3568/packages/phone/updater/bin/updater_binary
升级组件配置文件夹updater_config，其中放入：
- 升级包支持的产品列表：BOARD.list，取自device/board/hisilicon/hispark_taurus/linux/updater/config/BOARD.list

#BOARD.list 添加一行"RK3568",内容如下：
HI3516
RK3568

注意：HI3516必须有，否则OTA包校验失败而导致OTA升级失败，因为代码匹配BOARD时，固定了默认值：
base/updater/updater/utils/utils.cpp

std::string GetLocalBoardId()
  {
      return "HI3516";
  }

升级包所支持的版本范围：VERSION.mbn，取自device/board/hisilicon/hispark_taurus/linux/updater/config/VERSION.mbn
VERSION.mbn与设置的软件版本保持一致即可：

#VERSION.mbn 内容如下
OpenHarmony 4.0.10.15

组件配置文件：updater_specified_config.xml,取自device/board/hisilicon/hispark_taurus/linux/system/updater_specified_config.xml
- 修改fileVersion为2（4.0更新的校验方式）
- softVersion改为当前软件版本
- compType改为0,表示全量(1 表示增量)
- 修改img打包路径，/vendor.img 和./system.img

<?xml version="1.0"?>
<package>
    <head name="Component header information">
        <info fileVersion="02" prdID="RK3568" softVersion="4.0.10.15" date="2023-08-02" time="16:25">head info</info>
    </head>
    <group name = "Component information">
	<component compAddr="vendor" compId="12" resType="05" compType="0" compVer="1.0">./vendor.img</component>
	<component compAddr="system" compId="18" resType="05" compType="0" compVer="1.0">./system.img</component>
    </group>
</package>

得target_package目录结构如下：

$ tree target_package/
target_package/
├── MiniLoaderAll.bin
├── boot_linux.img
├── chip_prod.img
├── config.cfg
├── eng_system.img
├── parameter.txt
├── ramdisk.img
├── resource.img
├── rsa_private_key2048.pem
├── sys_prod.img
├── system.img
├── uboot.img
├── updater.img
├── updater_binary
├── updater_config
│   ├── BOARD.list
│   ├── VERSION.mbn
│   └── updater_specified_config.xml
├── userdata.img
└── vendor.img

OTA全量包打包命令如下
python3 build_update.py ./target_package/ ./output_package/ -pk ./target_package/rsa_private_key2048.pem

08-05 20:26:14.669 1659-1659/? I A0fefe/JsApp: PermissionManager_Log A:create window

说明全量OTA升级成功且生效。

3.4 异常

若升级失败，重启设备后取出/data/updater/log/updater_log，结合代码进行具体分析。

> hdc file recv /data/updater/log/updater_log C:\Users\xxx\Desktop\ota.log

例如：
现象：OTA全量升级，升级进度条即将跑完时，提示升级失败。
log部分内容如下：

分析：从log可以看出升级至99%时，安装OTA包异常，问题原因是Version Check Fail…，于是检查updater_specified_config.xml和VERSION.mbn，版本信息错位的写为OpenHarmony 4.0.10.14。
解决方案：修改updater_specified_config.xml和VERSION.mbn中版本信息与设备当前软件版本OpenHarmony 4.0.10.13一致，重新制作OTA全量包后升级。

四、OTA差分包制作和升级

4.1、OTA 差分包制作

4.0 release 分支需合入PR
修改组件对应的块错误
base/update/packaging_tools/blocks_manager.py

--- a/blocks_manager.py
+++ b/blocks_manager.py
@@ -27,6 +27,12 @@ class BlocksManager(object):

         elif range_data:
             if len(range_data) % 2 != 0:

4.1.1 添加差异（可省略）

为了方便后续验证差分包升级是否有效，添加差异方便验证：
applications/standard/permission_manager/permissionmanager/src/main/ets/ServiceExtAbility/ServiceExtAbility.ts

 import deviceInfo from '@ohos.deviceInfo';
 
-var TAG = "PermissionManager_Log:";
+var TAG = "PermissionManager_Log B:";
 const BG_COLOR = '#00000000'

4.1.2 全量编译，更新images和updater_binary

全量编译源码

$ ./build.sh -p rk3568 --ccache

得到系统镜像文件images和二进制升级文件updater_binary：

images：out\rk3568\packages\phone\images

out/rk3568/packages/phone/images/
├── boot_linux.img
├── chip_prod.img
├── config.cfg
├── MiniLoaderAll.bin
├── parameter.txt
├── ramdisk.img
├── resource.img
├── sys_prod.img
├── system.img
├── uboot.img
├── updater.img
├── userdata.img
└── vendor.img

updater_binary：
3.2 或4.0 release
out\rk3568\packages\phone\system\bin\updater_binary
4.1 release
out\rk3568\packages\phone\updater\bin\updater_binary

4.2、制作OTA差分包

4.2.1、创建lib文件夹,放入差分镜像二进制工具

packaging_tools$mkdir lib
packaging_tools$cp -rf ../../../out/rk3568/clang_x64/updater/updater/diff lib/
packaging_tools$ cp -rf ../../../out/rk3568/clang_x64/thirdparty/e2fsprogs/* lib/

得到lib文件夹内容如下：

packaging_tools$ tree lib
lib
├── diff		#取自out/rk3568/clang_x64/updater/updater/
├── e2fsck		#及以下.so文件取自out/rk3568/clang_x64/thirdparty/e2fsprogs
├── e2fsdroid
├── libext2_blkid.so
├── libext2_com_err.so
├── libext2_e2p.so
├── libext2_misc.so
├── libext2_quota.so
├── libext2_uuid.so
├── libext2fs.so
└── mke2fs

4.2.2、packaging_tools目录下copy 上一次target_package作为制作差分包的source_package

packaging_tools$ cp -rf target_package/ source_package

更新target_package目录文件

替换镜像文件：

packaging_tools$ cp -rf ../../../out/rk3568/packages/phone/images/* target_package/

替换二进制升级文件：

#3.2 release 或4.0 release
packaging_tools$ cp -rf ../../../out/rk3568/packages/phone/system/bin/updater_binary target_package/updater_binary

#4.1 release
packaging_tools$ cp -rf ../../../out/rk3568/packages/phone/updater/bin/updater_binary target_package/updater_binary

更新target_package/updater_config/updater_specified_config.xml softVersion和compType

#updater_specified_config.xml, 修改softVersion需大于当前系统版本； compType设为1，表示增量；内容如下：
<?xml version="1.0"?>
<package>
    <head name="Component header information">
        <info fileVersion="01" prdID="RK3568" softVersion="4.0.10.16" date="2023-08-02" time="16:25">head info</info>
    </head>
    <group name = "Component information">
	<component compAddr="vendor" compId="12" resType="05" compType="1" compVer="1.0">./vendor.img</component>
	<component compAddr="system" compId="18" resType="05" compType="1" compVer="1.0">./system.img</component>
    </group>
</package>

4.2.3、OTA差分包打包制作

命令如下:
python3 build_update.py ./target_package/ ./output_package/ -s ./source_package/ -pk ./target_package/rsa_private_key2048.pem

得到差分包output_package/updater_diff.zip

4.3 差分包升级

升级方法同全量包，将制作好的差分包updater_diff.zip放入设备，并设置reboot模式

> hdc file send xxx\OHOS\OpenHarmony_v4.0_Release\OTA_Package\output_package\updater_diff.zip /data/updater/updater.zip
FileTransfer finish, Size:315251542, File count = 1, time:35248ms rate:8943.81kB/s

> hdc shell
#write_updater updater /data/updater/updater.zip 
#reboot updater

4.4 验证

使用IDE 过滤“PermissionManager_Log”,结果如下

08-05 20:26:14.659 1659-1659/? I A0fefe/JsApp: PermissionManager_Log B:ServiceExtensionAbility onCreate, ability name is com.ohos.permissionmanager.GrantAbility
08-05 20:26:14.664 1659-1659/? I A0fefe/JsApp: PermissionManager_Log B:ServiceExtensionAbility onRequest. start id is 1
08-05 20:26:14.664 1659-1659/? I A0fefe/JsApp: PermissionManager_Log B:want:

说明增量OTA升级成功且生效。

五、报错处理

5.1、ModuleNotFoundError: No module named ‘xmltodict’

sudo pip install xmltodict

5.2、ModuleNotFoundError: No module named ‘asn1crypto’

sudo pip install asn1crypto

5.3、FileNotFoundError: [Errno 2] No such file or directory: ‘/home/…/OpenHarmony_v4.0_release/base/update/packaging_tools/lib/e2fsdroid’

packaging_tools下创建lib文件夹，放入以下文件

packaging_tools$ tree lib
lib
├── diff		#取自out/rk3568/clang_x64/updater/updater/
├── e2fsck		#及以下.so文件取自out/rk3568/clang_x64/thirdparty/e2fsprogs
