openharmony 3.2 release ota升级
一、环境说明
- 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
- 1
- 2
- 3
- 4
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
- 4
- 5
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
- 1
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

- updater_binary：out\rk3568\packages\phone\system\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
- 1
- 2
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，取自out/rk3568/packages/phone/system/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
- 1
- 2
- 3
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";
}
- 1
- 2
- 3
- 4
- 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
- 1
- 2
- 组件配置文件：updater_specified_config.xml,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
- 修改
<?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>

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。

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
- 1
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/
- 1
- 替换二进制升级文件：
packaging_tools$ cp -rf ../../../out/rk3568/packages/phone/system/bin/updater_binary target_package/updater_binary
- 1
- 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>
