【求助】OpenHarmony 4.0 OTA 本地升级失败（已解决）

虽然网上OHOS OTA包制作和升级资料有一些，但大多是基于hi3516或3.2 beta3，并且缺少细节步骤和修改，拜读了多位大佬的文章，经过多次尝试OTA仍升级失败，还望了解OpenHarmony OTA的老哥指点指点~ 我的详细操作步骤如下： OpenHarmony 软件版本：OpenHarmo

虽然网上OHOS OTA包制作和升级资料有一些，但大多是基于hi3516或3.2 beta3，并且缺少细节步骤和修改，拜读了多位大佬的文章，经过多次尝试OTA仍升级失败，还望了解OpenHarmony OTA的老哥指点指点~

我的详细操作步骤如下：

OpenHarmony 软件版本：OpenHarmony 4.0.9.6

平台：RK3568

1、下拉4.0 beta2 版本代码后，全量编译得到基准版本软件A，并烧录images。

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

2、修改部分源码，方便验证OTA升级成功。修改后删除/out，重新全量编译，得到用于制作OTA包的images

applications\standard\permission_manager\permissionmanager\src\main\ets\ServiceExtAbility\ServiceExtAbility.ts

- const TAG = 'PermissionManager_Log: ';

+ const TAG = 'PermissionManager_Log B: ';

3、制作OTA包

参考官方资料：https://docs.openharmony.cn/pages/v3.2/zh-cn/device-dev/subsystems/subsys-ota-guide.md/#%E6%A0%87%E5%87%86%E7%B3%BB%E7%BB%9F%E5%8D%87%E7%BA%A7%E5%8C%85%E5%88%B6%E4%BD%9C

3.1 拷贝device/board/hisilicon/hispark_taurus/linux/updater/config/rsa_private_key2048.pem至base/update/packaging_tools/

在base/update/packaging_tools/下创建sign_cert文件夹，并拷贝device/board/hisilicon/hispark_taurus/linux/updater/config/signing_cert.crt至base/update/packaging_tools/sign_cert/

packaging_tools$ tree

├── ...
├── rsa_private_key2048.pem
├── sign_cert
│   └── signing_cert.crt
├── ...

3.2 在base/update/packaging_tools/下创建target_package和output_package文件夹。在target_package中创建updater_config文件夹

target_package文件夹内容如下：

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

1 directory, 18 files

其中：

> *img 和*.cfg取自上一步骤编译生成的镜像文件：out/rk3568/packages/phone/images/

> updater_binary 二进制升级文件取自上一步骤生成的镜像文件：out/rk3568/packages/phone/system/bin/

> updater_config/BOARD.list取自device/board/hisilicon/hispark_taurus/linux/updater/config/BOARD.list,内容改为：

HI3516
RK3568

updater_config/VERSION.mbn取自device/board/hisilicon/hispark_taurus/linux/updater/config/VERSION.mbn，内容改为：

OpenHarmony 4.0.9.6

updater_config/updater_specified_config.xml取自device/board/hisilicon/hispark_taurus/linux/system/updater_specified_config.xml，内容改为：

<?xml version="1.0"?>
<package>
    <head name="Component header information">
        <info fileVersion="01" prdID="123456" softVersion="OpenHarmony 4.0.9.6" date="2021-03-11" time="12:30">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>

3.3 在base/update/packaging_tools/目录下执行以下命令生成OTA全量包

packaging_tools$ python3 build_update.py ./target_package/ ./output_package/ -pk ./rsa_private_key2048.pem

得到OTA全量包base/update/packaging_tools/output_package/updater_full.zip,解压后包含：

board_list、build_tools.zip、update.bin、version_list

4、升级OTA包

将生成的OTA包通过hdc 放入设置data/updater/下

$ hdc file send xxx\OHOS\OpenHarmony_v4.0_beta2\base\update\packaging_tools\output_package\updater_full.zip /data/updater/

进入hdc shell启动OTA升级

$ hdc shell
# write_updater updater /data/updater/updater_full.zip
# reboot updater

升级失败，重启设备后，查看/data/updater/log/updater_log，报错如下Failed to memcmp data.
