在启用了 A/B 的设备上，可以在后台对应用进行编译，以更新到新的系统映像。如需在系统映像中选择性地加入编译脚本和二进制文件，请参阅在后台编译应用。

设置编译变量

支持 A/B 更新的引导加载程序必须满足以下编译变量条件:

必须针对 A/B 更新目标定义的变量

  • AB_OTA_UPDATER := true
  • AB_OTA_PARTITIONS :=
    boot
    system
    vendor
  • 以及通过 update_engine 更新的其他分区（无线装置、引导加载程序等）。
  • BOARD_BUILD_SYSTEM_ROOT_IMAGE := true
  • TARGET_NO_RECOVERY := true
  • BOARD_USES_RECOVERY_AS_BOOT := true
  • PRODUCT_PACKAGES +=
    update_engine
    update_verifier
  • 要查看示例，请参阅 /device/google/marlin/+/android-7.1.0_r1/device-common.mk。 您可以选择执行编译中所述的安装后（但在重新启动前）dex2oat 步骤.

无法针对 A/B 目标定义的变量:

  • BOARD_RECOVERYIMAGE_PARTITION_SIZE
  • BOARD_CACHEIMAGE_PARTITION_SIZE
  • BOARD_CACHEIMAGE_FILE_SYSTEM_TYPE

可选 针对调试版本定义的变量

PRODUCT_PACKAGES_DEBUG += update_engine_client

(节选) 非GMS版本需要客户端

  • GmsCore 起到什么作用？
    在 Google 的 A/B 实现中，平台 API 和 update_engine 负责提供机制，而 GmsCore 则负责提供政策。也就是说，平台知道如何应用 A/B 更新，并且所有相应代码都位于 AOSP 中（如上所述），而 GmsCore 则负责确定应用哪些内容以及何时应用。
    如果不使用 GmsCore，则可以使用相同的平台 API 编写自己的替代项。用于控制 update_engine 的平台. Java API 是 android.os.UpdateEngine：frameworks/base/core/java/android/os/UpdateEngine.java。调用程序可以提供 UpdateEngineCallback，以便接收有关状态更新的通知：frameworks/base/+/master/core/java/android/os/UpdateEngineCallback.java。请参阅核心类的参考文件，了解如何使用相应接口。

AB 升级过程调试

先制作ota升级包 make otapackage -j4
制作完成的升级包, 解压出payload.bin和payload_properties.txt
将升级包push到手机中, 执行命令:

logcat抓取update_engine的log, 发现报错:

adb root;adb disable-verity;adb reboot;adb root;adb remount;
adb push system/bin/update_engine  /system/bin/
adb shell;
stop update_engine; start update_engine;

发现该处log比较奇怪:

1
07-23 16:59:54.693  5879  5879 I update_engine: [0723/165954.693766:INFO:install_plan.cc(83)] InstallPlan: new_update, version: , source_slot: A, target_slot: B, url: file://stroage/emulated/0/payload.bin, payload: (size: 0, metadata_size: 0, metadata signature: , hash: , payload type: unknown), hash_checks_mandatory: true, powerwash_required: false, switch_slot_on_reboot: true, run_post_install: true

dump的地方在update_attempter_android.cc文件中install_plan_.Dump();

最后调试下来发现是参数格式不对, 正确的应该这样写:

注意换行符的写入方式

在上面的尝试后, 发现本地地址不能解析
需要在本地电脑上架设小型服务器,

#在升级包路径下执行
python -mSimpleHTTPServer
python -m http.server  #python3

传入的参数为:

最后发现本地地址也是可以解析的, 只是路径名要写对:

1
--payload=file:///storage/emulated/0/payload.bin

注意file:后面三个’/‘, 前两个是file的scheme, 后一个代表的是手机的根路径

上面的分区和有b分区的比下来, 除了logo, 其他的都要升级, 注意跟多出来的b分区的对比, 少了一个分区是multiimgoem, 对应的镜像multi_image.mbn

原生打包的方式

先看下AB_OTA_PARTITIONS的作用范围
META/ab_partitions.txt
现有逻辑是查device/board下定义的AB_OTA_PARTITIONS, 将扫到的分区写到target-files的这个文件中
由/system/update_engine/scripts/brillo_update_payload的generate生成对应的payload.bin
该文件为shell脚本, 编译时会被拷贝到/out/host/linux-x86/bin下面
原生方式只识别后缀名为.img的镜像文件, 在add_img_to_target_files制作target-files时, 会将RADIO目录下的后缀为.img的镜像文件拷贝到IMAGES下.
由brillo_update_payload脚本根据IMAGES下的镜像文件和ab_partitions.txt文件中的升级分区生成对应的升级包

firmware的相关修改

将firmware加到升级序列时, 有下面几个问题要解决

a. firmware的大部分镜像都不是img后缀结尾的

b. 需要按board按需添加对应的firmware, 最好不要写死

c. firmware的镜像放在RADIO而非IMAGES下, 这点有正式签名的考虑.(正式包会在Makefile执行完成后, 对做出的target-files下的IMAGES目录下的文件进行删除, 重新生成并签上正式签名), 因此不宜将firmware的镜像仿照原生逻辑直接拷贝到IMAGES下

d. firmware的镜像大部分跟其对应的分区名称名字不是对应的.

综上几点, 考虑的修改方式为:

  1. 复用Board下的filesmap文件, 该文件定义了firmware镜像跟分区名称的对应规则, 该文件已经被打包到target-files下的RADIO目录下
  2. ab_partitions的firmware的添加规则和原生的区分, 原生的是在宏AB_OTA_PARTITIONS下添加的, firmware的加入时机直接在add_img_to_target_files中对AB的操作时触发. 因RADIO目录下的文件已经是按board需要添加的, 可以直接扫描RADIO目录的文件, 且与filesmap文件中对应的即为所要升级的分区. (主要排除掉没有b slot的分区), 追加到META/ab_partitions.txt文件中.
  3. 由于上面的d项, 分区名跟镜像名不对应, 这里复用filesmap文件, 添加分区名跟镜像名的映射map, 写入到META/ab_partitions_map.txt文件中
  4. brillo_update_payload脚本中修改, 将只从IMAGES中和分区名和镜像名严格匹配的规则修改, 变更为除去IMAGES中已知的分区, 其他按照META/ab_partitions_map.txt的对应规则从RADIO目录取镜像文件.

重启手机查看是否切换了slot

1
`fastboot getvar current-slot`

fastboot 手动切换slot

1
`fastboot set_active a|b`

在主系统下查看是否已经切换了slot:

可以通过mount查看挂载的是否是对应slot的分区, 也可以重新执行update_engine_client查看source slot.

其他的fastboot相关命令和变量:

  • has-slot:<partition-base-name-without-suffix>：如果指定分区支持插槽，则返回“yes”，否则返回“no”。
  • current-slot：返回接下来将从中启动的插槽后缀。
  • slot-count：返回一个表示可用插槽数量的整数。目前支持两个插槽，因此该值为 2。
  • slot-successful:<slot-suffix>：如果指定插槽已标记为成功启动，则返回“yes”，否则返回“no”。
  • slot-unbootable:<slot-suffix>：如果指定插槽被标记为不可启动，则返回“yes”，否则返回“no”。
  • slot-retry-count：启动指定插槽的剩余重试次数。

recovery升级X_slot

recovery借助update_engine_sideload进行AB系统的升级, 过程与主系统中的大体类似, 跳过hidl服务直连hal的静态库.

适配时需要将bootctl的hal的静态库接入update_engine_sideload.

# Enable update engine sideloading by including the static version of the

PRODUCT_STATIC_BOOT_CONTROL_HAL := \
    bootctrl.msmnile \
    librecovery_updater_msm \
    libz \
    libcutils

PRODUCT_PACKAGES += \
    update_engine_sideload

qcom的bootctrl.msmnile库并没有静态版本, 将其改造成静态版本, 同时注意platform的binary不能访问vendor的静态库, 需要去掉vendor属性
