概述
OTA(空中下载技术)是一项在线升级技术，它允许终端设备通过网络从服务器下载系统固件并进行升级。高可靠OTA是RK在OTA的基础上增加了两个备份分区实现的一套高可靠的OTA升级机制，其高可靠表现在由于意外情况（断电、固件问题、机器故障）导致升级失败的情况下，仍然可以使用备份分区开机，再次进行升级，避免了升级变砖的情况。
先简要介绍普通OTA,然后介绍高可靠OTA
普通OTA
步骤1.配置版本号及更新服务器
device/rockchip/rk3399/rk3399_mid_pi.mk
diff --git a/rk3399_mid_pi.mk b/rk3399_mid_pi.mk

endif
步骤2. 编译ota固件
//仅编译android固件
source build/envsetup.sh
lunch 9
make
make otapackage
./mkimage.sh ota
//全编译
//uboot
cd u-boot
make rk3399_defconfig
make ARCHV=aarch
//kernel
cd kernel
make ARCH=arm64 qxzn_onfig
make ARCH=arm64 rk3399-mid-pi.img
//android
source build/envsetup.sh
lunch 9
make
//ota
make otapackage
./mkimage.sh ota
步骤3. 修改版本，编译差异包
差异包生成脚本：
./build/tools/releasetools/ota_from_target_files --block -v -i rockdev/ota_package/orignal/rk3399-target_files-v1.0.0.zip -p out/host/linux-x86 -k build/target/product/security/testkey rockdev/ota_package/orignal/rk3399-target_files-v1.0.1.zip rockdev/ota_package/diff/rk3399-v100-v101.zip
原始包路径（用于生成差异包的素材包）：
out/target/product/rk3399_mid_pi/obj/PACKAGING/target_files_intermediates
ota升级整包路径（用于整包升级）：
out/target/product/rk3399_mid_pi
注意：
- 重新编译时要修改版本号
- 重新编译时要删除out/target/product/rk3399_mid_pi/system/build.prop 文件
- 重新编译时要删除out/target/product/rk3399_mid_pi/obj/PACKAGING 目录
步骤4. 烧录烧录基准ota包
使用RK提供的烧录工具即可.注意:不要单独烧kernel.img，否则无法进行差分升级。
步骤5. 固件升级(本地测试)
将固件（整包或差分包）改名为update.zip，放到机器用户根目录，即可自动检测升级（插拔typec或重启）。
高可靠OTA
步骤1.打开高可靠功能配置

+HIGH_RELIABLE_RECOVERY_OTA := true
BOARD_USES_FULL_RECOVERY_IMAGE := false
注意：不建议打开BOARD_USES_FULL_RECOVERY_IMAGE;该宏可能会导致高可靠OTA差分包制作失败。
步骤2.制作parameter_hrr.txt高可靠分区文件

相较于普通parameter.txt文件,增加了uboot_ro和trust_ro分区.后面分区的起始地址都要做相应的增加.
步骤3.生成uboot_ro.img
合入补丁

+ board_fbt_run_recovery();
+ #endif
}
}
然后编译，编译成功后将 uboot.img 修改为 uboot_ro.img
注意：移植完成高可靠OTA之后，每次在u-boot目录进行提交都需要重新生成uboot_ro.img。这样才能保证备份分区和主分区代码一致。
步骤4. 去掉前面生成 uboot_ro 的补丁修改;将高可靠升级的 miniloader放置在 u-boot/ tools/rk_tools/bin/rk33/目录下(miniloader需要向RK申请)
打上loader的patch

步骤五:重新编译uboot即可生成支持高可靠OTA的uboot.img
注意：
-
不同SDK和主板miniloader可能不同，在源码路径的放置也可能不同。具体可以参考SDK中的《高可靠OTA使用说明文档.pdf》
-
步骤四不是必须的，如果不打build_tools的patch 也可以正常生成OTA整包和差分包，那么就不需要执行步骤四。
其余步骤同普通OTA.
固件无法单独烧录Kernel
实现了高可靠OTA之后,测试时单独编译kernel并烧录可能出现问题,可以采用如下补丁规避.
