编译指令
发布一个固件正确的顺序
1、make -j32
2、make otapackage -j32
3、./mkimage.sh ota
4、./build.sh -u
或者直接执行
make -j32 && make otapackage -j32 && ./mkimage.sh ota && ./build.sh -u
拷贝 rockdev\Image-RK3326Box\update.img 作为发放烧写软件包
直接用 AndroidTool_Release 烧写固件即可
整包升级
拷贝 \out\target\product\RK3326Box\RK3326Box-ota-eng.zip 作为完整升级包，
重命名为 update.zip 拷贝到设备SDCard卡根目录重启，RKUpdateService-box 应用会弹框提示升级
差分包升级
拷贝 out\target\product\RK3326Box\obj\PACKAGING\target_files_intermediates\RK3326Box-target_files-eng.zip
为 V1.zip，作为 V1 版本的基础素材包备用，拷贝至源码根目录
修改kernel、package等 新版本修改内容后再次执行编译指令
make -j32 && make otapackage -j32 && ./mkimage.sh ota && ./build.sh -u
拷贝 out\target\product\RK3326Box\obj\PACKAGING\target_files_intermediates\RK3326Box-target_files-eng.zip
为 V2.zip，作为 V2 版本的基础素材包备用，拷贝至源码根目录
编译生成差分包指令
./build/tools/releasetools/ota_from_target_files -v -i V1.zip --block -p out/host/linux-x86 -k build/target/product/security/testkey V2.zip update.zip
更目录下的 update.zip 就是最终的差分升级包
生成差异包命令格式:
ota_from_target_files
-v -i 用于比较的前一个 target file
–block 使用 block 方式进行 OTA 升级，Android 版本>=7.1 时需加上这个参数
-p host 主机编译环境
-k 打包密钥 用于比较的后一个 target file 生成的 ota 差异包
调用系统升级API RecoverySystem.installPackage

错误排查
完整包并未遇到该问题
在升级差分包时，出现了上图所示的错误
错误代码
E3001 this device has unknown/RK3326Box/…:userdebug/test-keys
E:Error in @/cache/recovery/block.map(status 7)
开始其实提示的是 E3001 this device has unknown/RK3326Box/…:userdebug/release-keys
去签名文件夹下中寻找 \build\target\product\security 确实没有 releasekey 相关
于是猜想和这里有关系，修改编译使用 test-keys
build/make/core/Makefile
ifeq ($(TARGET_BUILD_VARIANT),eng) BUILD_KEYS := test-keys else -BUILD_KEYS := release-keys +# BUILD_KEYS := release-keys +BUILD_KEYS := test-keys endif BUILD_VERSION_TAGS += $(BUILD_KEYS)
编译后可以通过 out\target\product\RK3326Box\system\build.prop 文件中 ro.system.build.tags=test-keys 确认
再次烧写ota升级验证，发现问题依旧，仔细品了品错误提示后发现 build fingerprint 这个关键字
机智的我立马去和 8.0 的 build.prop 进行了对比，最终发现差异
Q 版本
ro.system.build.fingerprint=rockchip/RK3326Box/RK3326Box:10/QQ2A.200501.001.B3/09021634:userdebug/test-keys
O版本
ro.build.fingerprint=rockchip/rk3288/rk3288:8.1.0/OPM8.190305.001/133946:userdebug/test-keys
Q版本中不存在 ro.build.fingerprint 字段，会不会和这有关系呢？先加上试试吧
搜索 ro.system.build.fingerprin 发现在 build/make/tools/buildinfo_common.sh 中进行写入
我们新增一条 ro.build.fingerprint
+++ b/build/make/tools/buildinfo_common.sh @@ -13,6 +13,7 @@ echo "# autogenerated by $0" echo "ro.${partition}.build.date=`$DATE`" echo "ro.${partition}.build.date.utc=`$DATE +%s`" echo "ro.${partition}.build.fingerprint=$BUILD_FINGERPRINT" +echo "ro.build.fingerprint=$BUILD_FINGERPRINT" echo "ro.${partition}.build.id=$BUILD_ID" echo "ro.${partition}.build.tags=$BUILD_VERSION_TAGS" echo "ro.${partition}.build.type=$TARGET_BUILD_TYPE"
再次重新编译烧写ota问题解决，升级成功啦！
