RK3229平台Android6.0系统添加广升OTA升级功能

1. 添加脚本：

build/core/FotaInfo.sh

#!/bin/bash

#********Do not modify this file. If you want modify this file, pls contact our FAE*******
echo ""
echo "# begin fota properties"
echo "ro.fota.platform=RK3229"
#type info: phone, pad ,box, tv
echo "ro.fota.type=hifi"
#oem info
echo "ro.fota.oem=CompanyName " #广升备案的公司名称
#model info, Settings->About phone->Model number
#FotaDevice=$(grep "ro.product.model=" "$1"|awk -F "=" '{print $NF}' )
#echo "ro.fota.device=SK04$FotaDevice" | sed  's/[^0-9a-zA-Z= ._-]//g'
echo "ro.fota.device=SK04"
#version number, Settings->About phone->Build number
#FotaVersion=$(grep "ro.build.display.id=" "$1"|awk -F "=" '{print $NF}' )`date +_%Y%m%d-%H%M`
FotaVersion=$(grep "ro.build.display.id=" "$1"|awk -F "=" '{print $NF}' )
echo "ro.fota.version=$FotaVersion"
echo "# end fota properties"
#********Do not modify this file. If you want modify this file, pls contact our FAE*******

cd ..
mv target_files-package/target_files-package.zip $1/target_files-package.zip
rm -rf target_files-package

2.修改Makefile

build/core/Makefile

……//此处省略好多行
#abupdate fota start
ifeq ($(strip $(ABUPDATE_FOTA_SUPPORT)), yes)
FOTA_SH := build/core/FotaInfo.sh
endif
#abupdate fota end
BUILDINFO_SH := build/tools/buildinfo.sh
……//此处省略好多行
#abupdate fota start
ifeq ($(strip $(ABUPDATE_FOTA_SUPPORT)), yes)
        @echo "Target FotaInfo: $@"
        $(hide) chmod 777 $(FOTA_SH)
        bash $(FOTA_SH) $@ >> $@
endif
#abupdate fota end

build_desc :=

ifeq (,$(filter true, $(TARGET_NO_KERNEL) $(TARGET_NO_RECOVERY)))
INSTALLED_RECOVERYIMAGE_TARGET := $(PRODUCT_OUT)/recovery.img
else
INSTALLED_RECOVERYIMAGE_TARGET :=
Endif
……//此处省略好多行
#abupdate fota start
ifeq ($(strip $(ABUPDATE_FOTA_SUPPORT)), yes)
        @echo "Package FotaPackage"
        $(hide) chmod 777 build/core/getOtaPackage.sh
        bash build/core/getOtaPackage.sh $(PRODUCT_OUT) $(KEY_CERT_PAIR) $(TARGET_DEVICE) $(HOST_LIBRARY_PATH) $(HOST_SHLIB_SUFFIX)
endif
#abupdate fota end

.PHONY: otapackage
otapackage: $(INTERNAL_OTA_PACKAGE_TARGET)
……//此处省略好多行

3.修改BoardConfig.mk:

device/rockchip/rk322x/BoardConfig.mk

……//此处省略好多行
#abupdatefota start
ABUPDATE_FOTA_SUPPORT = yes
#abupdatefota end

4.最后修改根目录下的总编译脚本build_all.sh:

在make -j16之后添加

# build otapackage
echo "start build otapackage"
cd build/tools/drmsigntool && mm -B && cd -
make otapackage
# mkimage.sh
echo "make and copy android images"
# Note:it is neccessary to add ota.
./mkimage.sh ota

5.以上都做完之后每次全编译代码会生成OTA整包文件：target_files-package.zip，两个版本之间的整包通过广升提供的工具（IOTdeltaTool2.0.0.5_2018.3.23.zip）就可以做差分包了，最后在服务器上配置差分升级即可。

 

注意：

1）. IOTdeltaTool2.0.0.5_2018.3.23.zip需要解压，然后在JDK1.8上通过指令（java -jar IOTdeltaTool2.0.0.5.jar）来运行。

2）. 运行中可能存在环境错误，这时需要再安装（adups-delta-5.0.24.deb）

sudo dpkg -i adups-delta-5.0.24.deb
