开始之前
给radxa rock编译AOSP(Android Open Source Project)整个安卓系统源码是一项大工程,会很耗费时间和硬盘空间。你可以参考安卓官方的详细系统要求页面。推荐的编译主机是Ubuntu 12.04 64位。在我们的测试编译机器上一次完整编译总共花费了35分钟和30G的硬盘空间。配置Intel 4770处理器(第四代i7,四核八线程,3.4Ghz),16G内存和256G固态硬盘(友情提示: 固态硬盘可以极大提高编译速度).
初始化编译环境
参考了安卓官方的环境搭建教程,下面是我们测试过的在全新的系统上可用的步骤。
- 安装JDK
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java6-installer
- 安装所需要的包
sudo apt-get install git gnupg flex bison gperf build-essential \ zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \ libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \ g++-multilib mingw32 tofrodos gcc-multilib ia32-libs\ python-markdown libxml2-utils xsltproc zlib1g-dev:i386
注意: 在Ubuntu 13.10上,已经没有ia32-libs这个包,不需要安装这个包。
- 安装ARM交叉编译器和编译内核相关依赖
sudo apt-get install gcc-arm-linux-gnueabihf sudo apt-get install lzop libncurses5-dev export ARCH=arm export CROSS_COMPILE=arm-linux-gnueabihf-
- 安装其他所需要的运行库
sudo apt-get install libssl1.0.0 libssl-dev
获取源码
wget http://dl.radxa.com/rock/source/radxa_rock_android.tar.gz #(也可以从: 百度云下载) tar zxf radxa_rock_android.tar.gz cd radxa_rock_android git checkout .
或者如果你能访问git服务器,可以以下命令获取代码:
git clone -b radxa-dev git@git.linux-rockchip.org:radxa/radxa_rock_android.git cd radxa_rock_android
注意: 如果有人知道怎么把这个大的代码仓库推送到github,让我们知道(写邮件到support@radxa.com)。我们因为大文件问题,不能推到github,尝试了各种方式均未成功。
编译内核
export ARCH=arm cd kernel make rk3188_radxa_rock_defconfig #Use this config If you build the android 4.2 JB image for radxa rock make rk3188_radxa_rock_kitkat_defconfig #Use this config If you build the android 4.4 KK image for radxa rock make rk3188_box_radxa_rock_pro_hdmi_defconfig #Use this config if you build the android 4.4 KK image for radxa rock pro make rk3188_box_radxa_rock_lite_hdmi_defconfig #Use this config if you build the android 4.4 KK image for radxa rock lite make kernel.img #kernel.img is the normal kernel image with rockchip crc cd ..
编译安卓源码
source build/envsetup.sh lunch rk31sdk-eng #Launch this config if you build android 4.2 JB for radxa rock lunch radxa_rock-eng #Launch this config if you build android 4.4.2 KK for radxa rock lunch radxa_rock_pro-eng #Launch this config if you build android 4.4.2 KK for radxa rock pro lunch radxa_rock_lite-eng #Launch this config if you build android 4.4.2 KK for radxa rock lite make -j8
生成镜像
./mkimage.sh ota
你会在rockdev/Image文件夹下得到boot.img recovery.img system.img分区镜像文件, 和 rockdev文件夹下的 update.img整个固件。
写入镜像(刷机)
参考rock/flash the image如何刷入你刚刚编出来的镜像。
