Rock/Android Build
Contents
Before start
Building AOSP(Android Open Source Project) for radxa rock is a huge task, it takes a lot of time and disk space. You can read the detail requirement of the machine on AOSP requirement page. The recommend building OS is Ubuntu 12.04 64bit. It takes about 35 minutes and 30G disk space on a intel 4770 processor(i7, quad core, 3.4Ghz) machine with 16G ram and SSD.
Initializing a Build Environment
- Refer instructions from Google. Below is what we tested and set up the environment.
Install JDK
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java6-installer
Install required packages
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
Note: on Ubuntu 13.10, the package ia32-libs is removed, just ignore it.
Install ARM toolchain and building kernel related pacakges
sudo apt-get install gcc-arm-linux-gnueabihf sudo apt-get install lzop libncurses5-dev export ARCH=arm export CROSS_COMPILE=arm-linux-gnueabihf-
Install libraries for other tools
sudo apt-get install libssl1.0.0 libssl-dev
Get the source code
wget http://dl.radxa.com/rock/source/radxa_rock_android.tar.gz #(mirror1: BaiduYun) tar zxf radxa_rock_android.tar.gz cd radxa_rock_android git checkout .
Or if you can access the private git server, you can clone with the following command:
git clone -b radxa-dev git@git.linux-rockchip.org:radxa/radxa_rock_android.git cd radxa_rock_android
Note: If someone pushed the repo to github, let me know(tom@radxa.com). I have some problems pushing it to github because of large files.
Build the kernel
export ARCH=arm cd kernel make rk3188_radxa_rock_defconfig make kernel.img #kernel.img is the normal kernel image with rockchip crc cd ..
Build android source code
source build/envsetup.sh lunch rk31sdk-eng make -j8
Generate the image
./mkimage.sh ota
you will get boot.img recovery.img system.img under rockdev/Image, and update.img under rockdev
Flash the image
Next, follow the rock/flash the image to flash the image you just build.
