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 git clone from the bitbucket repo:

   git clone -b radxa-dev https://bitbucket.org/radxa/android_radxa_rock.git

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.
