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
   Note if the sdk is android5.x you should install java 7 as below
   sudo apt-get install openjdk-7-jdk

Install required packages - ubuntu 12.04

   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

Install required packages - ubuntu 13.10 and 14.04

   sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev\
   libesd0-dev libwxgtk2.8-dev squashfs-tools build-essential zip curl\
   libncurses5-dev zlib1g-dev pngcrush schedtool libxml2 libxml2-utils\
   xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev\
   lib32readline-gplv2-dev gcc-multilib libswitch-perl

Install ARM toolchain and building kernel related pacakges

   sudo apt-get install lzop libncurses5-dev

Install libraries for other tools

   sudo apt-get install libssl1.0.0 libssl-dev

Get the source code

Git clone from the linux-rockchip mirror servers. ( is located at U.S.A.)

For android 4.2.2 Jelly Bean (rock)

   git clone -b radxa/radxa-dev

For android 4.2.2 Jelly Bean (rock pro)

   git clone -b radxa/radxa-dev-rock_pro

For android 4.4.2 KitKat (rock pro & rock lite)

   git clone -b radxa/rock2014


   Download from Mega radxa_rock_android4-4_141219.tar.gz

Note: After unzip the file please run git checkout . to get the code

Build the kernel

   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 ..

note: if you want to build android sdcard image for rock pro, you need to run make menuconfig and go to Device Drivers ---> MMC/SD/SDIO card support, and disable RK29 SDMMC0 controller support(sdmmc), for rock lite the sdmmc0 driver is already disabled in defconfig.

Build android source code

   source build/
   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

Generate the image

   ./ ota

you will get boot.img recovery.img system.img under rockdev/Image, and update.img under rockdev

generate the image for sdcard(optional)

   cd rockdev && ./

android_xx-xx-x_sdcard.img is the generated image for sd card.

Note: How to write the image on sdcard, you can refer to , You can't use

Flash the image

Next, follow the flash to NAND flash to flash the image to NADN flash you just build. Or follow flash to sd card to write the image on sd card.
