Build AOSP for ROCK960

Build environment setup

Recommend build host is Ubuntu 16.04 64bit, for other hosts, refer official Android documents Establishing a Build Environment.

$ mkdir -p ~/bin
$ wget '' -P ~/bin
$ chmod +x ~/bin/repo

Android’s source code primarily consists of Java, C++, and XML files. To compile the source code, you’ll need to install OpenJDK 8, GNU C and C++ compilers, XML parsing libraries, ImageMagick, and several other related packages.

$ sudo apt-get update
$ sudo apt-get install openjdk-8-jdk android-tools-adb bc bison build-essential curl flex g++-multilib gcc-multilib gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc yasm zip zlib1g-dev

Configure the JAVA environment

$ export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
$ export PATH=$JAVA_HOME/bin:$PATH
$ export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

Download source code

$ mkdir rock960-android
$ cd rock960-android

Then run:

$ ~/bin/repo init -u -b rock960-box-7.1 -m rock960_box_7.1_release.xml
$ repo sync -j$(nproc) -c

It might take quite a bit of time to fetch the entire AOSP source code(around 86G)!

Build u-boot

$ cd u-boot
$ make rk3399_box_defconfig
$ ./
$ cd ..

The generated images are rk3399_loader_v_xxx.bin and uboot.img and idbloader.img

Building kernel

$ cd kernel
$ make rockchip_defconfig
# rock960 mode ab
$ make rk3399-rock960-model-ab.img -j$(nproc)
# rock960 mode c
$ make rk3399-rock960-model-c.img -j$(nproc)
$ cd ..

The generated images are kernel.img and resource.img:

  • kernel.img, kernel with rkcrc checksum
  • resource.img, contains dtb and boot logo, Rockchip format resource package

Building AOSP

$ source build/
$ lunch rk3399_box-userdebug
$ make -j$(nproc)

It takes a long time, take a break and wait…

Package images

$ ln -s RKTools/linux/Linux_Pack_Firmware/rockdev/ rockdev
$ ./

The generated images under rockdev/Image-rk3399_box are

boot.img    MiniLoaderAll.bin  parameter.txt        pcba_whole_misc.img  resource.img  trust.img
kernel.img  misc.img           pcba_small_misc.img  recovery.img         system.img    uboot.img

They can be flashed with fastboot or Rockchip upgrade_tool.
