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 'https://storage.googleapis.com/git-repo-downloads/repo' -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 python git-core gnupg flex bison gperf build-essential \
zip curl liblz4-tool zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \

htop iotop sysstat iftop pigz bc device-tree-compiler lunzip \

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-android9
$ cd rock960-android9
Then run:
$ ~/bin/repo init -u https://github.com/96rocks/manifests.git -b rock960-box-9.0 -m rock960_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.sh rk3399
$ cd ..
The generated images are rk3399_loader_v_xxx.bin and uboot.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/envsetup.sh
# Tv Box
$ lunch rk3399_box-userdebug
# Tablet
$ lunch rk3399-userdebug
$ make -j$(nproc)
It takes a long time, take a break and wait…
Package images
