RK3328 consists of Quad-core A53 application processor .

Quad-core Cortex-A53 is integrated with separate Neon and FPU coprocessor, also with shared L2 Cache. 

Lots of high-performance interface to get very flexible solution, such as multi-channel display with HDMI2.0a, TV Encoder. TrustZone and crypto hardware are integrated for security. 32bits DDR3/DDR3L/DDR4/LPDDR3 provides high memory bandwidths.

The rockchip linux SDK source tree is located in multi Git repository hosted by Github. The SDK uses repo to sync down source code. Beside the generic community Linux support, we have chip optimized Linux SDK and it's also opensource and can get source from github.

RK3399 optimized Debian & Buildroot

repo init -u https://github.com/rockchip-linux/manifests https://github.com/rockchip-linux/manifests -m rk3399.xml repo sync How to build the sources

Build Environment

You need a 64-bit Ubuntu. Note: old versions Ubuntu maybe have compatibility issues. Use below commands to install Ubuntu packages: $ sudo apt-get install git gnupg flex bison gperf build-essential \ zip tar curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \ libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \ libgl1-mesa-dev g++-multilib mingw32 cmake tofrodos \ python-markdown libxml2-utils xsltproc zlib1g-dev:i386 lzop $ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gn u/libGL.so

Install ARM cross-compile tool chain and compile kernel relative software package: 

$ sudo apt-get install gcc-arm-linux-gnueabihf gcc-aarch64-linux-gnu device-tree-compiler lzop libncurses5-dev libssl1.0.0 libssl-dev

Installing the build tools and download source

Please follow linux user guide to install the build tools and download source.

Building kernel

For ARM V8 (RK3399 optimized SDK)

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- rockchip_linux_defconfig make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- rk3399-sapphire-excavator-linux.img -j4 Building uboot

For RK3399 optimized SDK (rkproduct uboot)

CROSS_COMPILE=aarch64-linux-gnu- make rk3399_linux_defconfig all Building rootfs


Yu can download the prebuilt image directly.

Baidu Pan、Google Drive

or you could use the rootfs-build-script from Rockchip to build rootfs yourselves.


If you want to use Yocto to build your rootfs see yocto-user-guide for detail.


If you want to use Buildroot to build your rootfs see buildroot-user-guide for detail.


If you need the rk3399-excavator board, please communicate through the following contact information.
