RK3399

Overview

RK3399 is a low power, high performance processor for computing, personal mobile internet devices and other smart device applications. Based on Big.Little architecture, it integrates dual-core Cortex-A72 and quad-core Cortex-A53 with separate NEON coprocessor.
Many embedded powerful hardware engines provide optimized performance for high-end application. RK3399 supports multi-format video decoders including H.264/H.265/VP9 up to4Kx2K@60fps, especially, H.264/H.265 decoders support 10bits coding, and also supports H.264/MVC/VP8 encoders by 1080p@30fps, high-quality JPEG encoder/decoder, and special image preprocessor and postprocessor.
Embedded 3D GPU makes RK3399 completely compatible with OpenGL ES1.1/2.0/3.0/3.1, OpenCL and DirectX 11.1. Special 2D hardware engine with MMU will maximize display performance and provide very smooth operation.
RK3399 has high-performance dual channel external memory interface (DDR3/DDR3L/LPDDR3/LPDDR4) capable of sustaining demanding memory bandwidths, also provides a complete set of peripheral interface to support very flexible applications.

How to get the sources

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

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.
