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

repo init -u https://github.com/rockchip-linux/manifests https://github.com/rockchip-linux/manifests -m rk3399.xml

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

Debian

You can download the prebuilt image directly.

Baidu Pan、Google Drive

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

Yocto

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

Buildroot

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