Debian System Compilation

Hardware Configuration

Recommended hardware configuration for compiling Ubuntu development environment:

  • 64-bit CPU

  • Ubuntu 20.04, do not use Windows Subsystem (WSL)

  • 16GB of RAM

  • 250GB free space for compiling

  • Normal user to compile, do not use root user to compile

Software Configuration

Install environment packages

sudo apt update
sudo apt-get install git ssh make gcc libssl-dev liblz4-tool \
expect g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support \
qemu-user-static live-build bison flex fakeroot cmake gcc-multilib g++-multilib \
unzip device-tree-compiler libncurses-dev

sudo pip install python-pip pyelftools

Get SDK

Email support@neardi.com for development materials

After downloading, check the MD5 code and Neardi-3588-SDK-Linux-${Version}.tar.gz.md5sum for consistency before unzipping:

$ md5sum Neardi-3588-SDK-Linux-${Version}.tar.gz
******************************** Neardi-3588-SDK-Linux-${Version}.tar.gz

Unzip:

tar zxvf Neardi-3588-SDK-Linux-${Version}.tar.gz

Extract:

cd Neardi-3588-SDK-Linux-${Version}
git reset --hard

Switch branches:

branch explain
LZ16000002 Neardi master branch
git checkout LZ16000002

Compile SDK

Select Configuration

boardConfig explain
BoardConfig-rk3588-neardi-linux-lpb3588-f0.mk HDMIIN + HDMI1 + HDMI2 + HDMI3 + DP
./build.sh lunch BoardConfig-rk3588-neardi-linux-lpb3588-f0.mk

Fully Automatic Compilation

For the first compilation of the SDK, it is imperative to compile everything once, otherwise packaging will fail.

Fully automatic compilation will execute all compilations, generating u-boot, kernel, and buildroot.

./build.sh

Partial Compilation

  • Compile u-boot

./build.sh uboot
  • Compile kernel

./build.sh kernel
  • Compile recovery

./build.sh recovery

Compile Debian

./build.sh debian

Packaging Firmware

RK firmware is packaged in a proprietary format by Rockchip, and can be flashed onto eMMC or SD card using tools provided by Rockchip (Note: Unless specified otherwise, the firmware mentioned on the WIKI by default refers to RK firmware).

# Package RK firmware
./build.sh updateimg

The complete firmware will be saved to  rockdev/update.img
