BSP Linux on Orange Pi 4

BSP Linux used on an Orange Pi 4

(!) Xunlong's provided Linux is an older 4.4 series kernel.

Installing Pre-Built Images

(!) Pre-Built kernel doesn't have support for CIFS (Samba file sharing)

1. Download compressed *.img files from the vendor's page
2. Extract the image files
3. Flash the image to an SD Card

Building Custom Images

(!) Supplied build scripts use Rockchip's closed source binary toolkit rkbin/tools. This makes it unusable for running on the Orange Pi 4 (or any ARM device). The repository is usable only as a learning material.

[i] The build tool is designed to be executed on Ubuntu (preferably 18.04 Bionic) on a x86_64 machine.

Best option is to use vagrant and run the build OS virtually. If you by any chance run Ubuntu, feel free to ignore the vagrant-related instructions and run the other commands directly on your machine.

The build tool is using these repositories:

• OrangePiRK3399_kernel
• OrangePiRK3399_uboot
• OrangePiRK3399_scripts
• OrangePiRK3399_external
• toolchain

Vagrant setup

vagrant init hashicorp/bionic64
vagrant up
vagrant ssh
# inside vagrant:
  sudo apt-get update
  # additional packages not installed by the build tool
  sudo apt-get install liblz4-tool
  exit

Build Tools

vagrant ssh
# inside vagrant:
  git clone https://github.com/orangepi-xunlong/OrangePi_Build.git
  cd OrangePi_Build
  ./Build_OrangePi.sh
  exit

Enter your (sudo) password (empty when running under vagrant), let it download the repositories (listed above).

Building

vagrant ssh
# inside vagrant:
  cd OrangePiRK3399
  ./build.sh
  exit

Select '0 Orange Pi 4', '0 Build Release Image' and wait for the image to be built. TODO: I didn't actually try this, I just built the kernel.

Flashing

The same process applies as for the Pre-Built Images, see Flashing Linux to SD Card.
