• Dockerfile⁠

⁠Docker container start up

1. Install Docker in host machine:

   $ sudo apt install docker.io
   $ sudo groupadd docker
   $ sudo usermod -aG docker $USER
   $ sudo systemctl enable docker
   $ sudo systemctl start docker
   

   Copy

2. Download buildroot repository to host machine:

   $ cd ~/git
   $ git clone https://github.com/od-contrib/buildroot-rg350-old-kernel
   

   Copy

3. Run container:

   $ docker run -it -v ~/git:/root/git --name RG350_buster_buildroot eduardofilo/rg350_buster_buildroot
   

   Copy

⁠Container connection

Once created, we can connect with container with:

$ docker exec -it RG350_buster_buildroot /bin/bash

If previous command returns an error indicating that the container is stopped, we can start it before executing the command:

$ docker start RG350_buster_buildroot

⁠Working with RG350 Buildroot

Once we are in container terminal, these are the things that can be done:

• To config Buildroot (only necessary first time):

  # cd ~/git/buildroot-rg350-old-kernel
  # make rg350_defconfig BR2_EXTERNAL=board/opendingux
  

  Copy

• OPTIONAL. We can personalize Buildroot with one of this command (use one or the other):

  # cd ~/git/buildroot-rg350-old-kernel
  # make menuconfig
  # make nconfig
  

  Copy

• To build toolchain (only necessary first time):

  # cd ~/git/buildroot-rg350-old-kernel
  # export BR2_JLEVEL=0
  # make toolchain
  

  Copy

• To build particular libraries and packages, for example to build SDL and SDL_Image:

  # cd ~/git/buildroot-rg350-old-kernel
  # export BR2_JLEVEL=0
  # make sdl sdl_image
  

  Copy

• OPTIONAL. If you want to include a set of default applications, emulators, and games from various sources, run this command (you only need to do this once):

  # cd ~/git/buildroot-rg350-old-kernel
  # board/opendingux/gcw0/download_local_pack.sh
  

  Copy

• To build the OS image, run:

  # cd ~/git/buildroot-rg350-old-kernel
  # board/opendingux/gcw0/make_initial_image.sh rg350
  

  Copy

The image will saved to: ~/git/buildroot-rg350-old-kernel/output/images/od-imager/images/sd_image.bin

The entire compilation process generates about 12GB of files.
