Build Setup Instructions

Setting up the Host Environment

  • The OpenEmbedded build system should be able to run on Ubuntu 20.0 distribution/other compatible linux distribution with the following versions for Git, tar, and Python.

    • Git 2.25.1 or greater
    • tar 1.30 or greater
    • Python 3.10.4 or greater
    • Coreutils(E.g realpath)

    Note: You should also have about 50 Gbytes of free disk space for building images.

    The essential packages you need for a supported Ubuntu or Debian distribution are shown in the following command:

    $ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
      build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \
      xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \
      pylint3 xterm bmap-tools
     
    $ sudo apt-get install git cmake autoconf texinfo openjdk-8-jdk openjdk-8-jre \
      m4 libtool libtool-bin curl pkg-config lib32z1 doxygen
    $ sudo apt-get install gcc-multilib g++-multilib

Configure Git

Upgrade your Git version to 1.8.x or higher

Flashing the RPI Image

  • The micro SD card should be formatted (FAT) before writing the RPI image to it.  The minimum SD card size that can be used is 2GB. 
  • Using dd on linux/macOS:
bzcat <IMAGE_NAME>.wic.bz2 | sudo dd of=/dev/sdb bs=4M iflag=fullblock oflag=direct conv=fsync
  • Using bmaptool:
bzip2 -d <path to ImageName.wic.bz2>
sudo -E bmaptool copy --nobmap <path to ImageName.wic> <path to SD card space>
  
Example:
$ bzip2 -d rdk-ipstb-oss-image_rdk-next_20241208053801.rootfs.wic.bz2
$ sudo -E bmaptool copy --nobmap rdk-ipstb-oss-image_rdk-next_20241208053801.rootfs.wic.bz2 /dev/sda
  • You can also use applications like BalenaEtcher to flash a micro SD card with the RPI image.
