Host Setup

The OpenEmbedded build system should be able to run on Ubuntu 18.04 distribution/other compatible linux distribution with the following versions for Git, tar, and Python.

  • Git 1.8.3.1 or greater
  • tar 1.27 or greater
  • Python 3.4.0 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

Repo Setup

In order to use Yocto build system, the repo tool must be properly installed on the machine.

To install Repo make sure you have a /bin directory in your home directory and that it is included in your path

Repo Setup Steps
$ mkdir ~/bin
$ PATH=~/bin:$PATH
Download the repo tool and ensure that it is executable
$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Note: it is also recommended to put credentials in ~/.netrc when interacting with repo.

A sample ~/.netrc file is illustrated below

.netrc
machine code.rdkcentral.com login YOUR_USERNAME password YOUR_PASSWORD

Yocto Build Steps

To build, follow below instructions

Build Steps
$ mkdir <workspace dir>
$ cd <workspace dir>
$ repo init -u https://code.rdkcentral.com/r/reference/manifests -m rdkb-extsrc.xml -b dunfell
$ repo sync -j`nproc` --no-clone-bundle



pam crash on 64bit aarch 
$ cd ~/rdkb/components/opensource/ccsp/CcspPandM
git fetch https://code.rdkcentral.com/r/rdkb/components/opensource/ccsp/CcspPandM refs/changes/04/62804/1 && git cherry-pick FETCH_HEAD


Note : The above bug fixes changes are temporary given as instructions. This is not required once the change is gets merged into the appropriate repo.

Image Generation Steps
$ MACHINE=raspberrypi4-64-rdk-broadband source meta-cmf-raspberrypi/setup-environment
$ bitbake rdk-generic-broadband-image


Flashing Procedure

Following command can be used to flash the RPI image to sd card using linux machine . bmap tool should be available in linux

Flash command
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-generic-broadband-image-raspberrypi4-64-rdk-broadband.wic.bz2
$ sudo -E bmaptool copy --nobmap rdk-generic-broadband-image-raspberrypi4-64-rdk-broadband.wic /dev/sdb
