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 $ sudo apt-get install git cmake autoconf texinfo openjdk-8-jdk openjdk-8-jre \ m4 libtool libtool-bin curl pkg-config lib32z1 doxygen
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/manifests -b dunfell -m rdkb-extsrc.xml $ repo sync -j`nproc` --no-clone-bundle
Please cherry-pick the below changes ,
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
