Host Setup

The OpenEmbedded build system should be able to run on any modern distribution with the following versions for Git, tar, and Python.

• Git 1.7.8 or greater.

• tar 1.24 or greater.

• Python 2.7.3 or greater excluding Python 3.x, which is not supported.

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

Ubuntu and Debian

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

sudo apt-get install make gcc g++ diffstat texinfo chrpath gcc-multilib git gawk build-essential autoconf libtool libncurses-dev gettext gperf lib32z1 libc6-i386 g++-multilib python-git

Building

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

Repo setup

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

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

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>

Follow below instructions to create build with external sources

$ repo init -u https://code.rdkcentral.com/r/manifests -b rdk-next -m rdkb-turris-pod-nosrcextsrc.xml -b rdk-next

$ repo sync -j4 --no-clone-bundle
MACHINE=turris-extender$ source meta-cmf-turrisraspberrypi/setup-environment build-turris-ext
 (Select option raspberrypi-rdk-broadband.conf)
$ bitbake rdk-generic-extenderbroadband-image

...

Note  :  On Successful build,The kernel Image and root filesystem will be created under the below path,

             ~/tmp/deploy/images/raspberrypi-rdk-broadband folder

Flashing Procedure

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

repo init -u https://code.rdkcentral.com/r/manifests -m rdkb-turris-pod-extsrc.xml -b rdk-next
repo sync -j4 --no-clone-bundle
MACHINE=turris-extender source meta-turris/setup-environment build-turris-ext
bitbake rdk-generic-extender-image

...

sudo dd if=<path to ImageName.rpi-sdimg> of=<path to SD card space> bs=4M
Example:
$ sudo dd if=rdk-generic-broadband-image-raspberrypi-rdk-broadband.rpi-sdimg of=/dev/sdb bs=4M
