Yocto Build Steps

To build, follow below instructions

Build Steps

Install the following packages for setting up your host VM

The instructions provided below are meant to be executed via the command line on an Ubuntu machine:

$ mkdir <workspace dir>
$ cd <workspace dir>
$ repo  sudoinit apt-get   install     build-essential gettext bison libfile-slurp-perl gawk libncurses-dev autoconf flex doxygen libtool automake   libpcre3-dev zlib1g-dev libbz2-dev subversion minicom putty libssl-dev rpm python-pexpect python-svn python-argparse vim tofrodos meld dos2unix cmake uuid-dev ruby transfig libglib2.0-dev xutils-dev lynx-cur gperf autopoint   python-dulwich   python-dev curl vim diffstat texinfo chrpath   openjdk-7-jre

Note : Please note openjdk-7-jre package is not available for Ubuntu-16.04 anymore. Presumably openjdk-8-jre should be used instead.

Configure bash as default command interpreter for shell scripts

sudo dpkg-reconfigure dash

Select “No”
To choose bash, when the prompt asks if you want to use dash as the default system shell - select “No”

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
Repo Setup Steps

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

A sample .netrc file is illustrated below

...

u https://code.rdkcentral.com/r/manifests -b rdk-next -m rdkb-extsrc.xml
$ repo sync -j4 --no-clone-bundle
$ source meta-cmf-raspberrypi/setup-environment (Select option raspberrypi-rdk-broadband.conf)
$ bitbake rdk-generic-broadband-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

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
