Introduction

This page is dedicated to bring up yocto 3.1 upgradation for RDK generic camera image.

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

$ 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

Build Procedure

$ repo init -u "https://code.rdkcentral.com/r/manifests" -m rdkc-nosrc.xml -b yocto-dunfell-upgrade
$ repo sync
$ source meta-cmf-raspberrypi/setup-environment (Choose 11 `meta-cmf-raspberrypi/conf/machine/raspberrypi0-rdk-camera.conf`)
$ bitbake rdk-generic-camera-image

Image Flash Procedure

$ bzcat ImageName.wic.bz2 | sudo dd of=/dev/sdc bs=4M iflag=fullblock oflag=direct conv=fsync

Ex:
bzcat rdk-generic-camera-image-raspberrypi0-rdk-camera.wic.bz2 | sudo dd of=/dev/sdc bs=4M iflag=fullblock oflag=direct conv=fsync

User Manual for Supported Feature

Known Issues and Limitations

1.  Ethernet connection ( USB Ethernet Adapter):
   •  Able to get 'Ethernet IP' but unable to ping any address like www.google.com due to this issue not able to validate RMS feature.
2.  WiFi connection:
   •  After bootup unable to get the 'WiFi IP' address by default.
   • Once we restart the " wpa_supplicant.service" forcefully then we can able to get the 'WiFi IP'.
3.  RDKC Media Streamer( RMS )
   • After bootup, RMS services are not running.
   • Everytime manually we need to run this  " rms-launcher.service" command to launch rms.
