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.

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

$ 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

$ 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
$ 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

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

OEM Side Changes Required

Global CFLAGS

NOTE: This can be added in ccsp_common inc files. So, will be available for all ccsp components.

CFLAGS_append_aarch64 = " -D_64BIT_ARCH_SUPPORT_ "

For DBUS Enabling support

            By default, rbus is enabled in rpi4 64b build. For dbus enabling in rpi4 64b build, please follow the below steps,

Delete the below lines from below file's,
 
File path : ~/meta-cmf-raspberrypi/meta-rdk-broadband/recipes-ccsp/util/utopia.bbappend
    touch \/nvram\/rbus_support ' ${D}${sysconfdir}/utopia/utopia_init.sh 

File path : ~/meta-cmf-raspberrypi/recipes-core/dbus/dbus_%.bbappend

{ 
# Removing dbus service in 64bit arch alone
 rm ${D}${systemd_system_unitdir}/dbus.service
