Git- 1.8.3.1 or greater Python- 3.8.10 tar- 1.24 or greater
The instructions provided below are meant to be executed via the command line on an Ubuntu machine.
# essential packages installation # super user mode is required # major essential packages sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib g++-multilib build-essential chrpath socat bison curl cpio python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint3 xterm
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”.
Upgrade your Git version to 1.8.x or higher.
Once git is installed, configure your name and email using the below commands.
# review your existing configuration git config --list --show-origin # configure user name and email address git config --global user.name "John Doe" git config --global user.email johndoe@example.com # configure git cookies. Needed for Gerrit to only contact the LDAP backend once. git config --global http.cookieFile /tmp/gitcookie.txt git config --global http.saveCookies true
In order to use Yocto build system, first you need to make sure that repo is properly installed on the machine:
# create a bin directory mkdir ~/bin export 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 the repo.
A sample .netrc file is illustrated below.
machine code.rdkcentral.com login <YOUR_USERNAME> password <YOUR_PASSWORD> |
---|
# initialize the manifest with repo tool repo init -u https://code.rdkcentral.com/r/manifests -b 6.0.0 -m rdkv.xml repo sync --no-clone-bundle --no-tags MACHINE=raspberrypi4-64-rdk-android-mc source meta-cmf-raspberrypi/setup-environment bitbake lib32-rdk-generic-mediaclient-wpe-image # To build tdk image bitbake lib32-rdk-generic-mediaclient-wpe-tdk-image
The generated image resides under the directory build-<MACHINE>/tmp/deploy/images/<MACHINE>
of the Yocto workspace.
This section outlines two methods for flashing: Flashing the SD Card (flashing steps in a Linux environment) and using balenaEtcher App (flashing in windows).
1. Insert an SD card in the SD card port of the USB SD card reader (or Laptop).
(Prefer to use 32gb sd card and there should be minimum 12gb free space available in the device.)
2. Verify that the SD card has been detected by executing either of the commands listed below.

To flash the image on an SD card, you will need to download the balenaEtcher application-https://www.balena.io/etcher/ .
*Note: Prefer to use a 32GB sd card and there should be a minimum of 12GB of free space available in the device. Be sure to remove all other portable flash drives/hard drives/SD cards from your computer before flashing the RDK image.
Once image flashing is done, remove the SD card from the device/laptop and insert the SD card into the microSD card slot on the underside of your Raspberry Pi.
Power on the RaspberryPi.
