Yocto Build Setup

All RPi based RDK images with the latest features are from the rdk-next branch

Initializing the Build Environment

To build RDK images from rdk-next branch, follow the below build procedure

mkdir workspace; cd workspace
# initialize the manifest with repo tool
repo init -u -b master -m rpi/release/rdkv-dunfell-21m2.xml
repo sync -j `nproc` --no-clone-bundle --no-tags

# revert cryptography related changes in wpeframework-clientlibraries (causing build error)
(cd meta-rdk-video; git revert 5cfd49b6e1a56540c1bbf9caada22cdb9097e0e2 --no-edit)

mkdir workspace; cd workspace
# initialize the manifest with repo tool
repo init -u -b master -m rpi/release/rdkv-morty-21m2.xml
repo sync -j `nproc` --no-clone-bundle --no-tags

Image Build

MACHINE=raspberrypi-rdk-mc source meta-cmf-raspberrypi/setup-environment

bitbake rdk-generic-mediaclient-wpe-image

MACHINE=raspberrypi-rdk-hybrid source meta-cmf-raspberrypi/setup-environment

bitbake rdk-generic-hybrid-wpe-image

MACHINE=raspberrypirdkhybrefapp source meta-cmf-raspberrypi/setup-environment

bitbake rdk-generic-hybrid-refapp-image

The Kernel image and root file-system collectively created as an image and it will be available under build-<MACHINE>/tmp/deploy/images/<MACHINE> folder.

Flash Procedure

# of - output file (the device file for the inserted micro SD card
bzcat <IMAGE_NAME>-<MACHINE>.wic.bz2 | sudo dd of=/dev/<sd_file> bs=4M iflag=fullblock oflag=direct conv=fsync
# eg. bzcat rdk-generic-mediaclient-wpe-image-raspberrypi-rdk-mc.wic.bz2 | sudo dd of=/dev/sdc bs=4M iflag=fullblock oflag=direct conv=fsync

# Insert the micro SD card and mention the card's device file name
# input file (if) is the image file to flash and the output file (of) is the card's device file name
sudo dd if=<IMAGE_NAME>-<MACHINE>.rpi-sdimg of=/dev/<sd_file> bs=4M
# Eg. sudo dd if=rdk-generic-mediaclient-wpe-image-raspberrypi-rdk-mc.rpi-sdimg of=/dev/sdc bs=4M
