Downloading Source Code & building

Downloading Source Code

Following commands fetch the source code using repo tool

$ mkdir <Directory-Name> && cd <Directory-Name>

Please use the following repo init command

repo init -u https://code.rdkcentral.com/r/rdkcmf/manifests -b kirkstone -m rdkv-nosrc.xml

repo sync -j `nproc` --no-clone-bundle --no-tags


Building

MACHINE=raspberrypi4-64-rdk-android-ipstb-oss source meta-cmf-raspberrypi/setup-environment

bitbake lib32-rdk-ipstb-oss-image

The above step configures and sets up your directory to start an appropriate build.  And bitbake  <image-name> is used to initiate the build 

On Successful build, the ROOTFS (in vmdk format) would be available at the following reference location based on the build type :

build-raspberrypi4-64-rdk-android-ipstb-oss/tmp/deploy/images/raspberrypi4-64-rdk-android-ipstb-oss/imagename.wic.bz2

Flashing the RPI Image

The micro SD card should be formatted (FAT) before writing the RPI image to it.  The minimum SD card size that can be used is 2GB. 

Using dd on linux/macOS:

bzcat <IMAGE_NAME>.wic.bz2 | sudo dd of=/dev/sdb bs=4M iflag=fullblock oflag=direct conv=fsync

Using bmaptool:

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-ipstb-oss-image_rdk-next_20241208053801.rootfs.wic.bz2
$ sudo -E bmaptool copy --nobmap rdk-ipstb-oss-image_rdk-next_20241208053801.rootfs.wic.bz2 /dev/sda

You can also use applications like BalenaEtcher to flash a micro SD card with the RPI image.
