2)OCI image generation.
    -OCI image generation is for broadband application developers, in which they will create their aplication irespective of platform. That image will be competable with all the plaforms but only difference is they need to define the arch of the platform like 32 bit and 64 bit or they can use this to develop applcation for 86 arch based also.
    - As mentioned we will be using generic code for the generation of OCI image , so that will be meta-dac-sdk-broadband meta layer .(https://github.com/rdkcentral/meta-dac-sdk-broadband)
    - As this is platform independent, but you can follow mentioned Jira for any query with respect to oci image image generation for BPIR4.

• Generate OCI bundle from the OCI image using Bundlegen tool
  
  • git clone https://github.com/rdkcentral/BundleGen.git  (clone Bundlegen code.)
  • cd BundleGen
  • export PYTHONPATH=/usr/lib/python3.8/site:$PYTHONPATH
  • tar -xvf dac-image-iperf3-raspberrypi4-20240930100642.rootfs-oci.tar
  • bundlegen generate --platform rpi4_reference_bb_kirkstone oci:dac-image-iperf3-raspberrypi4-20240930100642.rootfs-oci.tar ~/iperf332 (creates the iperf332.tar.gz bundle file)
