Bundle Creation

• https://github.com/rdkcentral/BundleGen
  
  • New template for 64 bit kirkstone
    rpi4_64_reference_bb_kirkstone.jsonrpi4_64_reference_bb_kirkstone_libs.json
  • Generate OCI bundle from the OCI image using Bundlegen tool
    
    • Copy the oci image (dac-image-iperf3-raspberrypi4-20240930100642.rootfs-oci.tar) from build (path - /workspace/sep17--2/build/tmp/deploy/images/raspberrypi4)  to local VM where BundleGen is installed.
    • 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)
    • follow this  iperf3 application document to test the iperf3 application using dac
