Adding New RPM Packages in meta-petalinux

meta-petalinux supports various packages for Xilinx architectures.

However there might be a use-case when a user wants to add additional packages to create a rpm feed channel

Step-by-step guide

Add the steps involved:

1. meta-petalinux should be setup for Yocto build setup
   • Please refer to Getting Started With Yocto using Repo to build RPM Packages
2. For example we want to add wireless-tools package to Zynq/ZynqMP architecture
   • wireless-tools is a recipe present in Yocto project for supporting tools for Linux Standard Wireless Extension Subsystem
   • http://git.yoctoproject.org/cgit.cgi/poky/plain/meta/recipes-connectivity/wireless-tools/wireless-tools_30.pre9.bb
3. In meta-petalinux, packagegroup-petalinux.bb contains the information about all the packages being built for each architecture
   • https://github.com/Xilinx/meta-petalinux/blob/rel-v2016.1/recipes-core/packagegroups/packagegroup-petalinux.bb
   • Lets add the desired package at the end of ZYNQ_EXTRAS

• ZYNQ_EXTRAS = " \
      bonnie++ \
      hdparm \
      iperf \
      libattr \
      libinput \
      opencv \
      python-multiprocessing \
      python-numpy \
      python-scons \
      python-shell \
      python-threading \
      python-smartpm \
      smartmontools \
      v4l-utils \
      yavta \
      libmetal \
      wireless-tools \
      " 

• save the file
• bitbake to get the new RPM

• $ MACHINE=<architecture>-generic bitbake petalinux-image

• find -name "wireless-tools*rpm" in /tmp/deploy/rpm to verify it is built
