Updates in meta-xilinx:

  1. In 2017.x releases, we used to fork from upstream meta-xilinx release and remove all the unsupported boards (like microzed), SPL to create release branches.
    To prevent forking, from 2018.x releases, all patches for Xilinx release sit on top of upstream meta-xilinx release (Rocko v2.4).
    We use PREFERRED_PROVIDER switch to select the components: For example all the release testing is done with these PREFERRED_PROVIDERS

  2. SOC_FAMILY: This is a defined override variable from OE-core that groups together machines based upon the same family of SOC (System On Chip).
    This is defined as "zynqmp" for MPSoC devices, "zynq" for Zynq7000 devices in meta-xilinx layer. See

  3. {SOC_FAMILY}{SOC_VARIANT}: This is a new override based on the Xilinx product table and value of SOC_VARIANT can be "cg", "eg", "ev", "dr" for MPSoC devices and "7zs" or "7z" for Zynq 7000 devices. See

    By default, the Zynq devices are set to "7z" and
    By default, the MPSoC devices are set to "eg"

  4. mali400, vcu : This extends overrides from SOC_VARIANT, and is set to mali400 or vcu or both depending on the functionality of the set SOC_VARIANT device

  • Use Rocko meta-xilinx from upstream:
    • meta-xilinx is an umbrella which has meta-xilinx-bsp and meta-xilinx-contrib layers from Rocko v2.4

  • New machine support
    • Add support for zcu106 evaluation board
    • Add support for zcu104 evaluation board
    • Add support for zc1254 evaluation board
    • Add support for zc1275 evaluation board
    • Add support for zcu111 evaluation board

Updates in meta-xilinx-tools:

  • Xsct now can use the Xvfb and xlsclients from HOSTTOOLS instead of hardcoded /usr/bin path.
    • Xvfb and xlsclients is added as HOSTTOOLS, meaning this has to be installed in host system using 'apt-get install -y xvfb x11-utils'

  • Change xilinx-bootbin from a class to a bb recipe: This helps in easy overrides using bbappends and using PREFERRED_PROVIDER for bootbin generation
  • device-tree.bbappend: device-tree-generation recipe is removed and replaced with device-tree.bbappend. device-tree recipe is available in meta-xilinx layer, this just extends the recipe to use DTG.
    • add hooks for all new boards: zcu111, zcu106, zcu104, zc1254, zc1275

  • Add support for dsa : dsa is a new format from Vivado tools which will be introduced from 2018.3 release
