A VCU-based design example is now available for the UltraZED-EV SOM and Carrier Card.

 

The VCU implementation was ported from the Xilinx v2018.3 ZCU106 VCU TRD design, so this example is setup (architecturally) to be extended to incorporate the other TRD design module capabilities.

 

If you just want to dive in, jump straight to the release and test notes in the repository:

    • A Petalinux v2018.3 BSP
    • Pre-built SD-Card images (for booting from microSD)
    • Instructions for testing the design on the UZ7EV SOM with Carrier Card
    • Documentation of the porting process used to generate this design
  • Testing the Design:Design Testing on the UltraZED-EV + Carrier Card
    The Test Notes contain instructions for configuring and using the major design features under Linux from the Gstreamer Framework, including:
    • Configuring and Working with the DisplayPort Interface
    • Testing the VCU Decoder with local playback
    • Configuring and Working with a USB Webcam with local preview
    • Testing the VCU Encoder with local playback and network streaming (RTP/UDP)

 

Design information:

Base v2018.3 Vivado+Petalinux Design with:

  • LEDs, DIP Switches, Pushbuttons
  • DisplayPort, USB Host/Device Support, Console UART
  • VCU Support (H.264, H.265, Encoder/Decoder)
  • GStreamer / V4L2 framework and tools
