Build Flow Tutorials

PL Base TRD

This tutorial shows how to build the Base TRD Vivado design that implements the TPG capture pipeline.

• Create a Vivado project. Select 'es1' instead if you are targeting a rev D board with ES1 silicon.

  % cd $TRD_HOME/pl/zcu102_base_trd % vivado -s ./scripts/create_project.tcl -tclargs -platform zcu102 -silicon es2

  
  

• Implement the design and generate a bitstream
  

• Copy the generated bitstream to the PetaLinux directory or alternatively use the pre-built bit file that is already bundled with the PetaLinux BSP.

  % cp -f project/zcu102_base_trd.runs/impl_1/zcu102_base_trd_wrapper.bit $TRD_HOME/apu/petalinux_bsp/images/linux

  
  

PMU Firmware

Please refer to design module 1 - PMU firmware for instructions or skip this step if you have built the PMU firmware in a previous module.

PetaLinux BSP

This tutorial shows how to build the Linux image and boot image using the PetaLinux build tool.

• The petalinux-config step can be skipped if this was already done in a previous module.

  % cd $TRD_HOME/apu/petalinux_bsp % petalinux-config --get-hw-description=./hw-description --oldconfig

  
  

• Select the device-tree matching design module 6 and build all Linux image components. If you have run petalinux-build in a previous module, the build step will be incremental.

  % cd subsystems/linux/configs/device-tree % cp system-dm6.dts system-top.dts % petalinux-build % cd -

  
  

• Create a boot image.

  % cd images/linux % petalinux-package --boot --bif=dm6.bif --force

  
  

• Copy the generated boot image and Linux image to the dm6 SD card directory.

  % mkdir -p $TRD_HOME/images/dm6/bin % cp autostart.sh BOOT.BIN image.ub $TRD_HOME/images/dm6

  
  

Video Qt Application

There is no need to rebuild the video_qt2 application if you have already built it in module 5, otherwise follow the instructions from module 5.

• Copy the generated video_qt2 executable to the dm6 SD card directory.

  % cp -f video_qt2/video_qt2 video_qt2/run_video.sh video_qt2/video_qt2_wrap.sh $TRD_HOME/images/dm6/bin

Run Flow Tutorial

• See here for board setup instructions.
• Copy all the files from the $TRD_HOME/images/dm6 SD card directory to a FAT formatted SD card.
• Power on the board to boot the images; make sure INIT_B, done and all power rail LEDs are lit green.
• After ~30 seconds, the display will turn on and the application will start automatically, targeting the max supported resolution of the monitor (one of 3840x2160 or 1920x1080 or 1280x720).

• Upon application exit, use the below login and password to log into the framebuffer or serial console:

  root@Xilinx-ZCU102-2016_3 login: root password: root

  
  

• The SD card file system is mounted at /media/card
• To re-start the TRD application type run_video.sh
• The user can now control the application from the GUI's control bar (bottom) displayed on the monitor.
  
• By default, application launches with VIVID as a video-source, user can also select TPG from the "Video-source selection" button present on the GUI's control-bar.
  • Virtual Video Device (VIVID): emulates a USB webcam purely in software
  • USB Webcam (UVC): using the universal video class driver
  • Test Pattern Generator (TPG); implemented in the PL
• The video info panel (top left) shows essential settings/statistics.
• The CPU utilization graph (top right) shows CPU load for each of the four A53 cores.
