Design Components

This module requires the following components:

zcu102_base_trd (Vitis platform)

Build Flow Tutorials

PetaLinux BSP

This tutorial shows how to build the Linux image and boot image using the PetaLinux build tool. This step assumes you have run through the PetaLinux project creation step in DM1 previously.

Select the device-tree matching design module 8 and build all Linux image components. If you have run petalinux-build in a previous module, the build step will be incremental.
Code Block
language bash
theme Midnight
% cd $TRD_HOME/petalinux/bsp/project-spec/meta-user/recipes-bsp/device-tree/files/ % cp zcu102-base-dm8.dtsi system-user.dtsi % petalinux-build

2D Filter Accelerator

This tutorial shows how to build the 2D filter accelerator with HW acceleration based on the Base TRD Vitis platform.

setup the environment by sourcing the vitis and xilinx runtime (XRT) tools.

Build the project using the make file.This can take several hours.

Code Block

language	bash
theme	Midnight

% cd $TRD_HOME/zcu102_base_trd/samples/filter2d_pl/
% make PLATFORM=$TRD_HOME/zcu102_base_trd/zcu102_base_trd.xpfm XFOPENCV_INCDIR=$TRD_HOME/zcu102_base_trd/sw/zcu102_base_trd/a53_linux/inc/xfopencv PPC=XF_NPPC1

make will create the accelerated filter2d platform and outputs the xclbin, and bitstream.

Generate BOOT.BIN from the obtained bitstream, copy xclibin and linux image to sd card once the build is finished.

Code Block

language	bash
theme	Midnight

% cp $TRD_HOME/zcu102_base_trd/samples/filter2d_pl/binary_container_1.xclbin  $TRD_HOME/sd_card/dm8
% cp $TRD_HOME/zcu102_base_trd/samples/filter2d_pl/_x/link/int/system.bit  $TRD_HOME/petalinux/bsp/images/linux 
% cd $TRD_HOME/petalinux/bsp/images/linux
% petalinux-package --boot --bif=../../project-spec/boot/dm6.bif --force 
% cp BOOT.BIN image.ub boot.scr  $TRD_HOME/sd_card/dm8

Run Flow Tutorial

See here for board setup instructions.
Copy all the files from the $TRD_HOME/sd_card/dm8 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). The application will detect whether DP Tx or HDMI Tx is connected and output on the corresponding display device.
To re-start the TRD application with the max supported resolution, run
Code Block
language bash
theme Midnight
% run_video.sh
To re-start the TRD application with a specific supported resolution use the -r switch e.g. for 1920x1080, run
Code Block
language bash
theme Midnight
% run_video.sh -r 1920x1080
The user can now control the application from the GUI's control bar (bottom) displayed on the monitor.
The user can select from the following video source options:
- TPG (SW): virtual video device that emulates a USB webcam purely in software
- USB: USB Webcam using the universal video class (UVC) driver
- TPG (PL): Test Pattern Generator implemented in the PL
- HDMI: HDMI input implemented in the PL
- CSI: MIPI CSI image sensor input implemented in the PL
- File: Raw video file source
The user can select from the following accelerator options:
- Passthrough (no accelerator)
- 2D convolution filter with configurable coefficients
The supported accelerator modes depend on the selected filter:
- SW - accelerator is run on A53
- HW - accelerator is run on 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.
