Kria™ KV260 Vision AI Starter Kit Tutorial

Integrating the overlay into the Platform

Integrating the overlay into the Platform¶

Introduction:¶

This document provides the steps to integrate the overlay consisting of accelerated functions into the platform.

Prerequisites:¶

Vitis Unified Software Platform 2021.1

Accessing the Tutorial Reference Files¶

Note: Skip the following steps if the design files have already been cloned and extracted to a working repository

To access the reference files, type the following into a terminal:

git clone --branch release-2021.1 --recursive https://github.com/Xilinx/kria-vitis-platforms.git

Navigate to the kv260-vitis which is the working directory.

Integrating an overlay (accelerator functions) into a Vitis Extensible platform¶

Go to the working directory
```
cd $working_dir/
```
To compile and integrate the overlay into the platform, run the following command. The Makefile calls a lower level Makefile to run Vitis. If a platform is not already available it builds that as well.
```
make overlay OVERLAY=<application_name>
```
Applications currently supported are listed below

Application name	Platform used
smartcam	kv260_ispMipiRx_vcu_DP
aibox-reid	kv260_vcuDecode_vmixDP
defect-detect	kv260_ispMipiRx_vmixDP
nlp-smartvision	kv260_ispMipiRx_DP

The generated bitfile and xclbin will be located at
```
$working_dir/overlays/examples/<application_name>/binary_container_1/link/int/system.bit   
$working_dir/overlays/examples/<application_name>/binary_container_1/*.xclbin
```
The xclbin and bitfile generation may take couple of hours depending on the system specification. They will be used to build the Petaliunx image

Next Step¶

Building a Petalinux Image
Go back to the KV260 SOM designs start page
