Packet Switching Tutorial - Packet Switching Tutorial - 2025.2 English - XD100

Version: Vitis 2025.2

This tutorial targets AIE-ML device, but shares test cases and description files with AIE 04-packet-switching.

IMPORTANT: Before beginning the tutorial, install the AMD Vitis™ unified software platform 2025.2. This Vitis release includes all the embedded base platforms including the VCK190 base platform that this tutorial uses. Also, download the Common Images for Embedded Vitis Platforms from this link.

The ‘common image’ package contains a prebuilt Linux kernel and root file system that you can use with AMD Versal™ boards for embedded design development using Vitis tools.

Before starting this tutorial, run the following steps:

1. Go to the directory where you have unzipped the Versal Common Image package.

2. In a Bash shell, run the /**Common Images Dir**/xilinx-versal-common-v2025.2/environment-setup-cortexa72-cortexa53-amd-linux script. This script sets up the SDKTARGETSYSROOT and CXX variables. If the script is not present, you must run the /**Common Images Dir**/xilinx-versal-common-v2025.2/sdk.sh.

3. Set up your ROOTFS and IMAGE to point to the rootfs.ext4 and Image files located in the /**Common Images Dir**/xilinx-versal-common-v2025.2 directory.

4. Set up your PLATFORM_REPO_PATHS environment variable to $XILINX_VITIS/base_platforms.

This tutorial targets VEK280 board for 2025.2 version.
