Zynq GEM Reference Designs for Ethernet FMC

Description

This project demonstrates the use of the Opsero Ethernet FMC (OP031) and Robust Ethernet FMC (OP041). The design uses the GMII-to-RGMII IP core to connect the hard GEMs of the Zynq PS to the Ethernet FMC PHYs. The designs target both the Zynq and ZynqMP devices and are illustrated by the block diagrams below.

Requirements

This project is designed for version 2024.1 of the Xilinx tools (Vivado/Vitis/PetaLinux). If you are using an older version of the Xilinx tools, then refer to the release tags to find the version of this repository that matches your version of the tools.

In order to test this design on hardware, you will need the following:

• Vivado 2024.1
• Vitis 2024.1
• PetaLinux Tools 2024.1
• Ethernet FMC or Robust Ethernet FMC
• One of the target platforms listed below
• For designs containing AXI Ethernet Subsystem IP: Xilinx Soft TEMAC license

Target designs

This repo contains several designs that target various supported development boards and their FMC connectors. The table below lists the target design name, the number of ports supported by the design and the FMC connector on which to connect the mezzanine card. Some of the target designs require a license to generate a bitstream with the AMD Xilinx tools.

Software

These reference designs can be driven by either a standalone application or within a PetaLinux environment. The repository includes all necessary scripts and code to build both environments. The table below outlines the corresponding applications available in each environment:

Environment	Available Applications
Standalone	lwIP Echo Server
PetaLinux	Built-in Linux commands Additional tools: ethtool, phytool, iperf3

Build instructions

Clone the repo:

git clone https://github.com/fpgadeveloper/ethernet-fmc-zynq-gem.git

Source Vivado and PetaLinux tools:

source <path-to-petalinux>/2024.1/settings.sh
source <path-to-vivado>/2024.1/settings64.sh

To build the standalone lwIP echo server application (Vivado project and Vitis workspace):

cd ethernet-fmc-zynq-gem/Vitis
make workspace TARGET=zcu106_hpc0

To build the PetaLinux image (Vivado project and PetaLinux):

cd ethernet-fmc-zynq-gem/PetaLinux
make petalinux TARGET=zcu106_hpc0

Replace the target label in these commands with the one corresponding to the target design of your choice from the tables above.
