How to connect ethernet port to PL

[rgbblue]

Hi, I want to send data via ethernet to my board - PYNQ Z1 - and then do some basic data processing on it. For example, the data I send could be information about a stock, and then I have verilog to unpack the data and do basic processing on it, then put together a message to output via ethernet again. How would I do this - in particular, is it at all possible?, if so, what IPs would I need and how would I wire them up to my “data_processing_unit”. I want to use the existing ethernet port on the board too if possible. If there are any tutorials or recommendations on this, that would also be greatly appreciated.

Hi @rgbblue,

The Ethernet port on the PYNQ-Z1 is connected to the PS.
If you would like to accelerate data on the PL, you will have to transfer to it.

I suggest you check the DMA tutorial for this.

Tutorial: PYNQ DMA (Part 1: Hardware design)

PYNQ DMA tutorial (Part 1: Hardware design) This tutorial will show you how to use the Xilinx AXI DMA with PYNQ. It will cover adding the AXI DMA to a new Vivado hardware design and show how the DMA can be controlled from PYNQ. This tutorial is based on the v2.6 PYNQ image and will use Vivado 2020.1. If you are using a different PYNQ version you should be able to follow the same steps in this tutorial, but you should make sure you are using the supported version of Vivado for that PYNQ release. …

Cool thank you, I don’t really want to use python libraries to access the DMA, to read from and write to it - for learning purposes, How would I go about this?

Hi @rgbblue,

If you’re not planning to use PYNQ, you may be better of checking in the Xilinx forums.
Check the Vitis embedded application development documentation to see how you can do this.
