I am trying to run the lwIP echo server application project template from the Xilinx SDK on my PYNQ board. I have followed this tutorial for the. contrib/ports/xilinx – Contains the interface specific implementation || lwip 2 – Contains the stack implementation; lwip_echo_server is an application. Lightweight IP (lwIP) is an open source TCP/IP networking stack for Xilinx® Software Development Kit (SDK) provides lwIP software.

If you followed the first part of the tutorial correctly, you should not need to complete this step. Please verify the initialization sequence link speed for phy address 1: Now that the application is running successfully, we can test the echo server by sending packets from our PC to the ZedBoard and looking at what gets sent back.
At this point, your SDK workspace should contain only the hardware description and no applications:.
Solved: Cannot connect to lwIP echo server on Zynq – Community Forums
The reply suggests changing auto negotiation to fixed speed in the bsp, but I can’t seem to find an option to do this? Ah I did not know that there was a problem with the Realtek chips. Is there a specific reason for choosing only one ethernet MAC, deos lwIP support multiport application? They keep selling the zybo with ethernet with Realtek chips, probably because of price, but it is really not supported in any sense either by them or by Xilinx.
Once the software is installed, follow the instructions below to send and receive packets:. I would imagine that for a development board you’d get something whose components are solid it is and supported it is not by all the tools involved. I strongly recommend that you perform lwi; modifications to the sources in the Vivado installation files — lsip the sources in the BSP of your SDK workspace.
Embedded Processor System Design: It appears that in xlinx. Once I removed this, I ran the application and I am now able to connect: Have you tried 2 lwip echo server project in dual core. But then I looked at myself and asked – “am I an engineer or a soy boy? You see that the chip is not any of the ones supported Marvell or TI. Lwwip seems that the standard is so old that everyone has already converged. In the SDK we will be able to generate the echo server example design and run it on our hardware.
Then I had the hunch and everything xlinx. I have just tried turning on some of the debug options in the bsp and I am getting repeated warnings.

The software that I use is called Packet Sender and can be downloaded here. Please upgrade to a Xilinx.
If so, this was already enabled when I created the application project from the template:. However this thread indicates that it may be. We want to add some code to the application to allow us to select a different port if we choose. It never really worked, even following the tutorial – which is a monster cover up, mind you.
To test that the echo server is actually doing its job and echoing xilknx packets, you will have to install software that allows you to send and receive arbitrary packets. The BSP for this project will also have to be modified slightly.

Running a lwIP Echo Server on a Multi-port Ethernet design
Soumya on September 19, at 4: Follow these instructions to ensure that your setup is correct:. Notify me of follow-up comments by email. Notify me of new posts by email. If you want to experiment, you can play around with the software by sending more packets, or different kinds of packets. This seems to be confirmed by the DHCP timeout in the serial output.
I was going to sell it on ebay and buy a zedboard.
The PYNQ is telling my via serial comms that. Your email address will not be published. I really appreciate it. But then I hit this snag with the ethernet.
