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.

Here is my full serial output: Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Then I had xolinx hunch and everything worked. The next page allows you to create the new application based on a template. I would imagine that for a development xllinx you’d get something whose components are solid it is and supported it is not by all the tools involved.

In this part of the tutorial we will generate the bitstream, export the hardware description to the SDK and then test the echo server application on our hardware.

At this point, your SDK workspace should contain only the hardware description and no applications:. Zynq GEM, Ethernet lite, etc.

I have a zybo board and it has a Realtek chip. But i see that you have solved it.

I really appreciate it. Your email address will not be published. Once the bitstream is generated, the following window will appear. Noriel Christopher Tiglao on February 26, at But then I looked at myself and asked – “am I an engineer or a soy boy?

Once the software is installed, follow the instructions below to send and receive packets:. There is a version of the project for the ZedBoard and the MicroZed. It seems that the standard is so old that everyone has already converged. All Ethernet devices are required to respond to ping requests, so this is a very simple and easy test to perform using your computer.

Lwup I submitted a small patch.

So I followed the instructions in the above link to set up the ethernet connection on my Windows PC with the static IP address SO,does anybody have any idea what I could be doing wrong please? If you are using Vivado As per the threads, it is a problem as it will not execute any necessary initialization MDIO clock, etc.

In the SDK we will be able to generate the echo server example design and run it on our hardware. The software that I use is called Packet Sender and can be downloaded here. At this point, the SDK loads and a hardware platform specification will be created for your design. Notify me of new posts by email. You will find the modified library files inside the EmbeddedSw directory of the repo. Soumya on September 19, at 4: There are a few reasons for these modifications, liwp we would be going off-track to discuss those reasons in detail at this point.


I have just tried turning on some of the debug options in the bsp and I am getting repeated warnings.

Solved: Cannot connect to lwIP echo server on Zynq – Community Forums

Firstly, for those of you who did not follow the first part of this tutorialwe will use the scripts in the Git repository for this project to regenerate the Vivado project. But then I hit this snag with the ethernet. These modifications are specific to using the echo server application on the Xioinx FMC. I think the Xilinx guys are going to support it soon.

Unfortunately when I come to connect via telnet using Putty, it tells me that the host is unreachable. Embedded Processor System Design: To change BSP settings: With the terminal program open, we can laip load our ZedBoard with the bitstream and then run the echo server application.

I will not answer to personal messages – use the forums instead. Once I removed this, I ran the application and I am now able to connect:. If you did not follow the first part of this lwwipyou may want to open the block diagram and get familiar with the design before continuing.
