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.

Once I removed this, I ran the application and I am now able to connect: If you enjoyed this tutorial or if you run into xiinx using it, please leave me a comment below. As per the threads, it is a problem as it will not execute any necessary initialization MDIO clock, etc.

The IP application in the second…. Please verify the initialization sequence link speed for phy address 1: Sukanya K on August 24, at Say, getting images from camera modules connected via ethernet and image processing is done in the FPGA? 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.

I had the Zybo for over an year – I love it because I can test and prototype small projects very fast with it. It is interesting that Digilent have the tutorial for the Zybo which makes no mention of this issue. Firstly, for those of you who did xiilnx follow the first part of this tutorialwe xiinx use the scripts in the Zilinx repository for this project to regenerate the Vivado project. This seems to be confirmed by the DHCP timeout in the serial output.


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. Ah I did not know that there was a problem with the Realtek chips. If you want to experiment, you can play around with the software by sending more packets, or different kinds of packets.

It appears that in xemacpsif. If so, this was already enabled when I created the application project from the template:. Your email address will not be published.

At this point, your SDK workspace should contain only the hardware description and no applications:. The BSP for this project will also have to lwiip modified slightly. When the bitstream has been generated, we can export it and the hardware description to the Software Development Kit SDK. Do you know if the Realtek chips were previously supported? But then I hit this snag with the ethernet.

xxilinx Accept as solution if your question was answered. Does anybody have any idea what I could be doing wrong please? Below are the links to the source code Git repositories.


I strongly recommend that you perform these modifications to the sources in the Vivado installation files — not the sources in the BSP of your SDK workspace. Noriel Christopher Tiglao on February 26, at dilinx Meanwhile I submitted a small patch.

You see that the chip is not any of the ones supported Marvell or TI.

SO,does anybody have any idea what I could be doing wrong please? All forum topics Previous Topic Next Topic. The PYNQ is telling my via serial comms that.

But then I looked at myself and asked – “am I an engineer or a soy xilind We want to add some code to the application to allow us to select a different port if we choose. I have just tried turning on some of the debug options in the bsp and I am getting pwip warnings. If you did not follow the first part of this tutorialyou may want to open the block diagram and get familiar with the design before continuing.
