Zybo Ethernet example

[alonzo]

Hello,

I have tried to build an Echo Server on Zybo using example from SDK.

Because I could not find any hardware examples I followed this one for Arty: https://reference.digilentinc.com/learn/programmable-logic/tutorials/arty-getting-started-with-microblaze-servers/start

I just customized it for Zybo and used Zynq instead of Microblaze. I uploaded the program on my Zybo but Echo server does not work because every time I try to communicate with it I get the timeout.

I have read on this forum that it is possible to design Zynq processing system (with Ethernet enabled) as hardware and then the SDK example should work. But I have difficulties in designing the processing system itself because it will not generate a bitstream.

Is there a step by step example on how to design the processing system for Zybo or how to set Ethernet interface on Zybo?

I would really appreciate any suggestions.

 

I work on Vivado 2015.4

Best regards

Piotr

Hi Piotr,

Here is a thread that has some options for setting up a server on a zybo. Hope this helps!

Dear Jon

Thank You for quick response! I will look at this thread.

If you build a Zybo design from scratch you have to change the emio to mio for the Ethernet or wilt will not work.

It defaults to emio
