VCU118 lwip echo

Hello 

I am using Microblaze Example design on vivado to test the lwip echo server.

I am not able to run echo server on VCU188 microblaze example design. 

 

i have read here that this is a know issue. 

https://www.xilinx.com/support/answers/68277.html

so i also made the design ( shown below) on one of the latest versions  i.e. vivado 2018.3.  it also doesnt work on this version. 

 

i read on the forum that i have to disable, autonegotiation, and fix to speed in lwip BSP settings. i also did it. 

and i also didnt work (console output is shown below). 

 

Could you please guide me how to make it work ? 

 

Best Regards

Rizwan
