I am trying to run the Echo Server demo on my Arty A7-100.  I am using Vivado 19.2 and Vitis.  I have the application loaded on the Arty and in my UART window it gives this message: It never gets to "TCP echo server started @ port 7".  I've changed the TEMAC adapter speed to 100, 10 and Auto-Negotiate and all have the same problem.  Any help is greatly appreciated.   Cheers
