Problems Using LwIP Xilinx SDK Example

Former Member
Former Member over 12 years ago

Let me start by saying I am completely new to the Zynq world and am learning very slowly on this, but nonetheless, I am trying my best. 

First off, I have created a BSP and created an application in the SDK that was made from the LwIP example.  I have built it, programmed the Zynq on the Zedboard.  I have the serial port (Zedboard's USB-to-serial interface) monitoring the progress of everything, while I am receiving data that is telling me:

-----lwIP TCP echo server ------
TCP packets sent to port 6001 will be echoed back
Board IP: 192.168.1.10
Netmask : 255.255.255.0
Gateway : 192.168.1.1
Start PHY autonegotiation
Waiting for PHY to complete autonegotiation.
autonegotiation complete
link speed: 1000
TCP echo server started @ port 7

When I connect my Zedboard via a cross-over Ethernet cable directly to my PC's Ethernet jack, I then get this message in its entirety. 

I then attempted to open up a second Teraterm window to communicate with the TCP echo server.  I specify the IP as 192.168.1.10, check the Telnet radio control and specify to use port 7, then finally try to connect.  For some unknown reason, Teraterm keeps telling me that the connection is refused and shuts down.  I turned off my PC's firewall so that shouldn't be the issue I hoped, but this doesn't alleviate the issue at all - ineffectual.  This is pretty much where I am at...  I am stuck here and thought someone might have to give me some ideas of what to check for so I can progress with my learning. 

Much appreciate the help!  Thanks in advance!

    Would someone please take a look at this.  A link, document, anything!  Ask a question...  I don't care.  I need to figure out how to use this Zynq SoC somehow...
