Auto Negotiation FAILED : Nios II Simple Socket server

I have been trying to implement NIOS II simple socket server for Cyclone V GT from the reference design from the link: https://fpgacloud.intel.com/devstore/platform/16.0.0/Standard/nios-ii-simple-soc...

Hello Eliath,

Thank you for the fix that you have suggested regarding the name mismatch in the TSE_0. It worked. In the NIOS console, I was being asked to provide the 9 digit serial number present at the back of my board (refer to the screenshot). Is this normal? Because I did not come across this pop up when I was working with the reference design present in the website. Kindly guide us. @Eliath_G_Intel

Hello Eliath,

In one of the documents present in the website for NIOS II Simple socket server, it was mentioned that in case of issues related to MAC address, we can try typing "255255248".

I have typed that address and it seemed to be working. In fact, any non zero 9-digit address seems to be working. So It shows that the Simple socket server is listening in port no.30 as shown in the screenshot.

But now, when I am trying to open a Telnet server with the IP address 192.168.1.234 and port 30, the connection is not established. I've even tried with 192.168.1.1 but no success.

Kindly help.

Regards,

Avinash Paga

    Hello Avinash,

    We have two KDB's ( Knowledged Data Base) where you'll find the changes needed on the code to make the project work properly. The connection will be solved too.

    Why my Nios® II Simple Socket Server design example fails to auto-negotiate at 1G speed

    Why my Nios® II Simple Socket Server (RGMII) design example Ethernet link is down when run on Intel FPGA Development Kits with MARVELL PHY?

    Please, apply these changes to your code and test again the connection with the host.

    One more thing, when executing the windows command prompt, try to do it as administrator and then make the corresponding test.

    Any questions or updates, please do not hesitate and let me know. @APaga1

    Regards,

      Hello Eliath @Eliath_G_Intel ,

      Thank you for your support. We have observed that the auto negotiation is passing at 1G speed and the naming conventions of TSE are according to what it is suggested in the KDB that you have sent. But unfortunately, the ethernet link is still not up. We are getting the below message in the NIOS console at the end:

      ********************************************************************************************

      Simple Socket Server starting up
      [sss_task] Simple Socket Server listening on port 30
      Created "simple socket server" task (Prio: 4)

      ********************************************************************************************

      But still we could not establish a telnet session with IP: 192.168.1.234 and port 30. We are hardware engineers and we are finding it difficult to debug the software portion of the simple socket server. Can you please explain what can be a way to progress further? Thank You!

      Warm Regards,
