SDK - "lwIP echo server" - Unknown PHY link speed

Hi, 

 

 I'm using a Kintex-7 series device (xc7k325t-2ffg900) along with ISE 14.7 and I have created a XPS design:

In SDK I can successully run the "Memory Tests" application.

 

However, when I run the "lwIP echo server" application, the application is NOT able to detect the PHY linker speed:

What I find a bit strange is that I am able to detect the PHY link speed using in a XPS design that was initially created using ISE 13.4 and then migrated to ISE 14.7 (the "lwIP echo server" was also initially created using ISE 13.4).

 

However, if I create a new "lwIP echo server" application in SDK for that same migrated design, it is NOT able to detect the PHY link speed.

 

 

So can anyone tell me whats needs to be changed in order to make it possible to detect the PHY link speed for the design created using ISE 14.7?

What PHY do you have?

The autodetect only works for Marvell PHYs on Xilinx Eval boards. You might want to change the speed manually.

Re: SDK - "lwIP echo server" - Unknown PHY link speed

My board uses Marvell PHY, I set the CONFIG_LINKSPEED_AUTODETECT.  When I tried to change the values to 10/100/1000 it continues with the "TCP echo server started @ PORT 7" but still can't ping the device.

Re: SDK - "lwIP echo server" - Unknown PHY link speed

How do you ping the device? I usually use a telnet session in teraterm.

 

1. In the New connection dialog box, select the following options

TCP/IP: Selected

Host: 192.168.1.10 (IP address of your device)

History: De-Selected

TCP port#: 7

Service: Telnet

 

2. Click OK

 

3. Setup > Terminal

Terminal: CR+LF

 

4. Click OK.

 

5. Setup > Save Setup

 

Also, check if the packets are coming through using wireshark.
