I'm trying to run the 1G eth UDP/IP Stack (from the Projects) section on my SP601 board.
bud I can't get it to work.

doe's anyone have an tutorial about how to do this?

Same question as yours.

Is there anyone can tell me how to implement it? I am a newbie and I need suggestion.

Many thanks,

Have you tried implementing the top module on the board and test a simple communication between it and the PC ? I saw that there are some Java UDP test files in a subfolder of the project package.

Hi, I have written a top file to test the UDP_IP_Core with virtex-5 (XUPV5-LX110T) board. The attached file is the top file. After I generated the bit file from the top file and downloaded the bit file into Virtex-5 board. The transmission led (TX LED) always lights. However I can't receive any data from Virtx-5 board. I already opened the port(21845 and 21844) on my pc. But still I can not receive any data. Could you give some suggestion or check the top file for me? Thanks so much.

As far as I know, at first, an ARP record is required to add into the arp table.
For example, your host pc's ip address is The assumed ip address
of the FPGA is, which is to be used in the java program.
Then execute
arp -s 00-aa-00-62-xx(MAC-Address of Ethernet Chip within the FPGA).

Then, develop a program. Either Java or C socket is ok.
Use as the destination address to send data or the source destination to receive data.
Attention, the UDP ports used by the pc program must be the same with the udp ports
predefined in the look up table of in the UDP/IP core. I believe you have noticed that point.

I hope this will help. Contact me by sunieforever At gamil dot com if necessary.
