Okay give this is a shot. It runs on my board. This example uses the Avalon OpenCores 10/100 Ethernet MAC rather than the Altera TSE MAC.
I've included the SOF file in the ZIP file so you can just program it but you'll want to recompile the project to see how it's structured. I couldn't include the database files for size.
In order to recompile you'll also need the Avalon OpenCores MAC which is available here:
http://www.alteraforum.com/forum/showthread.php?t=3665 You'll need to unzip this in the
c:\altera\80\ip\sopc_builder_ip\ folder.
As far as the software goes. I've hard-coded the MAC address and set the static IP address to 192.168.1.50.
So to run it, you'll need to program the SOF into the board, then use the IDE to download and run the simple-socket server example. This example is running out of the SSRAM on the board.
