EDK on Virtex4 FX using embedded ethernet MAC

Hello

I want to do a little EDK design that uses the embeded Tri-mode Ethernet MAC 
(TEMAC) of the Virtex4 FX parts. EDK offers several options for Ethernet MAC 
type but they are all soft MACs. The embedded MAC is a major selling point 
for me because of the logic saved and because compiling the soft MACs takes 
a long time. I will be connecting to a 10/100 switch using the MII port.

Is there a convenient way to incorporate the embedded MAC into an EDK 
project?

Thank you for any suggestions.

EDK 7.1 has a wrapper for the hard MAC.  And there's an update for that
wrapper downloadable from the Xilinx web site.

Hi Pete,
I'm working with  a Virtex4FX12 at moment, and I'm designing a dual
port Ethernet MAC (10/100/1000) for a VOIP application.

I started with the XAPP 807 that shows how to use ultracontroller2 with
a single MAC to have a simple webserver based on
uIP (uIP is a simplified TCP/IP stack).
(a TCP/IP stack in less then 16K... that is the size of the instruction
cache of the PPC405)

It works!!
I was impressed to see how easy was to implement the webserver.

I really reccomend you to start from here :-)

At moment I'm designing the TCP/IP stack in HDL....
If you don't like this idea then I suggest to use: the plb_temac (from
Xilinx Platform Studio go on Project->Add/Edit Cores...
and add the plb_temac)
Have a look at the PDF documantation .

good luck!

Francesco

Hi Pete,

Check out the Xilinx Gigabit System Reference Design (GSRD) at
http://www.xilinx.com/esp/wired/optical/xlnx_net/gsrd.htm  It uses the
Embedded Virtex4 TEMAC in an EDK project.

Can you get either xilnet or lwIP to work with it though?

For xilnet, in the library/OS parameters tab, I can't set the plb_temac
as the emac_instname (Only none is listed).

For lwIP, when generating libraries and BSPs, I get the error: lwIP
library needs at least 1 ethernet or 1 ethernetlite device to work.

I definetly have instantiated the plb_temac_0 and hard_temac_0 cores.

Any ideas?

Cheers,
Jon
