From: Pete on 20 Oct 2005 15:54 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. Pete Dudley

From: francesco_poderico on 21 Oct 2005 06:35 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

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 |
