to communicate fpga board to pc via ethernet

[kashyap0]

hi

i am trying to cummunicate to pc with fpga board. i am using atlys board of digilent company in which spartan-6 (xc6slx45csg324c) is connected to marevell 88E1111 phy chip.In this project i am facing the problem to getting the mac address of board (phy chip) to send the arp frame and udp frame.because i am manually framming the udp and arp frame fr in my code for which i need source mac address i.e mac address of fpga board (or marvell phy chip).

please respond me as soon as possible.

 

 

 

constant udp_frameA :frame60:=

(x"FF",x"FF",x"FF",x"FF", -- mac dest

x"FF",x"FF",x"00",x"00", 

x"00",x"04",x"14",x"13", -- i want to know this source mac address.

x"08",x"00",x"45",x"00", -- IP header

x"00",x"2E",x"00",x"00",

x"00",x"00",x"40",x"11",

x"7A",x"C0",x"00",x"00", -- IP src

x"00",x"00",x"FF",x"FF", -- IP dest

x"FF",x"FF",x"00",x"00", -- port src

x"50",x"DA",x"00",x"12", -- port dest + len 

x"00",x"00",x"41",x"41", -- checksum udp + data "A"

x"41",x"41",x"41",x"41",

x"41",x"41",x"41",x"41",

x"41",x"41",x"41",x"41",

x"41",x"41",x"41",x"41");

I don't know about the Atlys board's assigned MAC, but under VMware you can pick a random MAC address in the 00:50:56:00:00:00 through 00:50:56:3F:FF:FF. range.

 

If you don't have any VMware systems in the mix, you could just do the same.
