Hello everyone,

I am working in spartan3e with EDK11.1. I have succesfully sent data from  board to pc via ethernet using emaclite.I noticed the packet in my pc by wireshark.

Now i want to receive data from pc to board via ethernet?what function should i use?Can this similar approach be used by connecting the to board via ethernet.

any idea,plz share....

regards

Hieee

I want to add some specification like that

I have used    XEmacLite_SendFrame; to send a fram from board to pc and that succesfully happend.Now there are similar function like    XEmacLite_RecvFrame now will this fuction be used for sending pc to board.From where the recv_frame will expect to receive the frame?

Hey Tusu,

have you looked at XAPP1026.

http://www.xilinx.com/support/documentation/application_notes/xapp1026.pdf

This steps through echo server, Web server,TFTP server and receive and transmit throughput tests.

I think lwip is not available in spartan 3e.

is there any other way for board board to communication by ethernet port in spartan3e(XC350,FG320)?

As long as your design includes a timer, memory, interrupt controller and ethernet controller, lwip should be available.

Create a design using base system builder and use plb. Once you have your system, export it to SDK. In sdk, create a new C application and chose LWIP Echo Server from the template options.

how i receive data frame into board without using lwip?

[rourabpaul]

let me descibe how i send dataframe to pc

i have set a data frame of 42 cell 1st

u8 FramePtr[42]={0xff, 0xff, 0xff, 0xff,0xff,0xff,
0x00,0x00, 0x5E,0x00, 0xFA, 0xCf,
0x08, 0x06, 0x00, 0x01,0x08,0x00,
0x06,0x04, 0x00, 0x01, 0x00,0x00,
0x5e,0x00, 0xfa, 0xce,0xac, 0x10,
0x01,0x01, 0x00, 0x00, 0x00,0x00,
0x00,0x00, 0xac, 0x10, 0x01,0x7d};

 set a a arbitary mac address in spartan3e board like

static u8 LocalAddress[XEL_MAC_ADDR_SIZE] =
{
0x00,0x00,0x5E,0x00,0xFA,0xCE
};

then use 

XEmacLite_SetMacAddress(&EmacLitePtr,LocalAddress); 

and then send the FramePtr

XEmacLite_SendFrame(XPAR_ETHERNET_MAC_BASEADDR, &FramePtr);

I got my desire frame of 42 length on wire shark

But 

now i want to communicate 2 board
sender Board  is unchanged with above code

but in reciver board i set another arbitary mac address like  

static u8 LocalAddress[XEL_MAC_ADDR_SIZE] =
{
0x00,0x00,0x5E,0x00,0xFA,0xCF

};

and initialize another array

u8 RecevBufr[42]={0x00, 0x00, 0x00, 0x00,0x00,0x00,
0x00,0x00, 0x00,0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00,0x00,0x00,
0x00, 0x00, 0x00, 0x00, 0x00,0x00,
0x00, 0x00, 0x00, 0x00,0x00, 0x00,
0x00, 0x00, 0x00, 0x00,0x00, 0x00,
0x00, 0x00, 0x00, 0x00,0x00, 0x00};

and use 

a=XEmacLite_RecvFrame(XPAR_ETHERNET_MAC_BASEADDR, &RecevBufr); // where 'a' is a 32 bit integer

and then print the 

for(i=0;i<43;i++)
{
xil_printf("\n %d th Recive.......%x\n\r",i+1,RecevBufr[i]);
}
print("-- Exiting main() --\r\n");

but i did not get my  FramePtr[42] in hyperterminal in recievber end

[rourabpaul]

is there any one????

[tusu]

Yes i have the same problem as of rourabpaul..can any one clarify that whether the two spartan 3e board could be connected via ethernet?When the ethernet port of spartan 3e board will blink?if the port doesnot blink does it mean that my emac core is not successfully downloaded?

next i would like to ask  form where i will get the reference design of Lwip?

plz share///

i think we need some delay before send frame and receive frame.

am I right?
