Hi,

I am trying to send data from PC to Spartan 3E Starter kit board (Rev-D) through a p-to-p ethernet interface.

I had used lwip software stack and echo server and was able to ping. Using telnet, I could find the echo server replying back to the request.

Now, I would like the Microblaze processor to fetch the packets from ethernetlite core and process it. When I add the following code snippet post xemacif_input(netif) in the infinite while loop, I don't find the server to respond to my ping request.

while (1) {

xemacif_input(netif);

transfer_data();

}

int transfer_data() {

xil_printf("Echo server is replying back the data \n");

Xuint16 data16;

Xuint8 *FramePtr = 0x00000000;

data16 = XEmacLite_SendFrame(XPAR_ETHERNET_MAC_BASEADDR, FramePtr, );

return 0;

}

I guess I am missing something very trivial. Would really appreciate if you could let me know what the problem is and probably pointers to sample codes using XEmacLite_SendFrame.

Thanks!
