simple socket server is simple, but still need help

Hi all,

Thanks for reading this thread, hope you could help me out.

My situation is here:

hardware: cIII 120 develop board

software: QII 9.1 sp2, Nios II 9.1 sp2

What i have done:

1. copy the C:\altera\91\nios2eds\examples\verilog\niosII_cycloneIII_3c120\triple_speed_ethernet_design to my project fold and open with QII

2. open sopc builder and run generate

3. back to QII and compile to generate sof (time limited version)

4. open nios eclipse ide, create a new project with simple socket server template

5. to avoid troulbe, modife get_mac_addr() as:

******************************************

int get_mac_addr(NET net, unsigned char mac_addr[6])

{

mac_addr[0]='0';

mac_addr[1]='0';

mac_addr[2]='0';

mac_addr[3]='0';

mac_addr[4]='0';

mac_addr[5]='0';

return 0;

// return (get_board_mac_addr(mac_addr));

}

******************************************

6. run app as "Nios II hardware"

what I got:

Everything looks smooth, but I cannot ping, telnet or whatever else.

When I ping, the RX light is flashing, but TX light not.

So, if you know something about this, please reply.

Thank you.
