simple socket server connection established, but cannot ping/telnet

hello guys,

I got a problem with simple socket server problem. I post similiar thread in dev kit forum, but no answer until now. I am thinking maybe I could get help from here. Thank you in advance.

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_cycl oneIII_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]=0xB7;

mac_addr[1]=0xA7;

mac_addr[2]=0xED;

mac_addr[3]=0xFF;

mac_addr[4]=0xFF;

mac_addr[5]=0xFF;

return 0;

// return (get_board_mac_addr(mac_addr));

}

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

6. I disable DHCP in wizard and I use cross cable to connect board and PC directly.

7. 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.
