WORKING: DE2-115 Simple Socket Server

--- Quote Start ---

I used a cross-over cable and set the computer's IP address to 192.168.10.235, and the subnet mask and the gateway to the same value as the socket server.

Then, if you ping the Board's IP address 192.168.10.234, it should be successful.

Where do you have troubles?

Thanks for your reply,I have do the job as you say,but ping meet the problems as follows:

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

Pinging 192.168.10.234 with 32 bytes of data：

reply from 192.168.10.235 ：Can not access the target host

reply from 192.168.10.235 ：Can not access the target host

reply from 192.168.10.235 ：Can not access the target host

reply from 192.168.10.235 ：Can not access the target host

Ping statistics for 192.168.10.234 ：

Packets :Sent = 4, Received = 4, Lost = 0(0% loss),

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

at the same time, telnet still failed at the port 30.

Have you ever change the code in simple_socket_server.c or something else(especially the code about DHCP)?

I changed the http_send_file() function and I added the code that you gave me,however when I open the webpage it is generating the following error on the console: Error_handle_receive: error preparing response and on the webpage it is giving me:

error 324 (net::err_empty_response): the server closed the connection without sending any data.

And one more question please: why did the following statement generate error on tse (undefined variable):

strncpy(IP_Stat.MAC_Address,sprint_macaddr(macaddress),IP_ADDR_SIZE);

Thank you so much for your help!

Can you post the full output of NIOS? Does it say: "Auto-negotiation Failed" or "...Passed"?

The output of NIOS II is:

It seems that it should work, but the ping & telnet can't work, and the error i have show you previously.

Dear David, the ping and telnet are succeed when I use the DHCP server, but when I connect the board and PC with a cross-over cable, I failed.

DHCP in the BSPEditor is diabled, and I change some codes in Quartus II,as follows:

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

// ===== SOPC control signal defing

assign set_1000_to_the_tse_mac = 1'b1;

assign set_10_to_the_tse_mac = 1'b0;

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

hope for your reply.

I don't know what's going on. I think best would be, if you opened a new thread.

Hi,David

I open a new thread, and I meet the same problem. I can send words or command via Telnet or Ping, when I use a router. However, I always failed when I directly connect the board and PC with a cross-over cable. I am really confused, I hope that you could help me.

Can you send your software project to my email, then I can compare our code. My email --- [email protected]

Have a good day!

Thanks for posting your design. I cannot get your design running.

When I implement your design, I get the error:

undefined reference to 'tse_mac_device'

Specifically, the error lies in these two lines of code are indicated in the file altera_avalon_tse.c:

if(tse_mac_device.tse_mac_base == p_driver_data->hw_mac_base_addr) {

psys_info = &tse_mac_device;

Does anyone know how I can handle this error?

I can't see how I should build my own socket server, when the examples are not working. I can also use the DE4 board if that is easier.

Thanks

Hi, David and bjtuxuxu,

I'm facing the same problem now and really confused about how to make the telnet client access the cable connected to the board. My program just keeps listening but nerver get the request...... Could you please give me some suggestions about how to solve the problem ?

Really thanks for your help!!

You should set your PC to 1000Mbps full duplex.

And if you failed at ethernet0, then try ethernet1.

Good luck !

Hi all

after 2 weeks I can run the SSS application

thanks for providing the modified version for DE2-115

and thanks for all post , it was very helpful for me especially is my first nios II application !

but I cant only run the application with the DHCP

if I disable DHCP I get the following errors and the application won't build

1- void SSSInitialTask(void *task_data)

{

INT8U error_code;

system_dhcp_hostname = "NEEK_1";

wait_on_phy();

/*

* Register new DHCP "IP attained" callback function.

* If DHCP is acquired, ws_ipset will be called instead of dhc_main_ipset().

*/

dhc_set_callback( 0, ws_ipset ); // error

2- void SSSMonitorPhyTask(void *task_data)

{

//

//

//

dhc_set_state( 0, dhcs_initreboot );// error

any idea how to fix these 2 errors to connect FPGA directly to my PC

many thanks in advance
