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:

    The output log shows that apparently everything is ok:

    - application is running

    - ethernet link is established and nios is aware of it

    - tcp/ip stack has started and is operating

    - server ip address has been assigned

    - your application has started too and it is waiting a connection

    A few basic (and maybe silly) questions:

    - is your client (PC) configured with the correct subnet

    - is your application still running or is it stuck somewhere?

    - have you already made any debug? I mean, has the server application returned from the select() call?

    hi SIELASER,

    thank you so much for reply.

    my client PC is configred as:

    static IP: 192.168.1.235

    subnet: 255.255.255.0

    Default gateway: 192.168.1.1

    Board is configred as:# define IPADDR0 192# define IPADDR1 168# define IPADDR2 1# define IPADDR3 234# define GWADDR0 192# define GWADDR1 168# define GWADDR2 1# define GWADDR3 1# define MSKADDR0 255# define MSKADDR1 255# define MSKADDR2 255# define MSKADDR3 0

    I used cross cable to connect them directly.

    I did

    1. load sof to board(it is a timelimited file recated by QII)

    2. from IDE, load server application by "run as Nios II hardware"

    after load and print info to IDE,

    the server is waitting there.

    Then I try to ping from pc command line, by

    ping 192.168.1.234

    I found the RX light blink sometime, but TX is quiet.

    the server looks still waitting, nothing happen.

    after a while, ping is failed

    No, I didn't do any debug, no return from select() call, the sever is just waitting

    This shows that everything is ok up to the phy level.

    So you don't have any problem with ethernet link or cable.

    The problem can be due to the MAC, the sgdma or even the tcp stack.

    This is strange if you simply rebuilt a ready made reference design, without any change (this is what I think you did; is it correct?)

    I use a different dev board so I don't know if there is any hardware issue with yours.

    The only suggestion I can now think is that you can exclude tcp stack and check if raw ethernet frames are received: in the tse driver there is a function where all ethernet data is passing through. Unfortunately I can't remember its name; try locating arp_recv (or something like that), place a breakpoint in debug mode and then go backward until you find a function which filters some data.

    If you possibly find that no raw frame is received you have a problem with mac or sgdma configuration.

    One last idea:

    I see now that you are using a time limited version of sof file. Maybe you are using the OpenCore tse? In this case you should keep the connection with the programmer open or the tse core will stop working: don't close the reminder message box which appears after fpga configuration

    maybe you forgot to enable the GMII interface.

    try to add following code in the ins_tse_mac.c

    marvell_cfg_gmii(tse[iface].mi.base);

    I had the same problem using the board DMB3c40. I have a project with the next settings:

    QuartusII 8.0 sp1

    NIOS EDS 8.0

    NIOS FAST

    TSE_MAC 10_100

    simple_sockect_server sending video by using UDP sockets

    To solve this problem I had to change the setting Speed in my NIC card:

    I set: speed=100Mbits full duplex instead of 'autonegotiation'

    After this data were sent

    I am having the same problem using the Cyclone III Starter Board (3c25) and the HSMC-NET Daughter card.

    If I run the demo batch file (which installs the .sof and .elf file that came with the daughter card) then I can connect to the socket as shown in the tutorial.

    However if I compile the project myself (SOPC, then Quartus, then NIOS II EDS), it connects in the same way and the output on the NIOS console is identical, but I get no response when pinging the IP address and I cannot connect to the socket.

    I have tried this using Quartus and Nios versions 8, 9.1 and 10. Same results every time.

    Help please!!!!

    try Quartus 9.0 & IDE

    if it doesnt work, try to add your own .sdc file to constraint tx & rx clk.

    Ok thanks. I'll download it and give it a shot.

    Please be more specific with what I should do with the .sdc file? I'm quite new to the timing constraint side of things.

    Forgot to add to my original post:

    I contacted Terasic about this issue, and told them how I went about Generating system in SOPC Builder, Compiling in Quartus 10 and then using Nios EDS 10. They said they tried the same thing and it worked perfectly for them. Really strange.
