simple socket server connection established, but cannot ping/telnet

[Altera_Forum]

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:  =============== Software License Reminder ================ This software project uses an unlicensed version of the NicheStack TCP/IP Network Stack - Nios II Edition.

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?

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  Regards

I have the same problem with you,dubuging server weeks but without any result,have you find the selution ?

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);

[Altera_Forum]

I have the same problem! :confused: 

Has anyone found a solution?

[Altera_Forum]

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

[Altera_Forum]

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!!!!

[Altera_Forum]

try Quartus 9.0 & IDE 

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

[Altera_Forum]

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.

[Altera_Forum]

Terasic have managed to fix my problem. 

They supplied this file which allows for compilation in Quartus and SOPC Builder 10.0 SP1.  In Nios II EDS 10.0, I created a Simple Socket Server example as per the .SOPCINFO file generated from the downloaded files. I then had to copy the files from the QB3/QB3_NET_GMII_NET0/software/ethernet_test/simple_socket_server to overwrite the files in my project. I applied the changes as per the HSMC-NET user manual, and finally it works!

[Altera_Forum]

I'm glad that you've fixed your problem. 

have you compared the files they gave you with your own? is it about the marvell_cfg_gmii?

[Altera_Forum]

I compared most of the .v files (to compare the hardware) and most of the .c files (to compare the software) and cannot seem to find any differences. 

I added the "marvell_cfg_gmii(tse[iface].mi.base);" line to both ins_tse_mac.c files in both projects, so the difference isn't there.

[Altera_Forum]

just an fyi ... i've been fighting this problem for most of the morning. the suggestion made by 

seilaser did the trick. i simply left the quartus-ii programmer open and i can ping as well as run the telnet example.   /david

Hi guys, 

I am also facing the same problem. I am using Arria II GX FPGA on my custom board. Marvell 88E1111 PHY, TSE MAC and RGMII I m using version 10.1  I am not able ping the custom board.  @t.yuan Where exactly shall I include "marvell_cfg_gmii(tse[iface].mi.base);" in ins_tse_mac.c  my interface standard is RGMII   @BenjaminLunsky What exactly u did? can u elaborate? What files you got from Terasic? can u please tell me?   URGENT !!!!!!

Hi, 

I am using Arria II GX FPGA on my custom board. Marvell 88E1111 PHY, TSE MAC and RGMII I m using Quartus version 10.1  I am trying to run Simple Socket Server with RGMII mode on my custom board. I am able to ping my custom board with th IP address I configured on it.  But connection establishment between client and server is not happening Do I need to include marvell_cfg_rgmii(tse[iface].mi.base); in ins_tse_mac.c  Where exactly shall I include "marvell_cfg_gmii(tse[iface].mi.base);" in ins_tse_mac.c  What can be other possible solution?

[Altera_Forum]

If you can ping the board, there's definitely no problem at the mac/phy levels, so I don't think you need to include that. 

Probably you have a wrong SSS code or made a mistake in tcp configuration: infact ping relies on UDP, while the server-client connection requires TCP which is a bit more complex. Using a network analyzer like Wireshark can easily help you to find out if connection initiates and where it fails before being established.

 I tried to rum same SSS code on Arria II GX development kit. It's running there on dev kit
