I have been working with the CycloneIII Development board (EP3C120) using QuartusII 9.1sp2 with the project daixiwen (http://alteraforums.com/forum/member.php?u=4443) linked at: http://alteraforums.com/forum/showthread.php?p=90831#post90831 I created the NIOS template project Simple Socket Server and am having problems with connecting to the server through telnet. The only modification required to compile was Enabling the NicheStack component in System Library Settings. I connect the ethernet cable from the development board to my computer and run the NIOS. once running the console displays: Copyright 1996-2008 by InterNiche Technologies. All rights reserved. prep_tse_mac 0 Your Ethernet MAC address is 00:07:ed:ff:c2:95 prepped 1 interface, initializing...

more preliminary troubleshooting. Using wireshark, i can verify that my PC is querying for 192.168.1.234. I can also see the "Rx LED" light up on the development board each time my PC sends a ping request. this leads me to believe that there might be some issue with the NicheStack accessing the SGDMA module

The first thing you should see in Wireshark is an ARP request. Something like "who is 192.168.1.234? Tell x.x.x.x". Do you get an ARP reply from the board giving its mac address? Did you do any modification or recompilation to the Quartus design, or are you using the .sof file provided with the project by Altera?

I did see the arp request but no response from the development board. I did compile the FPGA project. I will look for and try the pre-compiled sof file on Monday.

Do you have the license for the TSE? If not, be sure not to close the Opencores evaluation window. It would make the TSE stop working.

I am seeing the same behavior on the seme dev kit running the same app under 9.1_sp1... I have a license file that says the tse nios, etc is present, however upon telnet I do not see the house of cards collapse, rather the system simply appears to be hung. Would love to work through this with all of you and perhaps post our fixes here for others rather than the typical "I got it - thanks" or the "dead-thread" that is all too prevalent on sites like this...

Seems like my code is getting to the blocking select() below and hanging... wondering what is happening or not happening - anyone?

FD_ZERO(&readfds);
FD_SET(fd_listen, &readfds);
max_socket = fd_listen+1;

if (conn.fd != -1)
{
FD_SET(conn.fd, &readfds);
if (max_socket <= conn.fd)
{
max_socket = conn.fd+1;
}
}

select(max_socket, &readfds, NULL, NULL, NULL);

I'm using Quartus/Nios 9.0 and know it works...

I too had some trouble with hangs in select() calls, and had to change a define in ipport.h. Have a look at this message (http://www.alteraforum.com/forum/showpost.php?p=76102&postcount=5).
I'm not sure this "cure" works with 9.1 though...

i tried uncommenting the define you mentioned and recompiled and got this:

looks like this causes: multiple definition of `tcp_wakeup()' and `tcp_wakeup()' as these were originally defined in tk_crnos.c but when using this define they are redefined in netmain.c

Guys I too face the similar problem.
Go through the attached snapshot of error and suggest me the solution

fire a debugger and put a breakpoint on dtrap() to see what is causing it.

Hi folks,
I am using Arria II GX on my custom board
I am making my custom board as CLIENT and one host PC as SERVER to establish communication between client and server using socket programming.
I am using MARVELL PHY 88E1111 on my custom board, Triple Speed Ethernet MAC in my SOPC builder design
I have attached snapshot of my SOPC bulider design, Please go through it and let me know if any problem in SOPC builder design.

I created a client program in Nios II SBT for Eclipse and tried to run as hardware on my custom board.
I am able to configure my custom board with static IP address, I can ping my custom board successfully with the IP address I configured.
socket gets created on the board, after this client program on custom board tries to connect to server on my PC, but.....
connect never happens....
I have also attached snapshot of whatever I see in NIOS II console.
sometimes I get error message as
dtrap - needs breakpoint
panic: pktdemux: corrupt pkt
dtrap: needs breakpoint
ip_exit: calling func 0x1141eb30
netclose: closing iface Altera TSE MAC Ehernet
ip_exit: calling func 0x114126ef0
well sometimes I get error as
No free buffers for rx
No free buffers for rx

put a breakpoint on the dtrap() function and use the debugger to find out where the call came from. If you are lucky you may find a helpful comment in the code saying why dtrap() was called.
And don't post the same question multiple times
