Simple Socket Server problem

Hi All,

I tried to run simple socket server example with full_featured 1S10ES example. However, whenever [after downloading the sof file using Quartus Programmer] I click on [after selecting simple_socket_server_0 in project navigator] Run As --> NIOS Hardware, I get the following message:

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

nios2-terminal: Warning: The JTAG cable you are using is not supported for Nios

nios2-terminal: II systems. You may experience intermittent JTAG communication

nios2-terminal: failures with this cable. Please use a USB Blaster revision B

nios2-terminal: cable or another supported cable. Please refer to the file

nios2-terminal: errata.txt included in the Nios II development kit documents

nios2-terminal: directory for more information.

nios2-terminal: connected to hardware target using JTAG UART on cable

nios2-terminal: "ByteBlasterII [LPT1]", device 1, instance 0

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

//My ByteBlaster II cable works fine, so I doubt if that may be a problem//

Simple Socket Server starting up

Your Ethernet MAC address is 00:07:ed:0a:a5:9e

//at this stage seven-seg shows random patterns. But when following messages appear, it gets fixed at "97"//

[lwIP]: See STDERR (FAULT_LEVEL is SYSTEM).

[lwIP]: FAULT_LEVEL is SYSTEM.

[lwIP]: FATAL Error, Restart required.

Also, as asked in the above messages, where do I see STDERR?

    Hi,

    usually, the jtag_uart is used for stdin, stdout and stderr. Refer to the system library settings in your project properties (IDE).

    The error, you get, is caused during the excecution of lwip_devices_init(...). You can find this function in alt_lwip_dev.c

    May be, you should check the processing of this function to determine the cause of the error!

    Hey

    Did you install the Updated Ethernet Driver for NIOS which i think comes with the socket code.

    I had the same issue on my 1s10

    STDERR needs to be set to jtag_uart (same as STDOUT)

    regards

    Make sure, you did not change the name of the lan-adapter in your SOPC-Builder system. Easiest way to keep things running is to leave your network-adapter named lan91c111.

    hmm, I had something similar. But then I noticed, I had forgotten to check under properties system library for software components: add software. IP.. have look at the light_weight_ip tutorial.pdf.

    &#39;hope I could help you.
