eth0 not found

I am trying to bring up the Ethernet interface of my DE2 board, but it keeps me showing "SIOCSIFADDR: No such device" when I ifconfig it.

I followed every step of the tutorial and I am using the uClinux-dist-test-20060511.tar.bz2 with only the uClinux-dist.diff.gz patch.

Is there something wrong with this kernel? I am starting to think it could be a hardware problem, cause my board's ethernet connector leds do not turn on when I plug the network cable.

Following are the system messages:

    Hi,

    make sure that when you are defining the Nios system using SOPC builder the LAN device is not assigned the IRQ no 0. Better make it more than 2 as sometimes I face problems when IRQ is defined less than 2.

    I assigned IRQ 4. Do you have any other suggestion?

    Thanks

    Dear Alair,

    I haven&#39;t solved the problem thoroughly.

    Before, I change the DM9000A, then it&#39;s ok! but some days later, it bad again. So I&#39;m puzzled. Now I don&#39;t have a gpood idea!

    Best Regards!

    I have figured out what was wrong just after a good night of sleep. It&#39;s amazing how things get clear when you have a shower. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

    I had forgotten to provide the proper clock to ENET_CLK signal! I knew I was missing something. Pehaps you are missing the same thing. Be careful of how you implement this clock. I did as follow and everything went ok: 

    -- SOME CODE HERE
-- ...
SIGNAL tmpClk : STD_LOGIC := &#39;0&#39;;
BEGIN
    -- ENET CLOCK (25MHz)
    tmpClk <= NOT tmpClk WHEN CLOCK_50&#39;EVENT AND CLOCK_50 = &#39;1&#39;;
    ENET_CLK <= tmpClk;
-- MORE CODE HERE
-- ...

    You can make this code without the tmpClk signal, I did it just for readability, but be sure of initialize the signal with "0" or &#39;1&#39; before applying the NOT operator.

    I also had a look at the uCLinux source and changed my IRQ to 3 as well. This is the default IRQ for DM9000 and I thought it would avoid later problems.

    Good luck!!

    the FPGA: EP2S90,the ethernet is LAN91C111,use the nios "simple_socket_server" to test

    Okay, it is the correct driver. The message seems to indicate that there is a problem with initialization of the chip. Is it your own FPGA design or are you using one supplied with the kit?

    it's my own own FPGA design .you said "there is a problem with initialization of the chip", you mean the chip is EP2S90 or LAN91C111.

    thank you very much.

    I meant the LAN91C111. Can you try a .ptf/.sof combination provided with the kit? That way you'll know if the problem is from the hardware or the FPGA design.
