DM9000A net port

I have a question about my ethernet port, the chip is DM9000A

when I download kernel by" nios2-download -g vmlinux" ,then enter as nios2:Uclinux,

the netport is ok sometimes, but it's bad sometimes.

When the port is bad, I use the list command to display someinformation.

Could you please tell me what happened and dow to do?

# ifconfig(2006,06,13)

lo Link encap:Local Loopback

inet addr:127.0.0.1 Mask:255.0.0.0

UP LOOPBACK RUNNING MTU:16436 Metric:1

RX packets:0 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:0

RX bytes:0 (0.0 http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif TX bytes:0 (0.0 http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif

# ifconfig eth0 192.168.168.2

SIOCSIFADDR: No such device

Thank you very much!

Best Regards!

    hi

    I think u need to download the file system also

    try to configure the net interface before downloading by changing one line in the :

    "/etc/rc" file.

    I hope it will run now !

    best regards
