USRP2 connection problem

Hi everyone,
I am using USRP2 on ubuntu 10.10. When i try to run it with grc i got
the
this message,*

Traceback (most recent call last):
File “/home/mehmet/top_block.py”, line 46, in
tb = top_block()
File “/home/mehmet/top_block.py”, line 29, in init
self.usrp2_sink_xxxx_0 = usrp2.sink_32fc()
File “/usr/lib/python2.6/dist-packages/gnuradio/usrp2.py”, line 1137,
in
sink_32fc
return _usrp2.sink_32fc(ifc, mac)
RuntimeError: No USRPs found on interface eth0*

then i run ifconfig eth0 command then i got,

*mehmet@mehmet-PC:~$ sudo ifconfig eth0
[sudo] password for mehmet:
eth0 Link encap:Ethernet HWaddr 60:eb:69:29:bb:c8

Interrupt:48 Base address:0x4000 *

finally i tried find_usrps but again no response,

mehmet@mehmet-PC:~$ sudo find_usrps
No USRP2 found.

I have checked if i install sdcc compiler from synaptic package manager
and
it seems it is installed.
I use the ethernet cable that comes with usrp2 in the package. then i
changed the ethernet cable.
I used the one that is for internet connection but it didn’t work.

The screenshot of the basic grc problem is attached.

Thanks for your help.

Mehmet

Hi Adrew,

I used wireshark instead of tcpdump and see something on the screen
but don’t understand what they mean. As i read wireshark shows if we
send and receive packet to/from any device.But i see that i can send
and receive packets via eth0 by using ifconfig,

mehmet@mehmet-PC:~$ sudo ifconfig eth0
[sudo] password for mehmet:

Hi Eduardo,

I use HP pavilion dv6 core i7, and i checked the ethernet card it
supports the gigabit ethernet.

Do you have any other ideas why this could be happen?

Thanks a lot.

Mehmet.

Hi everyone,

I solved the problem about the USRP2 connection.
The problem was the fgpa and firmware images.
My mistake was burning UDP images on this link to the SD card which
are for experimental usage
http://code.ettus.com/redmine/ettus/projects/public/wiki/U2binaries

I changed the images to raw ethernet and everything worked fine.

Thanks everyone for your help.

Mehmet.
