Subject: [Discuss-gnuradio] 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
<module> 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,
address@hidden:~$ sudo
ifconfig eth0 [sudo] password for mehmet:
eth0 Link encap:Ethernet HWaddr
60:eb:69:29:bb:c8

finally i tried find_usrps but again no
response,
address@hidden:~$ 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
