Hi,
I installed GNUradio on my laptop with the build-gnuradio script
(http://www.sbrac.org/files/build-gnuradio). As far as I know GNUradio
is working. I’m able to run dial_tone.py and completed some tutorial
using some download data.
Now that I got a USRP n210, I want to start using it, but it seems that
my laptop cannot detect the USRP. When I run uhd_find_devices, this is
what I get:
linux; GNU C++ version 4.6.3 20120306 (Red Hat 4.6.3-2); Boost_104700;
UHD_003.004.002-128-g12f7a5c9
No UHD Devices Found
When I try to run uhd_fft.grc, I get:
linux; GNU C++ version 4.6.3 20120306 (Red Hat 4.6.3-2); Boost_104700;
UHD_003.004.002-128-g12f7a5c9
Using Volk machine: sse4_2_64

RuntimeError: LookupError: KeyError: No devices found for ----->
Device Address:
addr: 192.168.11.2
I have tried setting the address to 192.168.10.1, but I don’t think that
changed the address of my ethernet port because when I checked my
connection information the IP address was different. Also setting my
address to 192.168.11.2 did not help either.
I am using Fedora 16 XFCE, and I have confirmed that I do have gigabyte
ethernet using ifconfig.
Any help is appreciated,
Frederick
