Hello, I'm new to using GNURadio and the USRP.
I'm running Fedora 17 with GNURadio (3.5.3.1) and UHD (3.4.3) installed with yum.
I'm trying to run uhd_fft.py and I get the following error:
$ ./uhd_fft.py
linux; GNU C++ version 4.7.0 20120507 (Red Hat 4.7.0-5); Boost_104800; UHD_003.004.003-0-unknown
Using Volk machine: sse4_1_64_orc
Traceback (most recent call last):
File "./uhd_fft.py", line 180, in <module>
tb = uhd_fft(gain=options.gain, freq=options.freq, address=options.address, samp_rate=options.samp_rate)
File "./uhd_fft.py", line 110, in __init__
channels=range(1),

return _uhd_swig.usrp_source(*args)
RuntimeError: send_to: Network is unreachable
I'm wondering if there is a mismatch on my UHD driver and the firmware/fpga images?
Because when I do:
$ uhd_find_devices
linux; GNU C++ version 4.7.0 20120507 (Red Hat 4.7.0-5); Boost_104800; UHD_003.004.003-0-unknown
No UHD Devices Found
BUT:
$ uhd_find_devices --args="addr=192.168.10.2"
linux; GNU C++ version 4.7.0 20120507 (Red Hat 4.7.0-5); Boost_104800; UHD_003.004.003-0-unknown
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
type: usrp2
addr: 192.168.10.2
name:
serial:
E0R22N8UP
A similar thing happens when I run 'uhd_usrp_probe' ... if I do not specify the address then nothing is found, but if I supply the IP address then it prints out information that looks good.
I can ping 192.168.10.2 successfully as well.
Any ideas?
Thanks
