Dear all:
I am trying to run seom example codes on USRP. My computer equipes USB
1.1. I use Fedora Core 7 + python 2.5 + gnuradio 3.0.3 to bulid the GNU
Radio. I had followed http://gnuradio.org/trac/wiki/BuildGuide to bulid
the GNU Radio. However, when I run tunnel.py to build physical setting
for WiFi, I type following commands:
python tunnel.py -v -f 2400E6 --bitrate 50k -i 32 -d 16
some errors occur as follows:
File “tunnel.py”, line 288, in
main()
File “tunnel.py”, line 249, in main
options)
File “tunnel.py”, line 95, in init
self.txpath = transmit_path(self, mod_class, options)
File
“/usr/src/CR/gnuradio-3.0.3/gnuradio-examples/python/digital/transmit_path.py”,
line 61, in init
self._setup_usrp_sink()
File
“/usr/src/CR/gnuradio-3.0.3/gnuradio-examples/python/digital/transmit_path.py”,
line 110, in _setup_usrp_sink
fusb_nblocks=self._fusb_nblocks)
File “/usr/local/lib/python2.5/site-packages/gnuradio/usrp.py”, line
209, in init
_ensure_rev2(which)
File “/usr/local/lib/python2.5/site-packages/gnuradio/usrp.py”, line
82, in _ensure_rev2
v = _look_for_usrp(which)
File “/usr/local/lib/python2.5/site-packages/gnuradio/usrp.py”, line
76, in _look_for_usrp
raise RuntimeError, “Unable to find USRP #%d” % (which,)
RuntimeError: Unable to find USRP #0
I guess that the usb maybe cannot understand USRP platform.
Could you give me some help?
Best Regard
