Hi all,
I got a problem on opening usrp, but this program and the usrp worked well
before. The error message is as below:
e...@ubuntu:~$ usrp_sounder.py -t -f 3M
write_internal_ram failed: error sending control message: Protocol error
usrp: failed to load firmware /usr/local/share/usrp/rev2/std.ihx.
Traceback (most recent call last):
File "/usr/local/bin/usrp_sounder.py", line 112, in <module>
main()
File "/usr/local/bin/usrp_sounder.py", line 88, in main
debug=options.debug)
File "/usr/local/lib/python2.5/site-packages/gnuradio/sounder.py", line 179,
in __init__
verbose=self._verbose)
File "/usr/local/lib/python2.5/site-packages/gnuradio/sounder.py", line 56,
in __init__
self._u = usrp.sink_s(fpga_filename='usrp_sounder.rbf')
File "/usr/local/lib/python2.5/site-packages/gnuradio/usrp/usrp_swig.py",
line 2736, in sink_s
return _usrp_swig.sink_s(*args, **kwargs)
RuntimeError: can't open usrp
Is there any problem of the board? what's the problem it is?
Thank you so much in advance.
Regards,
Yan
