I've had a usrp version 2 running successfully for several months but that
changed abruptly a couple of days ago and I can't get it operating again. I'm
running from version 2.5 tarballs and Debian Sarge on an i386 system.
After stopping and restarting an application I get the the following message
that looks like the application cannot open the usb interface to usrp:
self.src = usrp.source_c (0, self.usrp_decim, 1, 0xf0f0f0f2, 0)
File "/usr/local/lib/python2.3/site-packages/gnuradio/usrp.py", line 65,
in source_c
return ((usrp0.source_c, usrp1.source_c)[look_for_usrp(which)])(which,
*args, **kwargs)
File "/usr/local/lib/python2.3/site-packages/gnuradio/usrp1.py", line
1168, in source_c
return _usrp1.source_c(*args)
RuntimeError: std::runtime_error
Running usrper load_standard_bits gives this output:
debian:/home/ward/usrp-0.8/host/apps# usrper load_standard_bits
usrper: found unconfigured usrp; needs firmware.
usrp_open_interface: usb_claim_interface: failed conf 0
could not set config 1: Invalid argument
open_nth_cmd_interface: open_cmd_interface failed
usrper: failed
Why would I start getting the "Invalid argument" between application runs? Any
help regarding what to look for would be appreciated.
Thanks,
Ward
