Hello,
just realized that I forgot to insert the part after "bt"
last time...
So once again:
This is what GDB says:

I definitely have the latest GNURadio release installed.
uhd_find_devices and uhd_usrp-probe both work fine.

Hello list,
I tried to launch the "uhd_fft.py" script with the
following command line:
"uhd_fft.py -a type=usrp2 -f 935M -s 2M"
My problem is that my terminal always returns this
output:
linux; GNU C++ version 4.5.2; Boost_104200;
UHD_003.001.000-a7927ae
-- Opening a USRP2/N-Series device...

Segmentation fault
Does uhd_usrp_probe work? If so, is there a particular
line in
uhd_fft.py that causes the seg fault? Have you debugged
w/ gdb?
In any case, I recommend upgrading to the latest
release, then see if
there is still a problem.
-Josh
I am using Linux Ubuntu 11.10, 32bit, Intel® Core™2 Duo
CPU P8600 @
2.40GHz × 2, USRP N210 with WBX.
I also use ClockTamer as reference for the internal XO
and 2 normal GSM
900 antennas.
I would really appreciate if someone has an idea on what
I am doing
wrong here.
Thanks in advance!
Sebastian
