[Discuss-gnuradio] Tuning problem - usrp_fft.py -> segmentation fault

[Fabian Uehlin]

Hello!

I have a Gentoo Linux system with KDE and the current svn version of  
GNURadio and OpenBTS (revision 10370).
Because tuning of my two daugtherboards (RFX-1800, USRP1) failed with  
OpenBTS, an user give me the hint to run usrp_fft.py.

So I run
usrp_fft.py -R A -f 1724.4e6 or
usrp_fft.py -R B -f 1724.4e6

It returns
"Segmentation fault"
nothing more.

Running
usrp_siggen.py -T A -f 1819.4e6 or
usrp_siggen.py -T B -f 1819.4e6
returns
"Using TX d'board A: Flex 1800 Tx MIMO B" or
"Using TX d'board B: Flex 1800 Tx MIMO B"
nothing more.

The main problem is, that OpenBTS occurs an error, that the  
daughterboard could not tune to the
desired frequency. So I tried to fix it, but without success.
But now it seems, there is a general problem with tuning my USRP/ 
daughterboards?!

What could be the problem? Does anyone have an idea?

Thanks & Regards
        -Fabian-
