Hi,
I installed the latest firmware : "Raw Ethernet with XCVR2450,
V3.3.1git". FPGA images is "u2_rev3-20100603.bin". The OS is
Fedora 13. And the version of gnu-radio is gnuradio-3.3.0.
When I run the command: #usrp2_fft.py -f 2.476G -g 45. The program
can work, but I cannot click any choice box on the screen----
cannot choose the box of "Peak Hold" and others; cannot re-put the
"center freq". The thing likes that the program is dead after it
starts running. I only can force quit it, otherwise it cannot stop
normally. And after I force quit, the following information will
be
shown.
address@hidden ~]# usrp2_fft.py -f 2.476G -g 45
python: Fatal IO error 11 (Resource temporarily
unavailable) on X server :0.0.
Is there anybody can help me? Thanks. And my former problem is
still here that my USRP2 + XCVR2450 only received noise rather
than signal.
Thanks again.
Your "freezing" is very likely due to your machine not being up to
the task of doing FFTs of data at 6.25Msps. Try specifying "-d 40"
on the
usrp2_fft.py command line and see if that improves the usability
of the user-interface.
