[Discuss-gnuradio] get fatal IO error 11 when running usrp2_fft.py (USRP2 + XCVR2450)

[XIAN PAN]

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.
