I meet a problem when I run the gsm-tovid.  
Firstly, I enter the /airprobe/gsm-tvoid/src  
typed : ./gsm\_scan.py -p d -c 39 > scan\_results  
  
a error arising:  
root@ubuntu:/home/my\_project/usrp/airprobe/gsm-tvoid/src/python\# ./gsm\_scan.py -p d -c 5  > scan\_results  
% offset =  0.0 clock =  64000000.0  
fusb\_block\_size = 4096  
fusb\_nblocks    = 16  
Traceback (most recent call last):  
  File "./gsm\_scan.py", line 734, in <module>  
    main()  
  File "./gsm\_scan.py", line 728, in main  
    app = stdgui2.stdapp(app\_flow\_graph, "GSM Scanner", nstatus=1)  
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 36, in \_\_init\_\_  
    wx.App.\_\_init\_\_ (self, redirect=False)  
  File "/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/\_core.py", line 7978, in \_\_init\_\_  
    self.\_BootstrapApp()  
  File "/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode/wx/\_core.py", line 7552, in \_BootstrapApp  
    return \_core\_.PyApp\_\_BootstrapApp(\*args, \*\*kwargs)  
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 39, in OnInit  
    frame = stdframe (self.top\_block\_maker, self.title, self.\_nstatus)  
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 60, in \_\_init\_\_  
    self.panel = stdpanel (self, self, top\_block\_maker)  
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/stdgui2.py", line 81, in \_\_init\_\_  
    self.top\_block = top\_block\_maker (frame, self, vbox, sys.argv)  
  File "./gsm\_scan.py", line 174, in \_\_init\_\_  
    self.setup\_flowgraph()     
  File "./gsm\_scan.py", line 554, in setup\_flowgraph  
    self.setup\_usrp()  
  File "./gsm\_scan.py", line 366, in setup\_usrp  
    options.rx\_subdev\_spec = pick\_subdevice(self.ursp)  
  File "./gsm\_scan.py", line 88, in pick\_subdevice  
    if u.db\[0\]\[0\].dbid() >= 0:  
TypeError: 'instancemethod' object is not subscriptable  
  
So I look the error messages and open the gsm\_scan.py. I use ctrl + F to locate the pick\_subdevice function. I think u.db\[0\]\[0\].dbid() is not matched for new Gnuradio Version. Because the Gnuradio is updated to 3.4.1 now. I open other Gnuradio example code to compare this function and find it now uses u.db(0,0).dbid() not u.db\[0\]\[0\].dbid().  
   
def pick\_subdevice(u):  
    """  
    The user didn't specify a subdevice on the command line.  
    If there's a daughterboard on A, select A.  
    If there's a daughterboard on B, select B.  
    Otherwise, select A.  
    """  
    if u.db(0, 0).dbid() >= 0:       \# dbid is < 0 if there's no d'board or a problem  
        return (0, 0)  
    if u.db(0, 0).dbid() >= 0:  
        return (1, 0)  
    return (0, 0)  
  
![airprobe: gsm-tvoid : gsm\_scan.py problem part1][airprobe_gsm-tvoid_gsm_scan.py_problem_part1]  
  
![airprobe: gsm-tvoid : gsm\_scan.py problem part1][airprobe_gsm-tvoid_gsm_scan.py_problem_part1 1]  
  
  
  
  
using new code fix it right and go on.  
It can run but another problem arises.  
  
  
root@ubuntu:/home/my\_project/usrp/airprobe/gsm-tvoid/src/python\# ./gsm\_scan.py -p d -c 5  > scan\_results  
% offset =  0.0 clock =  64000000.0  
fusb\_block\_size = 4096  
fusb\_nblocks    = 16  
>>> gr\_fir\_ccc: using SSE  
>>> gr\_fir\_ccf: using SSE  
Segmentation fault  
  
  
This error is very difficult. Oops!! What the hell is going on?  
Now I try my best to find the answer.
