Hello,
I am running gnuradio on a Linux x86_64 box, fedora10. I downloaded the
code from the development trunk on 2/26/09. Lately I notice that my
uspr2 has been working intermittently. Sometimes, even running the
example code would give me a segmentation fault error or errors like the
one listed below.
If I turn the uspr2 off and back on then rerun the program, the program
will run again okay.
Has someone seen this behavior before or had any explanation for why it
behaves that way.
Also, is there a command to reboot/reset the uspr2 instead of turning
the power off and on?
Thanks!
./usrp2_fft_copy.py (which is an exact copy of the usrp2_fft.py in
the example)
