Subject: | [Discuss-gnuradio] uspr2 working intermittently/segmentation fault |
Date: | Wed, 01 Apr 2009 15:00:57 -0600 |
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) usrp2:
