Hello all,
I've had trouble making a 4 channel USRP samples at 1Ms/s write to file at 500 kS/s with ubuntu 12.04 and libuhd. I am getting several overruns and I had tried adjusting some of the parameters using usrd_probe_devices but with no success. I have a laptop with a duo core centrino processor which should be enough.
I've made
this 4 channel work successfully with the same exact laptop and with ubuntu 10.04 and the older version of gnuradio that uses libusrp. I get no underruns at all even for an entire hour of writing to file.
Has anyone else experienced performance differences between libusrp and libuhd? I just want to make sure it isn't a configuration problem or something I'm doing wrong causing the overruns. If its likely an issue with libuhd, I guess I will just keep a backup of ubuntu 10.04 and gnuradio libusrp version installation files and leave my dual boot setup intact.
Thank you very much, - Tom
