Hello Maria, the reason I most often encountered for this is that in the middle of operation, Ubuntu decided to reconfigure the network interface. Make sure you set the network interface to a valid address from the 19.168.10.XXX network (except .2), and configure the network manager for "static" addressing.
also, for some reason, your USRP's subnet mask as reported by uhd_usrp_probe seems wrong; it should be something like 255.255.255.0, not 255.255.255.255. By the way, what is your network card? (you can find out by doing "lspci|grep -i ether", usually) Best regards, Marcus On 02/22/2016 10:36 PM, Maria Christopoulou wrote: > Hello, > > I have the following system configuration: > > Ubuntu 14.04, 64-bit, 3.17.0-lowlatency > Gnuradio v3.7.8 > and a USRP N2930, with UHD_003.009 version installed. > > The script uhd_find_devices works properly and the output of > uhd_usrp_probe is the following: > > https://drive.google.com/file/d/0B9y0kqNk6AFgNnpFLWcwZ2E4WDQ/view?usp=sharing > > > When I execute the uhd_fft.grc flowgraph, the program runs for a few > seconds but suddenly freezes, showing the following output in the > terminal: > > https://drive.google.com/file/d/0B9y0kqNk6AFgY2NpdW0yS2sxMDA/view?usp=sharing > > Could you please give me some guidelines to solve this issue? > > > Best regards, > Maria Christopoulou > > > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
