Any pointers ? I tried resetting usb port with a custom script but that dint help. Rest other scripts are working fine. bencmark_tx, benchmark_rx everything working. Only uhd_fft is painful. Strange thing is that when I made a grc for viewing fft with QT, it is working well without any errors. -- View this message in context: http://gnuradio.4.n7.nabble.com/Bad-address-tp43138.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
