UHD examples Segmentation Fault

[rafael.acurcio]

Hi all,

I'm having some problems trying to use the UHD examples.

Some of them I can use. However some of them give me a Segmentation Fault

==========================================================

rafael@rafael-Inspiron-7537:/usr/lib/uhd/examples$ ./tx_bursts --secs 5 --ampl 0.5 --freq 50e6

The same problem for examples like:
rx_timed_samples, test_timed_commands, tx_bursts, and others

I'm using:

-Ubuntu 14.04

-USRP n210

Hi Rafael,

While you may find some other UHD users in these forums who can help the best bet is probably to send your question to support@ettus.com since they are much more experienced in UHD troubleshooting.

Best Regards,
