[Discuss-gnuradio] USRP Underruns "UUUUU"

[Edwin Li]

Hi,

 

There are several things you can try:

 

1. Split the USRP sink and source to two separate flow graphs.
2. 20M sampling rate is very high. Make sure your computer can handle this rate. If not sure, just reduce the rate.
3. If any of the above does not work, you may try to run “volk_profile”. It is in “prefix/bin/”

 

Regards,

Edwin
