Hi All,
When you use an USRP2 for capturing and you call
u2->stop_rx_streaming()
and later
u2->start_rx_streaming(0)
You always get a single overrun.
-a single 'S' is output on the console
-u2->rx_overruns() returns 1 (in stead of 0)
I am developing a usrp2 application which does not permit any overrun
conditions, so this needed fixing.
It turns out that the expected sequence number of received samples is
not reset when stopping the stream.
This single line patch fixes this.
Best Regards,
Martin
