Re: Problem with my USrp

[Fabian Schwartau]

Hi Bass(e),
can you tell a bit more about what you are doing?
Just starting the USRP, setting it up and stream?
I once had a (at least) similar problem. I can't remember right now
exactly what it was, I can just remember that I did something a bit
ususual. If I remember correctly I was initializing timed measurements
one after another and the USRP crashed after doing this 256 times, also
resulting in a "no response packet". A hard restart of the USRPs then
fixed the problem for the next 256 requests.
I "fixed" the problem by switching to an older version of the library.
It was 3.10.2 that worked for me.
Nevertheless, your message just says that the USRP did not respond for
some reason. Is it working for a short time after the error without
restarting the USRP?

Best regards,
Fabian
