By the way, I just changed my "flush" sequence to use the end_of_burst flag (when streaming with STREAM_MODE_START_CONTINUOUS), but the issue still occurs. Attached are the modified source code and the resulting console log. The new flush sequence is shown below. Again, this is not an issue for

Thanks Michael, Are you saying that when running with STREAM_MODE_START_CONTINUOUS, I can expect a "md.end_of_burst==true" shortly after issuing the STREAM_MODE_STOP_CONTINUOUS? If so, that seems like a much better method for flushing all of the samples following the stop command. In any event,

Hi Rob, Excellent feedback as always. Thank you. We will look into the RX burst behavior using STREAM_MODE_START_CONTINUOUS, but it may take some time. The flush routine should have a timeout for the recv() call and be looking for md.end_of_burst to exit, but I'm sure there is more to the issue

Martin, Michael, Sorry for the long delay in responding. I hadn't been monitoring the user's list this past week and the replies you sent did not come directly to my inbox. In any event, I compiled the latest MPM and it seems to work fine. Thank you. Now, to the secondary issue I mentioned in

Rob, we pushed a fix for the TX spectrum issue to UHD-3.13 and master. -- M On 08/15/2018 05:24 PM, Michael West wrote: > Hi Rob, > > We have reproduced the TX corruption issue and we are troubleshooting.  > In the meantime, you can try using the head of UHD-3.13 with the > force_reinit=1 as

Hi Rob, We have reproduced the TX corruption issue and we are troubleshooting. In the meantime, you can try using the head of UHD-3.13 with the force_reinit=1 as Martin suggested. If that doesn't do the trick, we did find a combination that seems to work: UHD and FPGA image from the head of

I can't comment on the MPM or images but we had N310 streaming timeout issues that were recently fixed. Upgrading from UHD 13 to 13.0.0.1 fixed all our (seemingly randomly occurring) streaming issues. On Thu, Aug 9, 2018 at 2:31 PM, Rob Kossler via USRP-users < usrp-users@lists.ettus.com> wrote:
