Re: [USRP-users] N310 timeout before streaming complete

Hi Rob, I just wanted to post an update. We have found the root cause of the issue. The primary cause is that the 2 channels are not stopping at the same time and the code is only looking at the EOB flag for channel 0. When any other channel stops before channel 0, the code hangs waiting for da

1 Gbe Ethernet can't handle that much data. Most 1 Gbe class NIC controllers prevent you from setting the MTU over 1500 anyway. I would be surprised if the GUI settings in network manager actually went through. If you type 'ifconfig' in a command console the host NIC is probably still running at 15

I reproduced the same issue (except I completely uninstalled GR, UHD, gr-ettus, etc. before doing rm -rf rfnoc then installed rfnoc from scratch) then checked out 'eb5eed' in uhd-fpga which fixed the FPGA compatibility number issue but there seems to be an underlying problem with that. I can't use

All, I'm having an odd issue that is occurring on an E312. I've tried this same code on different e310's and it works fine. Hadn't used the E312 in a while and now when i try to run gnuradio code or even just run uhd_usrp_probe I get errors like below. Any ideas how to fix this? Thanks! Jack r

OK thanks, Ale; maybe you did say; now we really do know ;) Related: What version of UHD are you using? The UHD version does make a difference, as some issues with the B2XY series have been fixed recently that were introduced after the 3.9 LTS release. - MLD On Mon, Oct 15, 2018, at 8:43 AM, Merc

Here's the rx streamer init. It is in the main function after initializing the usrp device. This happens with both sc8 and sc16 wire format with float32 cpu format. uhd::stream_args_t rx_stream_args("fc32",wire); //complex floats rx_stream_args.args["spp"] = str( boost::format( "%u" ) % spb );
