Hi Andrew, The fix is on the master branch (commit 8922095 ). It is being included in the next set of commits on the maint branch that should be available in the next few days. Regards, Michael On Wed, May 2,

Re: [USRP-users] Core dump with UHD_3.11, X310, and LFTX

Thanks Michael. Do you know if I were to install rfnoc under a different prefix would the UHD version be able to be switched between the prefixes? I'm using an older rfnoc build compatible with Vivado 2015.4 and hesitant to install the latest build and checkout that new fix if it it will overwrite

[USRP-users] how to know the number of losted samples when overflow occurs ?

Hi, I remark that the "time_spec" passed to the "recv" method of an rx_streamer is not in exact relation with the length of the received vectors. For example, when receiving buffers of length 16384 at Fs=362319 Hz, the buffer length should be equal to (16384+1)/362319=0.0452225 seconds, while

Re: [USRP-users] USRP Underruns "UUUUU"

Hello Yeo Jin, First, find the maximum effective sampling rate that you can achieve with your computer. Connect a constant source to a USRP sink (for USRP sink underruns), or connect a USRP source to a null sink (for USRP source overruns) and run the flow graph. Try different sampling rates

[USRP-users] B200mini sc12 wire format broken?

Hi, I switched from UHD release 3.10.2.0 to the latest release 3.11.0.0 and recognized in my Gnuradio application, that UHD gives errors when using the sc12 wire format. However, only when I use the USRP in receive mode. In transmit mode, the sc12 format works. The sc8 and sc16 wire format

[USRP-users] USRP Underruns "UUUUU"

Hi all, I am getting underruns and overruns when trying to run the UHD programs, both GNU radio and C++. The maximum my computer can handle is 4MHz sampling rate before seeing "U". I've searched online and most people say, change a new computer into quad core etc. Are there any other ways

Re: [USRP-users] USRP Underruns "UUUUU"

Hi Yeo, Just in case, confirm that you have connected the board to a USB3 port. Afterwards, confirm that the program logs says that "it is operating with USB3 speeds". Hope it helps. Alfredo Gardel El 04/05/2018 a las 11:29, Yeo Jin Kuang Alvin (IA) via USRP-users escribió: Hi all, I am
