Re: [USRP-users] twinrx consistent phase offset

Hi Marcus I've given this a try, unfortunately I'm running into a problem with that. I've always gotten strange crashes with UHD 3.15 with this codebase (probably my fault, but I'm not sure why yet). I can collect around ~200 datapoints-ish (about 20-ish retunes of the receiver), before it crashes

Rob, I am using UHD 3.15.  Thanks for pointing me to the section in the ...builder.py script.  I noticed that it is finding the source files correctly and generating the include file "Makefile.OOT.inc".  However, the include file was not part of "Makefile.e31x.inc".  I did a grep search for M

Re: [USRP-users] meta-ettus-v4.0.0.0 segfault

Adding some more data points. 1) I've been trying to rebuild meta-ettus-v4 with debug enabled but am hitting an issue with image size and can't seem to get past that. It says I should increase `MENDER_STORAGE_TOTAL_SIZE_MB` if the actual size is larger but increasing this seems to have no effect.

Re: [USRP-users] RFNoC loopback without radio cores in C++ (UHD-3.15.LTS)

Hi Rob, Thanks again for your response. Enabling UHD logging didn't give much more information about my "No upstream blocks." message or about anything that might give any clues to make the program work. I'll attach my .cpp in this mail in case anyone sees anything off with it (as a quick reminde

Re: [USRP-users] RFNOC - noc_block_gain not found

Mike, Are you using UHD 3.15? If so, I suspect that UHD itself is the issue - particularly the uhd_image_builder.py script. My own experience is that starting around 3.15, some things changed in the uhd_image_builder.py script and caused issues in finding OOT files. Take a look in the python crea

Hi, I've been going through AN-823 (Getting started with RFNoC Development) and have successfully gotten through the point of simulating the gain test bench with positive results. I'm attempting to build the FPGA now with the new OOT module. I've successfully built with only pre-existing mod

Hi, I am working on deploying software that uses the USRP N210 in a centos7 docker container on windows. However we are seeing poor networking performance, even with iperf. Does anyone have any experience with adjusting the networking configuration options for the container and windows so that
