Has anyone had issues with the E320 GPS locking or staying locked? I have a LabSat GNSS simulator that I am reliably able to get a E310, X310, and even a N310 to lock to however the E320 I just got will occasionally lock and then fall out almost immediately. I used mender to up it to 3.15LTS and

ges on the FPGA side. So, moving to 'master' may be a pretty big undertaking. * You should not use rfnoc dev branch as this has been dormant for a long time (a couple of years) Rob On Tue, Mar 17, 2020 at 8:59 PM Long, Jeffrey P. via USRP-users mailto:usrp-users@lists.ettus.com>

[USRP-users] RFNOC uhd api vs traditional

2020-03-17 Thread Long, Jeffrey P. via USRP-users
I have been working on applications to control a N310 directly using the uhd api. As I work with the code I am noticing there is a difference in the way you bring up a usrp in what I will call the traditional (legacy) uhd::multi_usrp::make() approach vs the newer uhd::device3::make approach whic

Maybe this is a stupid question but I can’t find anything in google land. Can we use the jtag port on the N310 to chipscope? I have successfully built and run images and so I created a build with some debug via a single ILA. It looks good and I loaded it using uhd_image_loader. Usrp probe it and

you're doing it all right. What's the size of your input buffer on your custom DUC? Also, can you post a full log of the streamer setup? -- M On 01/09/2018 08:41 AM, Long, Jeffrey P. via USRP-users wrote: > Looking for some advice and help on RFNOC.. > >   > > I am crea

Looking for some advice and help on RFNOC I am creating a custom RFNOC block that will roughly do what the noc_block_duc does but instead uses a fractional polyphase interpolator. I believe I have everything working correctly in terms of the tlast and EOB and for single timed bursts it seem
