gr 3.8, uhd4.0 and rfnoc

Hi, I've been trying to create and use a rfnoc block for n310 within gnuradio 3.8 and uhd4.0. I first tried with pybombs but this doesn't not seem to work very well and there is no default recipe that works. I then moved to manual install from source and got something up using the maint-3.8 and

Oh, I was skipping past that; I was wrongly assuming you were using CentOS 8. Yeah, as Alex said, on CentOS 7, this will be cumbersome. If I was forced to work on CentOS 7, I'd very much consider a podman or docker container or simply a chroot to hold a CentOS 8 (or whatever more modern, really) i

Dear James, CentOS 7 is really really old. I would say that you should ask your customer or project leader to allow you to at least use CentOS 8. You're just going to have a whole set of challenges and difficulties using CentOS 7. Why create more unnecessary work for yourself? Sincerely, Alex-M-H

Regarding your first point, you're right, but I couldn't find the cause yet. At least I couldn't see anything useful in logs like dmesg or GNU Radio's console. Fortunately it doesn't happen very frequently, but it is very annoying when it does. About the second, I'll look into it. My understanding

Hi Fabien, The blocks were built for use with the development version of GNU Radio for a year ago, and as the OOT name states it's very much a work in progress. The blocks function but I haven't updated them for the newest development changes, nor have they been tested for actual 3.8 release

I'd presume there's something going wrong in the communication between your PC and the dongle; maybe a USB packet goes missing, maybe the dongle reboots for some reason, like unstable power supply. It's probably wisest to fix that instead of building a watchdog around it. If you really want to bu

Hi James, our software is called "GNU Radio", not just "GNU" :) Anyway, the relevant python-click-plugins.lwr is most definitely not empty, otherwise your Pybombs wouldn't be calling `yum info python3-click-plugins` (it only knows to do that because of that recipe file). Can you run `yum info py

Hi Fabien, just so you know: We're aware and it's being worked on. If you don't need controlport, then for now, disabling it (cmake -DENABLE_GR_CTRLPORT=Off ...) would be a workaround. Best regards, Marcus On 06.11.20 22:51, Fabien PELLET wrote: > Hello, > > When compiling the actual source tha

Hi Akinyele, GNU Radio companion has an "screen capture" function that allows you to directly save **good** images of your flow graph. Also, your operating system has the same. So, I'll respectfully point out that taking photos with a camera is a complicated and not overly useful method to communi

Hi all, I use GNU Radio with a rtl-sdr dongle, which I tune to some frequency and then leave unattended for some hours. Sometimes, the reception just stops: in my flowgraph, I have some display sinks showing the waveform, and it remains still, like frozen. The GNU Radio interface is not frozen, tho
