Linux UHD/USRP Support

[erichahn]

CubicSDR seriously needs UHD support in linux. The UHD drivers are already supported for linux, when will cubicsdr accept them?

[cjcliffe]

@erichahn should be bundled with the AppImage and Flatpak 0.2.0 releases -- possibly just throwing an error?

[erichahn]

The release page https://github.com/cjcliffe/CubicSDR/releases/tag/0.2.0 says that UHD is only supported in Windows and OSX though. After running a USRP with GQRX in linux, closing, and launching Cubic 0.2.0 nothing is discovered. Secondly, adding a device manually has no option for a USRP/UHD device.

[erichahn]

This probably should be a separate issue, but I also can't get a USRP working with Cubic in Windows 10 either. UHD drivers are installed.

[cjcliffe]

Ah yes getting ahead of myself -- I forgot there's still some issues with bundling UHD in Linux; but building the module yourself should work with the modpath parameter (available via --help):

--modpath=<str>   Load modules from suppplied path, i.e. '-m ~/SoapyMods/'

As for Windows/OSX I can't recall if it's ever been confirmed working with my builds and I don't have hardware to test with -- but I was able to build and bundle the module and it initializes in the log; however that might still be dependent on my build systems somehow.

You may have more luck with CubicSDR builds included with Pothosware for the moment: https://github.com/pothosware/pothos/wiki/Downloads

[erichahn]

Hopefully this gets figured out soon. I'd love to see people starting to use and develop cubic more. The UHD/USRP users out there would love to build plugins and support this projects.

[erichahn]

I'm getting it to detect the USRP now, but getting the following errors.

[ERROR] recv packet demuxer unexpected sid 0xfdf41307
O[ERROR] The receive packet handler caught a value exception.
ValueError: bad vrt header or packet fragment

Secondly, the sample rate options only go up to 16 MHz, and no text is displayed for the device selection.

[erichahn]

UPDATE: Got it working, but this is just random guessing at settings.

Still cannot set sample rate properly.

Would love to have the option of having longer scroll back periods or something for looking at quick signals.

Build CubicSDR, liquid-dsp and SoapySDR from head.

I see the same problem that Eric sees -- no text for the device name under local.

If I select the device and hit start, CubicSDR crashes:

I can do a RelWithDebInfo build, if more symbols are needed.

Will investigate on my own, but thought I'd get the bug report in first.

guys, I have a B205 working under gnuradio, but im not how to point cubicsdr to the driver/module. Do i have to build it for cubic specifically?

erichahn ,
could you please provide the command line string you used to get your usrp working?

cjcliffe ... "building the module yourself should work with the modpath parameter (available via --help): --modpath= Load modules from suppplied path, i.e. '-m ~/SoapyMods/'"

could you expand on what this means exactly?

thanks guys,

thanks

[erichahn]

I've been trying to get this to work again recently and have been having trouble with versions 2.4 and 2.5. Using pybombs now for easier installs/setups but never able to get the uhd modules to work properly even when using the -m option pointing to uhd modules.

Nothing pops up in the device list as it did in the screenshots above.

[erichahn]

Here are some screenshots of what I've tried. Nothing has made it work or even detect.

[erichahn]

It's never able to find any "factories" Error with Available factories...No factories found! Even when it lists libraries that to me might work, but I have no idea.

[Dantali0n]

The install root of SoapySDR looks wrong being .//////// not sure if that's an artifact of it being an AppImage or an actual problem.

[erichahn]

Any updates?

[erichahn]

Still hoping that this could be resolved!
