SoapyLMS issue? Help identify please

Hello!

I’ve been doing some programming with SoapySDR in C on Windows and I’ve stumbled upon a strange issue - the call to make the SDR device would fail for me exactly every other time. At first I thought I was doing something wrong in the code, so I went into the Pothos distribution, fired up LimeUtil and got the same behaviour.

Here is the --info output:

Here is what I get when I try to --make a device for the first time and then every odd time as well:

Should I build from source and use the latest version? Is this a know issue?

Thanks in advance.

I had too many problems with the SoapySDR C routines - I had to shift everything to the C++ routines to get around the bugs.

On Windows 10 with my LimeSDR-Mini - SoapySDRUtil.exe works perfectly every time.

Have you tried running LimeQuickTest.exe a few times - to see if you get some errors ?

Hello!

LimeQuickTest also fails exactly every other time.

I think I’d start by using the latest version of Lime Suite and then making sure the gateware and firmware are up-to-date also.

You could try running SdrGlut to see if things actually are working ever other time. Almost everything has to be working correctly for it to run correctly. A prebuilt exe is at -

Ok I’ve installed limesuite-git under Arch Linux and can confirm that the problem is not present there. Now I’ll need to find a way to compile it from source on Windows. Thanks!

Alright, I built LimeSuite from the sources under W10, ran LimeUtil --update, the update went well, but the issue still persists. Here is an example of two consecutive LimeQuickTest runs right after I’ve updated, unplugged and reconnected the device:

Also, the LimeSuite seems to have a strict NEQ condition when probing firmware version. That means that if the firmware is newer than the driver expect, it still asks to “update” it. Don’t know if it is an intended behaviour - just something I’ve noticed.
