S912 armlogic has cortex-A53 cores which are 64-bit as is your OS.
You have already installed two fundamental 32-bit libraries (libc6:armhf and libstdc++6:armhf)
Do you also need to install additional 32-bit library for spyserver, I honestly don't know!
I'd check on the easy ones that were statically linked at build time first:
$ ldd spyserver
And if installing any missing 32-bit libraries did not solve the problem, then I'd see if there was any issue with any missing 32-bit dynamically loaded resources (e.g. libairspyhf.so, librtlsdr.so, libairspy.so )
You can use a debug tool like strace to find out which files in what directories the program is trying to access (there will be many misses as it searches through the entire library path, you learn what is important and what is irrelevant by using debug tools often enough).
$ strace -f ./spyserver
(or a quick check for library files only "strace -f ./spyserver 2>&1 | grep -i lib" or files that were attempted to be opened "strace -f ./spyserver 2>&1 | grep open" )
If any required library files were missing, I'd look for the package name that owns the missing library file.
e.g
$ sudo dpkg-query -S librtlsdr.so
And install the 32-bit version, e.g.
sudo apt-get install librtlsdr0:armhf
And then rinse and repeat for anything else that is missing. Oh and never expect any program to have any chance of work correctly when it is being debugging with strace, just run the program directly.
That would be how I would approach your problem.

I still have the same issue,spyserver is not "grabbing" the rtl dongle as it should. I  checked spyserver.config and all seems well enough, tried defaults, tried device as RTL-SDR and numerous sample rates within the accepted perameters for RTL 2k, 1k etc..
Tried with a friends airspy AirspyOne device attached to the unit and default spyserver.config, same results unfortunately.
Any more suggestions much welcomed.

There are several standard extensions to the .wav format which allow essentially
unlimited recording. Why not use one or more of them?

Hello Patrick,

you can use Linrad with your Airspy and record unlimited
file sizes. (Your hard disk would be the limit.)

You can locate regions of interest and write small files
that can be converted to standard .wav files if you want
to process on another SDR software.

Linrad uses a 64 bit file pointer while standard for .wav
files is a 32 bit pointer.

Hi there,

A single recorded file (full 768 kHz BW) seems to be limited to 2 Go ; this
means the recording won't last more than about 12 minutes.

Is it possible to record a single file during 30 minutes or 1h or even more
? (still at 768 kHz BW of course).

Thanks
Pat

Hi Gary,

You need to use an Ext-IO file which will allow the HF+ to work with HDSDR.  You can download it here:

montefusco.com/airspy/

Note there is one for the regular Airspy and one for the HF+.  Download it and copy it into the folder on your computer where HDSDR resides.

Hi, Looking for help (advice) for getting AirSpy HF+ to run with HDSDR.

I can run the KC9QLE SDR on HDSDR and the Airspy runs perfectly on SDR# (as does the KC9QLE SDR).

But HDSDR just won't recognise AirSpy.

All relevant advice gratefully received. Footnote - all on the same computer.
