The strange thing is that the errors come after the RSP has been discovered and it's properties reported so I'm struggling to see that it's directly related to that - although I take the point that it doesn't do it with the RTL device.

I have just looked and SoapySDRPlay is now using deprecated functions in the new SoapySDR - bit of a long shot if that's involved?

Have you tried building 0.4 versions of SoapySDRPlay and SoapySDR to check?

Best regards,

I have done some more test and now is clearly a SoapySDR problem.

Removed all SoapySDR* libraries and CubicSDR
New and fresh git clone for SoapySDR, SoapySDRPlay and SoapyRTLSDR
Compile and install without problem.

SoapySDRUtil --find

show correctly RTLSDR and SDRPlay devices

SoapySDRUtil --info

show factory for null, rtlsdr and sdrplay

SoapySDRUtil --probe and also --probe=sdrplay

show only RTLSDR device (--probe show 2 times same device)

Code: Select all

spin@franco:~/Scaricati/CubicSDR/SoapyRTLSDR/build$ SoapySDRUtil --probe

and running Python test program from SoapySDR wiki, as per my previous message, crash Ubuntu 16.04 at stream level.

So, not a Cubic problem but a SoapySDRPlay problem with new and old API (1.9 1.94 and 1.95)
Same source, compiled on Ubuntu 14.04 64 bit work without any problem with API 1.9.

How can I downgrade to 0.4 version of SoapySDR*?

But it if is an SoapySDR problem, why does it work for me, but only on USB 3.0 ports??

My setup is basically the same as Franco's, everything build from source with all sources from their respective git repos.

Ubuntu 16.04 is a fresh install, not an upgrade.

I suppose a compatibility problem between libusb, Soapy and some other library.

Gqrx and gr-osmosdr run OK on 16.04 with new API and using SDRPlay device, not SoapySDR device.
So API library is correct, if used from gr-osmosdr. I don't know differences in library usage between gr-osmosdr and Soapy*

We need help from support, with some version of API or SoapySDRPlay modified for testing.

It does sound like a libusb problem.

Try building/installing the latest libusb...

https://sourceforge.net/projects/libusb ... sb-1.0.20/

If that doesn't work I'll modify SoapySDRPlay to add debug info.

As I mentioned before, SoapySDRPlay is now using deprecated functions because of 0.5 SoapySDR.

You should be able to build 0.4 from the SoapySDR github source revision history.

Maybe try that before libusb

Aye, I built it from the latest github pull from today. Unfortunately the issue still exists - I drilled down with some tests -on both USB3 and USB2 ports and these are the results - using GQRX (latest GitHub) and others:

|| Rate | Decimation | Result ||
| 100000 | None | OK |
| 100000 | 4 | OK |
| 10000000 | None | Kernel panic (actually setting this mode causes it |
| 12000000 | 16 | Kernel panic after roughly one second of activating capture |

I also tried max settings on my RTL dongle (no decimation) and it held up fine.

It looks like there's *something* in the driver that causes a kernel panic as soon as these are set from whichever app / tool.

Hope this helps!

Couple of things to note about that. We don't do decimation in the same way now. I really need to find some time to update the SoapySDRPlay module.

Max sample rate should be 10MHz, don't use any higher than that.

I don't know how a sample rate of 100kHz can be derived using a decimation factor of 4 - min sample rate is 2MHz

Also a quick look at the code I see that decimation is only applied in Low IF mode - have you tried Zero IF mode without decimation? I've never really understood why Low IF mode seems to be the default in that module.

Best regards,

Some inquiry on libusb in Ubuntu 14.04 and in Ubuntu 16.04

On Ubuntu 14.04 both API (1.8.4) and SoapySDRPlay library require libusb-1.0-0 and
on this system libusb is at version 1.0.17-1

On Ubuntu 16.04 both API (1.95.1) and SoapySDRPlay library require libusb-1.0-0 and
on this system libusb is at version 1.0.20-1

So the only difference is in libusb version. Can be a change in libusb from 1.0.17 to 1.0.20?
But libusb is used by API and by SoapySDRPlay (why?) and API is used by gr-osmosdr

Gqrx is working with gr-osmosdr so API and API usage of libusb is correct but SopaySDRPlay usage of libusb is incorrect?

Is this a possibility?
Crash are all at stream level, when SoapySDR activate stream
