SIGSEGV: memory access violation

Has anyone figured this out yet? I cant open any apps. I was able to open CubicSDR the other day but not now QGRX crashes instantly

@ImDroided can't use sudo, not sure it solves it anyway, sudo breaks pulseaudio unless you run it for the whole system, which isn't default.

this issue is: 02-07 20:15:17.086 8009 8047 E CARIBOU_SMI caribou_smi_init@caribou_smi.c:539 couldn't open smi driver file '/dev/smi' (No such file or directory) 02-07 20:15:17.086 8009 8047 E CARIBOULITE Setup cariboulite_init_submodules@cariboulite_setup.c:288 Error setting up smi submodule

Dont know why but fresh install with normal config.txt edit and THIS_MODULE delete CubicSDR now works but gqrx is still a mem access error.

[unixpunk]

@ImDroided i see the same, even though adding those overlays gives me /dev/shm, so i dont see that file doesn't exist error, but the software is still causing the cairboulite driver to access invalid memory. wonder if we need a new udev rule or something, like the mem access is getting blocked because its done differently than CubicSDR (which still works fine).

[ImDroided]

So after letting CubicSDR run overnight and all day on a FM radio station I closed CubisSDR and could not open it again until after a reboot. Same mem access error.

[great9]

on my rpi 3b with 512 mb ram it spins up 2 reader threads an 2 writer threads with immediate 400% Load on SDRPlusPlus. This makes all communication choppy, with or without compression enabled. When I kill the smi threads an rmmod the smi_stream_dev , it crashes with mem error and it's not possible to use it again until reboot.

@ImDroided when yours works, it at least works.

[unixpunk]

@great9 pi 3b is only good for SoapyRemote / SoapySDRServer scenarios, it can't do all that extra work processing the fft and demodulating audio, etc - BUT if you just run sudo SoapySDRServer --bind and then use sdrpp or cubicsdr, etc on a more capable machine, the audio will work fine. Side note - use TCP, not UDP when selecting the remote Caribou sdr in the chosen app.

If you want to see the fft and hear non-choppy audio, you'll need a pi 4.
