Segmentation fault on the Raspberry Pi 3 #67

Closed radiojitter closed 7 years ago

radiojitter commented 7 years ago

Thanks for such a interesting SDR framework.i am not sure if we have a blog/forum to share difficulties related OpenWebRX. I tried to find solution to my problem but could not get in net.

My setup : Raspberry Pi 3, OS: RASPBIAN JESSIE WITH PIXEL, Nooelec Nano 2+. My system works well with GQRX with RTL SDR. I have followed http://blog.sdr.hu/2015/06/30/quick-setup-openwebrx.html line by line for my setup and did not update config_webrx.py , after running openwebrx.py , i opened chromium browser and typed http://localhost:8073 The interface is coming nicely but there is no waterfall and no audio. There is no failure message in terminal(LXTerminal in Raspberry Pi, i would provide the complete message dump soon). Please help me to get going. Thanks in advance.

Thank you for your report!

i am not sure if we have a blog/forum to share difficulties related OpenWebRX.

This is the good place.

There is no failure message in terminal

Someone else mentioned a segmentation fault, so you could look for that among the messages.

Yes, please provide the full console output.

radiojitter commented 7 years ago

yes appears segmentation fault. here is complete dump pi@raspberrypi:~ $ cd openwebrx pi@raspberrypi:~/openwebrx $ sudo ./openwebrx.py

Thanks!

This way we would get the source of the segfault:

export LD_PRELOAD=libSegFault.so
python2 openwebrx.py

Could you try it?

radiojitter commented 7 years ago

many thanks Andras, it worked ...:-)

ha7ilm commented 7 years ago

Er... That fixed the segfault? That's not expected.

The expected output is more data in the terminal, including the address of the program counter when the segfault happened, and a stack trace.

Anyway, I'll try that on a Pi myself. What is the version of your kernel? 

uname -a
mprilepok commented 7 years ago

H Andrasi, on Raspberry Pi 3 also the interface is coming nicely but there is no waterfall and no audio. When I execute the commmand export LD_PRELOAD=libSegFault.so firstly and the python2 openwebrx.py, it works.

the kernel is 4.4.50-v7+ #970 , what i saw after openwebrx.py execution, if i close the program by CNTRL+C in terminal, close the client browser connection and try to open config_webrx.py, it does not open and stucks.

Hello Andras, It is the same like I reported on Google Groups. On my Raspi 3 it works too, after starting it with your commands. On the Raspi i didn't see more output after that, but it works. On the NanoPI, where it doesn't work, I have more Output in the Terminal Session.

Thats why I was a little bit confused after it. ;)

Same issue here. Exactly as above. de M1GEO :)

ha7ilm commented 7 years ago

I hope it is fixed by now. I have recently changed the algorithm behind fractional_decimator_ff, but it seems like it corrupts memory. I now reverted to the old algorithm.

Hi How was this resolved ?

ha7ilm commented 6 years ago

AFAIK this was not resolved, the command that I suggested (that contained libSegFault.so) was only for debugging. Unfortunately. when people tried this command, the segfault did not happen again (so that I don't know what causes it).
