couldn't create queue

Noia

Dear forum!
I'm trying to compile and run a pd patch using the heavy library. It does compile and run with default block size, but has issues with dropped blocks. When I try to set a larger block size with the -c "-p 128" flag to the build_pd_hvcc.sh script I get the following:

couldn't create queue
Error: unable to initialise BelaContextFifo
Error: unable to initialise audio

Do you know its cause and what I could do to prevent or work around it?

What hardware and core code revision are you running this with? Is it possible that you have another instance of the program running ? Try rebooting the board to be sure.

giuliomoro I'm running a Bela Mini with multichannel expander, image v0.3.8h and a BelaPlatform pulled from the dev branch in the beginning of June. Is there anything I should consider updating?

giuliomoro

Try updating to the latest dev again, I won't have time to try it out till tomorrow at the earliest.

Tested with an uptodate dev, after fixing an unrelated bug that had sneaked into the code ( std:st ring ) I'm back at the same place:

Running /root/Bela/projects/PD-latt241114/PD-latt241114 -p 64
couldn't create queue
Error: unable to initialise BelaContextFifo
Error: unable to initialise audio
Makefile:615: recipe for target 'run' failed

I can't reproduce on the same hardware and revision... Can you post your full Bela project (including the hvcc-generated file) somewhere ?

Noia

It will not stay there forever, but for the time being it can be found at:

https://github.com/LeoCorreiaDeVerdier/Typer/blob/master/Typer.zip

(as can the code generating it).

Thanks a lot for your effort!

giuliomoro

And can you confirm how you are running it?

Noia

./build_pd_hvcc.sh ~/Dropbox/Typer/patchar/Typer -c "-p 64"

giuliomoro

Please show the result of running this on the board:

grep detectlibraries /root/Bela/Makefile.libraries

Noia

it says

$(AT) resources/tools/detectlibraries.sh --library $(LIBRARY)

giuliomoro

Right, that indicates you are not actually running the latest dev. Can you try updating again please?

Noia

I've tried updating twice with the same results, downloaded from https://github.com/BelaPlatform/Bela/tree/dev . Do you know anywhere old files could linger that I should wipe?

giuliomoro

I guess something goes wrong during the update process. Can you show the content of /root/update.log ?

Noia

Yes, now, trying to update the board I ran into some errors:

Try the latest dev branch, that should work?

Noia

giuliomoro Thanks a lot! Now it works! Board updated clean and hvcc build script runs with different blocksizes.
(unfortunately it didn't prevent the underruns, even with blocksize set to 1024, so I must go untangle my own code elsewhere)
