Illegal instruction

[Nixellion]

I keep getting this error: "Illegal instruction", and nothing else while trying to run any of the examples from here: https://github.com/respeaker/respeaker_for_raspberrypi

I narrowed it down to this command:
ns = NS(rate=src.rate, channels=1)

I've installed provided raspbian image with everything preinstalled.

Anything?

Are you using Pi Zero?
I should add a note that these images only support Pi 2/3. Pi Zero uses ARM11, while Pi 2/3 use ARM Cortex A.

I see. Everything else works fine though. I suppose it's more about voice engine than it is about the image itself?

I'll see if I can make porcupine work instead of snowboy. Thanks.

It's a issue of pre-compiled python packages. The NS element is based on webrtc-audio-processing python library. For Pi Zero, we need to re-compile the package:

sudo pip install --force-reinstall  webrtc-audio-processing

It's the same for snowboy. Compile and re-install it. It should work.
