Can someone help me install pyaudio/portaudio on the imx233 (Maxi) board? I'm using openWRT. I don't have much embedded linux experience and none at building a module from source. Any help would be appreciated.
The easiest way to build some software for OpenWRT is to just write a custom package Makefile.
(Once your package works well, submitting it for inclusion into OpenWRT is appreciated.)
To get started, have a look at some simliar OpenWRT package - ie some other python
module in your case. Reading docs/openwrt.pdf maybe also will explain some details.
Other than that you will need to ask more specific questions.
