Upgrade from DVSDK 3.0 to 4.01 and have problems in ALSA audio

Elias Kokkinis

I am developing some audio/speech applications on OMAP3530EVM (by Mistral) and until recently I was using the DVSDK v3.0.

However, since most of development will be going on in ARM and we want to leverage the DSP power in a simple way we switched to DVSDK v4.01 in order to use the C6Accel framework.

I have tried to run the executables that I built with the previous SDK in the board under the filesystem of version 4 and nothing seems to work in terms of audio. Even the most simple testing application which does a simple audio loopback via ALSA does not work as expected.

Has anyone encountered anything similar when upgrading? Do you have any tips?

Thanks!
