Hi,
We are building the board based on beaglebone black and have a TLV320AIC3206 codec on the board, I would like to know if Sitara Linux SDK supports TLV320AIC3206 codec.
To verify that, I load Linux SDK to BeagleBone Black and modify the am335 am335x-boneblack.dts (see the attached file am335x-boneblack.dts on the bottom).
I boot the board with this changed am335x-boneblack.dts, use aplay to playback the sample ALSA wav file:
aplay /usr/share/sounds/alsa/Front_Left.wav
However, I get the errors:
