TMDSEVM5517: About audio-preprocessing demo

Genius 5840 points
Part Number: TMDSEVM5517

Hello.

I am evaluating audio-preprocessing demo following below document.

http://www.ti.com/lit/an/spracn7/spracn7.pdf

The demo works well with 4 mics on PCM1864CMBEVM.

Could you tell me how to run the demo with 6 mics on PCM1864CMBEVM?

I modified codec_pcm186x.h as below.

-----

// #define NUM_OF_MICS 4

#define NUM_OF_MICS 6

-----

But following build error exist.

-----

...Initializing DRC

Not enough heap, exiting

-----

Are there any additional modifications to run 6 mic audio-preprocessing demo?

Regards,

U-SK
