Is it because the cape only uses one of the I2C ports and one of the audio
in/out ports?

Hi Colin,
I have decided to forgo the CS42448 board for now, as its Evaluation board
a codec board, and instead I am going to see if I can figure out stacking
the audio capes with the BBB, and how the BBB does multichannel audio...
and if that doesn't work, I might have to try the external board.
Hi,
I've been trying to work with the CS42448 audio codec as a peripheral for
the STM32F405 Discovery Board, but with little success. I'm also very
interested in porting the codec over to the BB and the Raspberry Pi (any
ARM processors, really). If you have any information or code you'd be
wil
Wait, that's pretty cool. I will forward this to my group, and see what
they think.
Thanks for the suggestion/idea!

Interesting. Are you keen to
Ah, I see. Thanks for the help!
My general idea so far is to stack 3 audio capes to receive 6 channel
input, then process and output probably stereo (or 6 channel out for
feedback); I guess I'll see how the multiplexing will fit in once I
understand the board more.

We just used a proto cape to expose the McASP pins we needed, then ran
wires over to a set of TI SmartAmp boards which supported TDM at the time.

ooh that's pretty cool! Hopefully it will work for me as well.
Did you have to build your own TDM cape, or could you just stack them and
use the Am335x to do the multiplexing

I think I tested 8 or 16 CH TDM at 48k and it worked fine.

We were considering that, but were concerned if we could find a fast enough
mux to do 6 channels at 48kHz, and that plus clock issues.
Thanks for the idea, though! I will check out how the Am335x fares in TDM.

You could make a stackable TDM cape I guess?
Each codec/cape board could pick off its own channel from the McASP/TDM
port...
I like that idea...
