Hi All,

We are using DM385 with IPNC RDK,

As per description McAsp is capturing audio in I2S format from Audio Chip on EVM.

Now, In our custom board we need to capture Audio from MEMS INMP441 in I2S format.

INMP441 chip doesn't require any type of configuration. It directly provides I2S output after getting clock from master.

Can you please suggest us what changes need to do in kernel source ?

Thanks in advance,

Regards Kalpesh

Hi Kalpesh,

Did you configure the I2S driver (address and other information if needed) in your customer board?

Thanks for your feedback.
We are able to Interface inmp441 on IIS with DM385 and Sound quality is good.
