Thanks for your response.

Is there any straight forward working application for pdm mic?

Looking for your response.

Thanks

That error means your device tree overlay is missing or has a mistake in it.

There is an introduction to device tree in the dev academy Fundamentals course.

I have resolved the above build error with few changes in header files.

Moreover, I need your support for further build error which I'm facing now.

Here I'm attaching the build error image for your reference

please support me as soon as possible.

Thanks in advance

What NCS SDK version? I use the driver header from zephyr/audio/dmic.h in SDK 3.2.1 version.
