Hi, 

I hope everything is safe and sound

Currently I'm working with MIMXRT685-EVK and I'm new bee so I started performing demo example for build a understanding towards board. Now i want to enable onboard MIC and perform a sound test on board and I' following MCUXpresso IDE demo example dmic_i2s code for that but can't able to build understanding in right manner. 

Can anyone help me with this?

It would be really appreciate. 

 

Thanks & Regards

Hi @u_h 

Welcome to the NXP product!

Seems this post is the duplicated post as another your post:

https://community.nxp.com/t5/i-MX-RT/Enable-onboard-MIC/m-p/1291733/highlight/false#M14682

Please check my reply, your main issue is caused by the wrong connection with :

JP7-1 <--> JP8-2

 

WIsh it helps you!
