8MIC-RPI-MX8 support for i.MX 8M Nano EVK

[Steves1969]

Is there software support for 8MIC-RPI-MX8 on i.MX 8M Nano EVK?

The mic array is listed as an accessory for the  i.MX 8M Nano EVK but not sure where to start to develop an application, Linux, Android, RTOS, SDK.....

Hello Steves1969,

Yes, on linux BSP the following Linux kernel configurations are provided for this module:
• CONFIG_SND_IMX_MICFIL - Configuration option for PDM Microphone Driver
• Device Drivers -> Sound card support -> Advanced Linux Sound Architecture >
ALSA for SoC audio support -> SoC Audio for Freescale i.MX CPUs -> SoC Audio
support for i.MX boards with micfil

Also you can view on your linux documentation chapter 7 about the microphone interface.
