Hi,

 

My development hw setup : IMX8M Mini EVK Interfaced to ADAU7002 with PDM MIC (2 Nos)

Yocto Linux BSP 4.14.98.2.0.0

 

adau7002.c is availlable in the kernel and I built into the kernel.

the machine driver for adau7002 i have created and added to the kernel and built.

 

dts file i have created one, similar to ak5558 enabling the adau7002 and disabling micfil.

I have edited the Makefile in arch/arm64/boot/dts/freescale/Makefile, to add the fsl-imx8mm-evk-adau7002.dtb file.

But when i built the linux-imx module. I am not getting the dtb file generated in the build.

 

Could you please tell me where i am doing wrong. I checked the ubuntu machine for dtc compiler it is available.

But it is not generating the dtb file for the fsl-imx8mm-evk-adau7002.dts ==> fsl-imx8mm-evk-adau7002.dtb

 

Could you please let me know, any other place i need to add any.

 

Thank you, Sreedhar
