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
Hello Sreedhar,
Below is our last discussion:
For your question, follow these 2 steps, please!
1. Add your new dts file to local Makefile .
2. run "bitbake linux-imx -f -c compile" on command line
Use above method, new .dtb has not been created yet.
Retry this command:
Let me assume your image is : core-image-base
then we can force compiler to re-compile the image.
# bitback core-image-base -f
[comment]
here core-image-base can be replaced with yours.
Hope above information can help you.
Have a nice day!

Hi,
thank you for the suggestion:
I am working with Yocto Linux BSP 4.14.98.2.0.0.
I edited the Makefile in the arm/arch64/boot/dts/freescale/Makefile
and included my created .dtb file in it.
As mentioned above, i bitbaked using the below command
bitbake fsl-image-validation-imx
sdcard image is created but the created dts file dtb is not generated. Could you please tell me any step i am doing wrong / missing.
Thank you, Sreedhar
Hello Sreedhar,
It seems that you should run:bitbake -c deploy
Summarize it:
1. bitbake linux-imx -f -c compile
2. bitbake -c deploy
or you can try this command:
# bitbake -c deploy -f -v linux-imx
try it, please!
Have a nice day!
BR,
Weidong
