Enabling PWM in IMX93EVK

[Robbi]

Hi team,

                  I am try to blink led on IMX93EVK using PWM based on document provided by NXP.

1.   They had provided 2 dts files :
   imx93-11x11-evk-pwm-led.dts

   imx93-11x11-evk-pwm.dts
2. I copied these 2 files in u-boot-imx/git directory.
3. And changed
   CONFIG_DEFAULT_DEVICE_TREE="imx93-11x11-evk-pwm-led" , 

   CONFIG_DEFAULT_FDT_FILE="imx93-11x11-evk-pwm-led.dtb"
   imx93_11x11evk_defconfig file.
4. Added 
   dtb-$(CONFIG_ARCH_IMX9) +=imx93-11x11-evk-pwm-led.dtb in Makefile.
5. Final performed build, but there is no change in the image.

Please guide me the steps to test below PDF and steps to configure dts file.

How/where  to add below two files and because I am seeing work/work-shared directory.

Thanks Robbi.

Hi @Robbi!

Thank you for contacting NXP Support!

The device tree files should be applied in Linux Kernel not in u-boot device tree.

You can compile the device tree file using this guide.

Best Regards!
