Enabling PWM in IMX93EVK

Robbi — Tue, 11 Feb 2025 12:23:32 GMT

Hi team,

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

They had provided 2 dts files :
imx93-11x11-evk-pwm-led.dts
imx93-11x11-evk-pwm.dts
I copied these 2 files in u-boot-imx/git directory.
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.
Added
dtb-$(CONFIG_ARCH_IMX9) +=imx93-11x11-evk-pwm-led.dtb in Makefile.
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.

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!
