Hi Sir/Madam,

                     I'm working on imx8m mini EVK on Linux environment, I'm modifying the imx8mm-evk .dts file in the kernel-source/aarch/arm64/boot/dts/freescale location after modifying the file I'm building the dts file using bitbake –c menuconfig linux-imx after building the dts file, I'm generating the images using bitbake imx-image-full and copying the images to the sdcard when i'm booting the evk with this sdcard I'm unable to see the pin what i have modified in dts file.

I have modified the device tree and added the dtb file in the u-boot time and booted the EVK board, when I'm exporting the gpio pins and checking the voltage levels using multimeter I'm unable to find the difference I have used Imx8m mini evk and the pin number is MX8MM_IOMUXC_SAI5_RXD1_GPIO3_IO22       0x19 and I have enable the sai5 group in dts file.
