The dts file is attached.

When testing a custom kernel, it is recommended that you create a backup of

the original kernel and add a new entry to this file so that the device can

fallback to the original kernel. To do this:

1, Make a backup of the original kernel

sudo cp /boot/Image /boot/Image.backup

2, Copy your custom kernel into /boot/Image

3, Uncomment below menu setting lines for the original kernel

4, Reboot

LABEL backup

MENU LABEL backup kernel

LINUX /boot/Image.backup

INITRD /boot/initrd

APPEND ${cbootargs}

Also where should the dtb file be copied?

/boot/dtb/kernel_XXX.dtb

or

/boot/kernel_XXX.dtb

Thank you
