Is it possible to use mfgtool to program/update DTB file only to i.MX6Q SABRE board (Android M6.0.1_2.1.0 GA)?

I checked ucl2.xml and found for eMMC-Android, no DTB file is involved, means for android, no DTB required? then how I can set the device tree.

if you need to build kernel, you need to use toolchian, mfgtools is for download image to your board,you can refer to the document as below:

for path, you can find the dts file under:

fsl-release-bsp/build/tmp/work-shared/imx6qsabresd/kernel-source/arch/arm/boot/dts

The device tree is part of the boot.img. You can unpack the boot.img and re-pack it with your device tree.

Got it clear that even there is a minor modification only in dts file, I need re-program the boot.img again.
