fasted way to compile device tree in Yocto Imx?

[listplot3d]

with a imx6ul evk board, I need to change device tree and have quick test. More specifically, I want to build the imx6ul-14x14-evk.dtb only.

What's the most efficient way to do that?

Thanks & Regards

after executing following command, dtb file can be found under <fsl directory>/fsl-release-bsp/build_imx6ulevk/tmp/deploy/images/imx6ulevk

cd /home/dev/IMX/fsl-release-bsp

DISTRO=fsl-imx-x11 MACHINE=imx6ulevk source fsl-setup-release.sh -b build_imx6ulevk

bitbake linux-imx -f -c deploy

alternative ways can be found from below. but I found above as the simplest.

It seems that this method is currently not possible.
DTS is not COMPILE in Yocto Project 4.0 (Kirkstone), LF5.15.52_2.1.0.

It takes time, but you need to add a compile process. (Takes about 1 minute.)
bitbake -f -c compile linux-imx
bitbake -f -c deploy linux-imx
