How to modify .dts in uboot?

[James33]

Hi !  I'm debugging the development board based on the IMX93 series chips and encountered some issues while modifying the uboot file imx93-11x11-evk.dts. The compiled imx-boot.tagged doesn't seem to take effect after my modifications. Even when I added meaningless content like "" to the .dts file, the compilation still succeeds without any errors.
yocto version： scarthgap imx-6.6.52_2.2.0

command：bitbake -c compile -f u-boot-imx

Hi,

Please use 'devtool modify u-boot-imx' to unpack uboot source code into build_xx/workspace/sources/u-boot-imx, then modify code.
