Flash only a new Device Tree to Colibri iMX7

Would anyone be able to help us with U-Boot instructions for flashing just a new DTB ? The flashing instructions for iMX7 from here do not seem to have a command for updating just the DT. From looking at the environment variables in U-Boot we see the following:

load mmc 0:1 ${fdt_addr_r} ${soc}-colibri-${fdt_board}.dtb

Would this be enough as long as the imx7d-colibri-eval-v3.dtb is present on the sd card (mmc:01) ?

Any examples on printing from uboot the loaded device tree would be helpful as well.
As way to check if the desired device or components are defined or not.

What’s wrong with using our regular update_fdt?

No that command only loads the device tree into memory.

You can use individual update commands. Just make sure to use run prepare_ubi before doing so. I updated the documentation:

Flashing Embedded Linux to iMX7 Modules

Got it. Thank you very much. Once you run setupdate the other commands are created and run update_fdt is there and everything you need.
