IMX6ULL Change device tree file that is used

When i run ‘run update_ftb’ i get

Colibri iMX6ULL # run update_fdt
reading colibri-imx6ull/imx6ull-colibri-wifi-eval-v3.dtb

I have created my own dtb file which is built and placed onto the SD card

How do i change which file the ‘run update_fdt’ is using ?

I have tried ‘setenv fdt_file imx6ull-colibri-adrian.dtb’ and this made no difference

Apparently you cant change the whole name, but just the extension

To change the default devicetree you can do the following in U-Boot:

setenv fdt_board=xxxxx


It will then load the file imx7d-colibri-emmc-xxxxx.dtb.
