Alternatively, if your U-Boot does not support loading a DT, you can enable the ARM_APPENDED_DTB option in the kernel, and append the .dtb file to your kernel image, like this: cat path/to/zImage path/to/board.dtb > zImageWithDT The resulting file can be passed to U-Boot's “mkimage” as a normal kernel. With this options, if the kernel detects that a DT has already been loaded by the bootloader, it will use it, otherwise it will try to read the .dtb file that has been appended to it. Cheers, -Adrian
