How do > I do that? ubldr will load the file described by the "fdtfile" u-boot variable (ubldr import the needed uboot variables). The uboot variable is hardcoded in the uboot port patch (https://svnweb.freebsd.org/ports/head/sysutils/u-boot-olimex-a20-som-evb/files/patch-include_configs_sunxi-common.h?revision=418446&view=markup#l44). Alternativelly you can do from ubldr prompt : load -t dtb filename It will search for the file in /boot/dtb (or you can use the fullpath if it's elsewhere) > On my dreamplug I don't use ubldr, but boot kernel.bin directly from > u-boot.
