you will have to either
	compile u-boot for the orange-plus so that it will look for the correct dab file
	depending which one you are using, it’s probably looking for orange-pc
	(do a grep dtb of the u-boot - which should be in the fat partition)

or
	figure out how to set/create the txt file u-boot is supposed to read, and what is the correct
	magic syntax to set the dub file name
