Searching on the Internet I have found only two approaches: 1. Have a dedicated MTD partition for the device tree blob (raw). 2. Have a UBI volume on a partition and store the device tree blob as a f= ile in a = UBIFS partition (this approach also stores the kernel image as a file in th= e same or = different volume). Is anybody using other approach for storing the DTB in flash? What method is more widely used in embedded devices? Best regards, -- = H=E9ctor Palacios
