All I wanna do is get the kernel + dtb from this volume for stand-alone boot. Meanwhile I'm getting both files using tftp from the server - but that's no long term solution. I'm still curious why we get 0x000000000000-0x000040000000 : "mtd=0" -> 0 ! and UBI error: ubi_init: cannot attach mtd2 -> 2 ! Is this the expected behaviour ? Regards, Andr?
