Yes, they're from before my commit. I tried to maintain backward = compatibility but it just wasn't possible. You need to generate new dtb files and = place them on FAT partition. You can also install sys/modules/dtb/am335x to SD card = and set U-boot fdt_file env variable to beaglebone-black.dtb and loader = should be able to find this file and load it. I've never used this approach = myself, but it should work with recent ubldr I think.=20 =20
