That works ... great !! But now I'm confused, since I thought the DTB was appended to the uImage file. I have the following in my .config:- ARM_ATAG_DTB_COMPAT=y ARM_APPENDED_DTB=y ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER=y And then I create my uImage file using:- $ make -j 8 ARCH=arm CROSS_COMPILE=arm-linux- uImage $ make -j 8 ARCH=arm CROSS_COMPILE=arm-linux- am335x-bone.dtb $ cat arch/arm/boot/uImage arch/arm/boot/am335x-bone.dtb > arch/arm/boot/uImage-dtb.am335x-bone $ cp arch/arm/boot/uImage-dtb.am335x-bone /media/boot/uImage Do you now have to load the DTB as a separate file ? Or should the appended DTB still work ?
