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 ?
Cheers
