Hmm strange a plain omap2plus_defconfig kernel boots just fine here.
Also boots fine with appended DTB and 0xFFFF using something like:
$ cat arch/arm/boot/zImage arch/arm/boot/dts/omap3-n900.dtb > /tmp/zImage
$ 0xFFFF -m /tmp/zImage -l -b
My boot log is appended in case that provides any clues. Note that
I'm only loading it with -l and not flashing it though.
Regards,
Tony
