 root device not found. Sorry that I don't have exact error messages but
 the device does not boot so I cannot copy them directly.

 This change may work if you are booting from a USB. [[BR]]
 If you are booting from a single partition SDcard, try changing
 root="/dev/disk/mmc/mmc${tmp}p2"  to root="/dev/disk/mmc/mmc${tmp}p1"
 [[BR]]
 Though it might be simpler to use a simple /boot/olpc.fth and point it
 directly to your initrd.img and vmlinuz in the SDcard.
