It was a SD card,,,, in a bit I will blank emmc uboot and try again
ie,, save mbr, save 1st 16M, zero 1st 16M, restore mbr

later
cfdisk seems to think this is a ISO image, anyway there is no partition table and no MBR
Is there no uboot in the first 16M?
How in the world could you boot a dd'd image (onto SD card) unless you had tow-boot on emmc
(or a serial connection, not so easily done on pbp)
