see http://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html
section 5.6

ideally take sdcard image from beagleboard.org and dd if=sdcard.image
of=/dev/sdX
which sdX is where sdcard is on your machine. this will prepare the card
along with image. Now you can mount the partitions individually and
replace the files
as you wish
