How do I

Q: How do try out my image on a hard disk?

A: bitbake core-image-sato or core-image-sato-sdk

1. have a suitable partition on the disk - say partition #3
2. this partition will show up as sde3 on my host machine and sda3 on the atom
3. mkfs.ext3 /dev/sde3
4. mount /dev/sde3 /mnt/target
5. mount -o loop tmp/deploy/images/core-image-sato-sdk.ext3 /mnt/target-ext3
6. cp -a /mnt/target-ext3/* /mnt/target
7. grub-install --recheck --root-directory=/mnt/target /dev/sde

If grub install passed, copy the following to /mnt/target/boot/grub/grub.cfg

set default="0"
set timeout="30"

menuentry 'Yocto SDK' {
      insmod part_msdos
      insmod ext2
      set root='(hd0,msdos3)'
      linux /boot/bzImage root=/dev/sda3
}

Thats it - this boots for me.
