Store root filesystem on a SD card

The default boot environment is built to run form the first partition of an ext4 formated SD card. It is seen as mmcblk1p1 from the target.
Warning, important this operation is risky for your development host: you can simply crash your system. Please pay attention while running these actions.

  • format the SD card as an ext4 volume
  • mount the SD card on your host
  • as superuser, extract the rootfs archive on the SD card:
    # cd <SD card mount point>
    # sudo tar xvaf atmel-xplained-demo-image-sama5d2-xplained.tar.gz
  • unmount the SD card to synchronize its content:
    # umount <SD card mount point>
  • insert the SD card in the board's SD slot
