Booting the Board From SD Card

To boot your board from an SD card and enable persistent rootfs, follow these steps.
You can also use this procedure to boot your board from a USB stick or eMMC.
If you are using an Intel® Galileo board, this setup allows you to save your Arduino*
sketch to the board, so it will be able to repeat sketches after board power-down. This
also enables a persistent /sketch folder and rootfs.
Dependencies:
 You ran the command bitbake image-full in Section 6
 Your SD card must meet the following requirements:
 SD card must be formatted as FAT or FAT32.
 SD card size must be 32GB (or smaller) and SDHC format. SDXC format is not
supported.
1. The output of the build process in Section 6 is found in
./tmp/deploy/images/quark/
Copy the following kernel and root file system files to an SD card:

boot (directory)

bzImage

core-image-minimal-initramfs-quark.cpio.gz

image-full-quark.ext3
Be sure to set up your SD card with the files and structure shown as follows.
2. Insert the SD card, then power on the board.
The first time you boot the board may take several minutes. This is expected
Note:
behavior due to the SSH component creating cryptographic keys on the first boot.
