+It is a little bit risky, as you have to brick your device before knowing if the USB-stick really boots up.
+The board will automatically boot from USB when the internal eMMC is unbootable.\\
+(But the eMMC must still be present. When removed, no boot attempt happens at all)
+To make the eMMC card unbootable:
+  * Boot the device
+  * Log in via a serial connection
+  * Overwrite the bootsector of the eMMC: ''sudo dd if=/dev/zero of=/dev/mmcblk1 bs=512 count=1''
+  * Insert the USB-stick
+  * Restart the device (either via command or the power plug)
+The device will now try to boot from the USB-stick.
