    352352Boards with an Alternate boot device also have a boot watchdog such that if the current boot device fails to boot within 30 seconds, the board will power cycle primary power and attempt boot from the other boot device.

     354The bootloader also has a notion of boot device, either the built in eMMC or an external microSD.
     355This is controlled through the UBoot variable 'dev'.

     357Note if booting with the onboard eMMC as the primary boot device, “0/mmcblk0” is the U-Boot/Linux device node for eMMC and “1/mmcblk1” is the U-Boot/Linux device node for microSD. When booting from the alternate device (microSD) this is swapped.
