DIP Switch Settings
(SW402) Switches 1, 2, 4
OFF, OFF, OFF
OFF. OFF, ON
ON, ON, X
For example, when DIP switches 1, 2, and 4 are in the OFF position as shown above, the system first tries to boot from
on-board eMMc memory. If this boot fails the system searches for an SD Card to boot from. If booting from the SD
Card also fails, the system tries to boot from the USB OTG port.
When switches 1 - 2 are in the OFF positions and switch 4 is in the ON position, the system tries to boot from the
microSD card as its first option. If booting from an external source is required, such as when updating the software
for the on-board eMMC memory, booting from the SD card is the preferred option as no external host machine or
additional software is required. If this boot fails, the system attempts to boot from the USB OTG port. Note that when
the microSD card is selected as the primary boot option, no attempt will be made to boot from the eMMC memory.
When switches 1 - 2 are in the ON position, switches 3 and 4 are don't care. In this case, only a boot from the USB
OTG port will be attempted. If this boot fails, no attempt is made to boot from either the microSD card or the eMMC
memory. Although the ARTIK development platform supports numerous USB ports, it only allows boot-up from the
USB OTG port. No other USB ports can be used to boot the system. This option is NOT recommended due to the
complexities required to write the boot image into the eMMC memory, including the requirement for connection to
a Linux host.
For more information on the boot process, refer to the document entitled ARTIK 530s System Design Guide.
