{{InfoBoxBottom}}
== System boot ==
The boot process begins at Power On Reset (POR) where the hardware reset logic forces the ARM core to begin execution starting from the on-chip boot ROM.
For the iMX6 processor and the selected boot mode on DAVE's SOMs, please find more information at [[Boot_options_(AxelLite) | Boot AxelLite]] and [[Booting_from_NAND_flash_on_i.MX6-based_platforms | Booting from NAND]] wiki pages.
== Boot switch ==
There is a specific 2x1x2.54mm pin header on the [[SDV04 | SDV04]] carrier board for selecting the storage boot device.
Inserting a jumper on the left position header, the internal storage device is selected as a primary boot device: i.e. NOR SPI or NAND flash.

At the opposite, if it is not inserted, the external SD card (properly programmed and inserted into the microSD connector) is used as a primary boot device.
