Setting the Boot Mode

Follow the instruction below according to the appropriate carrier board type:

MX6CustomBoard

Booting your MX6CustomBoard system from SD card requires pushing the middle button while powering up the system. See picture below.

To boot a board using an SD card, follow the steps below:

Power-off the board.
Insert the SD card into the SD/MMC slot of the carrier board (DVK)
Push the middle button (Boot Select) and hold
Power-up the board
Release the middle button (Boot Select) after system starts to boot.
The board will automatically boot into Linux from the SD card

SoloCustomBoard

Booting your system requires switching the relevant DIP switch to "Boot from MMC". See picture below.

To boot board with SD card, Follow the steps below:

Power-off the board.
Insert the SD card into the SD/MMC slot of the carrier board (DVK)
Switch the relevant DIP switch to "Boot from MMC"
Power-up board
The board will automatically boot into Linux from SD card

DT6CustomBoard

Booting your system requires switching the relevant DIP switch to "Boot from SD card". See picture below.

To boot board with SD card, Follow the steps below:

Power-off the board.
Insert the SD card into the SD/MMC slot of the carrier board (DVK)
Switch the relevant DIP switch to "Boot from SD card"
Power-up board
The board will automatically boot into Linux from SD card

Setting the Boot Mode

Booting your system from an SD card requires switching the Boot DIP switches. See picture below.

"00" The current position in the picture will set the system to boot from SD card.
"01" Moving the right switch will set the system to boot from eMMC
"10" Moving the left switch will set the system to boot from NAND flash
"11" is illegal.

Be aware that your system has eMMC or NAND but never both.

Automatic device Tree selection in U-Boot

Upon reset you will see the U-Boot SPL printouts. It will print also the SOM configuration:
On-SOM storage: SD only, eMMC, NAND.
WIFI if chip exits.
For example:

U-Boot SPL 2015.10-00532-g482dc88 (Jan 03 2016 - 10:05:42)
i.MX6UL SOC 
Part number: DART-6U-A01
Assembly: AS11
Date of production: 2015 Dec 31
DART-6UL configuration: eMMC WIFI
Ram size: 512
Boot Device: SD

As explained in the above Build Results table we have 4 optional configurations.
We implemented in U-Boot and automatic device tree selection, so when kernel boots, the U-Boot will load the corresponding device tree according to On-SOM configuration.

SOM Type	Boot From	SOM Internal FLASH	SOM has WIFI/BT	Device Tree selected
DART-6UL	SD	eMMC	Don't Care	imx6ul-var-dart-sd_emmc.dtb
DART-6UL	SD	NAND	Don't Care	imx6ul-var-dart-sd_nand.dtb
DART-6UL	eMMC	eMMC	Yes	imx6ul-var-dart-emmc_wifi.dtb
DART-6UL	eMMC	eMMC	NO	imx6ul-var-dart-sd_emmc.dtb
DART-6UL	NAND	NAND	YES	imx6ul-var-dart-nand_wifi.dtb
DART-6UL	NAND	NAND	NO	imx6ul-var-dart-sd_nand.dtb
DART-6ULL	SD	eMMC	Don't Care	imx6ull-var-dart-sd_emmc.dtb
DART-6ULL	SD	NAND	Don't Care	imx6ull-var-dart-sd_nand.dtb
DART-6ULL	eMMC	eMMC	Yes	imx6ull-var-dart-emmc_wifi.dtb
DART-6ULL	eMMC	eMMC	NO	imx6ull-var-dart-sd_emmc.dtb
DART-6ULL	NAND	NAND	YES	imx6ull-var-dart-nand_wifi.dtb
DART-6ULL	NAND	NAND	NO	imx6ull-var-dart-sd_nand.dtb

Note: Boot from SD card eliminates Wifi as the Wifi and SD card are using same SDIO interface.
A typical use-case, is to boot from SD card, flash eMMC or NAND flash, and re-boot form eMMC/NAND to have Wi-Fi operational.
