How to use U-Boot on variscite DART-6UL Evaluation Kit
------------------------------------------------------

- Configure and build U-Boot for DART-6UL iMX6ULL:

    $ make mrproper
    $ make variscite_dart6ul_defconfig
    $ make

  This will generate SPL and u-boot-dtb.img images.

Boot from MMC/SD:
- The SPL and u-boot-dtb.img images need to be flashed into the micro SD card:

    $ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
    $ sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync

- Boot mode settings:

  Boot switch position: SW1 -> 0
			SW2 -> 0

Boot from eMMC:
- if bootpart is not enabled by default, to enable under Linux
	echo 0 >/sys/block/mmcblk1boot0/force_ro
	mmc bootpart enable 1 1 /dev/mmcblk1boot0

- Flash the SPL and u-boot-dtb.img to mmcblk1boot0
    $ sudo dd if=SPL of=/dev/mmcblk1boot0 bs=1k seek=1; sync
    $ sudo dd if=u-boot-dtb.img of=/dev/mmcblk1boot0 bs=1k seek=69; sync

- Boot mode settings:

  Boot switch position: SW1 -> 0
			SW2 -> 1

- Connect the Serial cable to UART0 and the PC for the console.

- Insert the micro SD card in the board and power it up.

- U-Boot messages should come up.
