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.
