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.
