| 2 | ------------------------------------------------------ |
| 3 | |
| 4 | - Configure and build U-Boot for DART-6UL iMX6ULL: |
| 5 | |
| 6 | $ make mrproper |
| 7 | $ make variscite_dart6ul_defconfig |
| 8 | $ make |
| 9 | |
| 10 | This will generate SPL and u-boot-dtb.img images. |
| 11 | |
| 12 | Boot from MMC/SD: |
| 13 | - The SPL and u-boot-dtb.img images need to be flashed into the micro SD card: |
| 14 | |
| 15 | $ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync |
| 16 | $ sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync |
| 17 | |
| 18 | - Boot mode settings: |
| 19 | |
| 20 | Boot switch position: SW1 -> 0 |
| 21 | SW2 -> 0 |
| 22 | |
| 23 | Boot from eMMC: |
| 24 | - if bootpart is not enabled by default, to enable under Linux |
| 25 | echo 0 >/sys/block/mmcblk1boot0/force_ro |
| 26 | mmc bootpart enable 1 1 /dev/mmcblk1boot0 |
| 27 | |
| 28 | - Flash the SPL and u-boot-dtb.img to mmcblk1boot0 |
| 29 | $ sudo dd if=SPL of=/dev/mmcblk1boot0 bs=1k seek=1; sync |
| 30 | $ sudo dd if=u-boot-dtb.img of=/dev/mmcblk1boot0 bs=1k seek=69; sync |
| 31 | |
| 32 | - Boot mode settings: |
| 33 | |
| 34 | Boot switch position: SW1 -> 0 |
| 35 | SW2 -> 1 |
| 36 | |
| 37 | - Connect the Serial cable to UART0 and the PC for the console. |
| 38 | |
| 39 | - Insert the micro SD card in the board and power it up. |
| 40 | |
| 41 | - U-Boot messages should come up. |
