1How to use U-Boot on variscite DART-6UL Evaluation Kit 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 12Boot 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 23Boot 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. 42
