1 How to use U-Boot on PHYTEC phyBOARD-i.MX6UL-Segin
2 --------------------------------------------------
4 - Configure and build U-Boot for phyCORE-i.MX6UL:
7 $ make phycore_pcl063_defconfig
10 This will generate SPL and u-boot-dtb.img images.
12 - The SPL and u-boot-dtb.img images need to be flashed into the micro SD card:
14 $ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
15 $ sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
19 JP1: Open: Boot from NAND
20 Closed: Boot from SD/MMC1
22 - Connect the Serial cable to UART0 and the PC for the console.
24 - Insert the micro SD card in the board and power it up.
26 - U-Boot messages should come up.
