Booting from SD card:
1. reset U-Boot environment:
env default -a
saveenv
2. prepare U-Boot with boot script:
setenv bootcmd "load mmc 0:1 0x4d00000 boot.scr; source 0x4d00000"
saveenv
or manually:
setenv fdt_name armada-3720-db.dtb
setenv image_name Image
setenv bootcmd 'mmc dev 0; ext4load mmc 0:1 $kernel_addr $image_name;ext4load mmc 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/mmcblk1p2 rw rootwait; booti $kernel_addr - $fdt_addr'
saveenv
