SD Boot

Create Single partition and Insert the SD on host

$ cd /path/to/u-boot
$ ./tools/mkimage  -n rk3399 -T rksd -d /path/to/rkbin/bin/rk33/rk3399_ddr_800MHz_v1.20.bin idbloader.img
$ cat /path/to/rkbin/bin/rk33/rk3399_miniloader_v1.19.bin >> idbloader.img

$ sudo dd if=idbloader.img of=/dev/sdc seek=64
$ sudo dd if=trust.img of=/dev/sdc seek=24576
$ sudo dd if=uboot.img of=/dev/sdc seek=16384
$ sync
