[SOLVED] [Orange Pi with A20 CPU]: Booting from SATA - mSD still boots

Hi,

I'm trying to boot from SATA the original OrangePI:

Using the Jessie "Linux orangepi 4.9.12-sunxi #4 SMP Thu Feb 23 19:46:51 CET 2017 armv7l GNU/Linux"

Followed this thread: https://forum.armbian.com/index.php/topic/329-moving-linux-to-sata-or-external-drive/

- copied to /dev/sda1

- edited /boot/boot.cmd and changed to /dev/sda1

- edited the mounted sda1 fstab and changed / to SATA drive UUID 

- compiled: mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

Rebooted but Orange Pi still boots from mSD card and does not use SATA drive.

Question: Should I use UUID of the SATA drive in /boot/boot.cmd?
