Creating bootable SD card:
==========================

Simply invoke (as root)

sudo dd if=output/images/sdcard.img of=/dev/sdX && sync

Where X is your SD card device.

Booting:
========
Orangepi-RK3399 by default boots from emmc. For SD card boot to
happen, emmc should be empty. If emmc happens to have any bootable
image then erase emmc so that bootrom will look for a proper image in SD.

emmc can be erased once after booted into linux as shown in below link.
