ODROID-XU4 USER MANUAL

Flashing an Image

All SBCs require an operating system (OS) for booting. The op-

erating system will be transferred to and reside on boot media, either

built on to the board or attachable to the board. The process of placing

the operating system on the boot media is termed flashing. Given this

process, it is obvious that another computer system will be needed to

flash the image onto the boot media, before the XU4 can boot up.

The flexible XU4 design allows you to use a boot media device

that will be attached to it through an appropriate receptacles on the

board. If you refer to the annotated board image, you can see that

the XU4 supports two boot media types - microSD card or an eMMC

module. They can be obtained from Hardkernel directly, either with

Linux or Android, pre-installed. If you purchased one such device and

if it has a factory-installed image, you can skip the flashing steps in this

section and proceed to the next section.
