ODROID-XU4 USER MANUAL
xzutils package from
, making sure to select
the OSX binaries, and use it to uncompress the image:
$ xz -d <path-to-compressed-image-file>
Other differences are that the block size (bs) parameter for the
“dd” command is in lowercase, and the USB adapter’s device name
is in the format /dev/diskX. Before writing the image to SD Card or
eMMC module using the “dd” utility, run the command “diskutil” to de-
termine the device name, then unmount it:
$ diskutil list
$ diskutil unmountdisk /dev/diskX
$ sudo dd of=/dev/diskX bs=1m if=<path-to-uncompressed-image-file>
Inserting the eMMC Module or SD Card
Now that the desired image has been flashed on to the boot me-
dia, it’s time to insert the boot media into the appropriate port on the
XU4. Ensure that the work area is clear of unnecessary items. Wear
the grounded wristband. Touch a metallic surface, like that of your desk-
top. Then, open the XU4 packaging box. Place the anti-static bag con-
taining the XU4 board, on to the non-conductive work surface. Open
the bag and remove the board, holding the edges. Avoid touching any
of the components, peripheral connectors, ports, exposed circuits or
on board solder. Place the board on the work surface, with the bottom
side up. Check the annotated diagrams and follow the instructions from
Chapter 1 for inserting the eMMC module or SD card.
Powering Up
Before powering the board, attach all peripherals as described in
Chapter 1. Insert the power cable, which will be indicated by the red
LED lighting up, and wait for the image to boot to desktop. It will take
anywhere from 20 seconds to 2 minutes for the desktop to appear,
depending on the operating system and the type of boot media used.
Troubleshooting
Red LED not glowing
If the red LED is not glowing, power is not being supplied to
the board. Check the connections, and verify that the plug is insert-
ed properly. Also, make sure that a supported 5V/4A power supply
is being used, and that it is plugged in properly. Depending on the
peripherals attached, you may need a more powerful power supply,
such as one rated at 5V/6A+. If the first power supply doesn’t work,
try another supported model. If neither work, seek to RMA the XU4.
