ODROID XU4 USER MANUAL
Wait for the download process to complete, then uncompress
the ile using the following command:
$ unxz ./ubuntu-15.04-mate-odroid-xu3-20150710.img.xz
This will result in the uncompressed image ile called ubuntu-
15.04-mate-odroid-xu3-20150710.img. Attach the USB SD card read-
er / writer with the boot media into an appropriate USB port. After a
few moments, check for an entry that corresponds to the USB SD card
reader / writer (Transcend model in this case) using the following com-
mands:
$ cd /dev/disk/by-id/
$ ls *Transcend*
usb-TS-RDF5_SD_Transcend_000000000039-0
This tells us that the write destination path to the boot media is /
dev/disk/by-id/usb-TS-RDF5_SD_Transcend_000000000039-0. Giv-
en this information, we can carefully construct the image copy com-
mand using appropriate input and output paths:
$ cd ~/linux-img
$ sudo dd \
if=./ubuntu-15.04-mate-odroid-xu3-20150710.img \
of=/dev/disk/by-id/usb-TS-RDF5_SD_Transcend_000000000039-0 \
bs=1M conv=fsync
$ sync
The “dd” command is very powerful, so use it with a lot of care.
If incorrect parameters (especially the of parameter) are used here,
you could potentially ruin the OS installation of the computer. The “dd”
command is often referred to as the disk destroyer command.
This step could take a while. So, wait for it to complete before
proceeding. Once completed, remove the USB SD card reader / writer
from the USB port of the computer. Remove the boot media and place
it on the non-conductive surface.
The above steps are to lash the Linux image. To lash an An

earlier, the Android images can be found at
Flashing an Image on an OSX Computer
The procedure for creating an image ile using OSX is similar
to Linux, with some small differences. First, download and install the
