Installing Debian on an Odroid U2.

Posted on 11, Jan 2014

The Hardkernel Oroid U2 is a tiny quad-core computer running a Samsung Exynos4412 - a similar processor to that found in the Samsung Galaxy S3. There is a loose guide for installing Debian on the U2 here , however what follows is meant to be more comprehensive.

Downloads

This guide uses the Debian Wheezy Base (version 7.1.0) image found at odroid.us , you will probably want the most current version available from the same site.

wget http://odroid.us/odroid/odroidu2/debian/debian-wheezy-base-7.1.0.img.xz
wget http://odroid.us/odroid/odroidu2/debian/debian-wheezy-base-7.1.0.img.xz.md5sum

Now we will check the validity of our downloaded image:

md5sum -c debian-wheezy-base-7.1.0.img.xz.md5sum

We want to see OK as output from this, not FAILED for example. Finally, extract the downloaded image:

xz -d debian-wheezy-base-7.1.0.img.xz

Flashing the SD Card

Insert your micro SD card into a reader, if it auto-mounts, unmount it.
Now all we have to do is write the image to the SD card using dd :

sudo dd if=debian-wheezy-base-7.1.0.img of=/dev/mmcblk0
sync

If you see errors suggesting that your SD card is set to read-only, you can try this before using dd :

sudo hdparm -r0 /dev/mmcblk0

Insert the card into your U2, turn it on, and you should be away.
