Debian Wheezy Instructions
Contents
Availability
An SD Card image for a Debian system for odroid-u2 is available in the downloads area Debian-wheezy
The files with the .md5sum extensions give you an easy way to check validity after downloading, using md5sum like this:
md5sum -c odroidu2_20130104-debian-wheezy-3.img.xz.md5sum # odroidu2_20130104-debian-wheezy-3.img.xz: OK
The non-filesystem area, including the bootloader(s) are identical to odroidu2_20130104-linaro-ubuntu-desktop-uSDeMMC.img.xz, that is why the first part of the file names match. The kernel is in the second partition and it IS different from odroidu2_20130104 -- it has stability improvements
debian-wheezy describes the system, the -3 is a version number, .img means it is a SD card image and .xz shows the file compression type.
Revision History
debian-wheezy-2 initial release
debian-wheezy-3 Added curl package, updated to kernel 3.0.57
Features
Writing the image to SD card and booting will give you a completely pristine, up-to-date, headless Debian 7.0 system. Headless, meaning only the Linux console is active -- not the HDMI display.
The network will come up automatically, using DHCP.
The login is: user/password or root/root. Specifically, this means username: user and password: password will get you in. Or you can use username: root password: root. Yes, I do let root log in to the console...
If you log in as user, you can su to become root.
Root Filesystem Images
The tarball with the -rootfs.tgz suffix is just the content of the rootfs partition of the SD card.
If you have flashed the Ubuntu SD-Card image and want to try the Debian system, you can just mount the partition, delete all the files and then extract the tarball onto the SD card.

Image Creation Details
This is where I plan to detail how the image was created, starting with odroidu2_20130104-linaro-ubuntu-desktop-uSDeMMC.img.xz and then using debootstrap.
Maybe I'll do a buildroot image first...
