Contents
Image Files
First a reminder about my images. *.img.xz means it is a compressed multi-partition image. You need to use xz to decompress it before writing it to SD Card.
- .rootfs.tgz is just the root file system partition contents. Only needed to quickly get back to the original flash contents
- .boot.tgz is just the boot partition contents. Only needed in case you wreck something and can no longer boot.
- .md5sum are md5 checksum files you <should> use to make sure the associated file was downloaded properly.

Files
Look for the files here: http://odroid.us/odroid/odroidxu/debian/
Details on how the image was built are here: debian-jessie-armel-7.1-odroidxu Build Notes
Kernel Build
There is some issue with the default default config from github, it will not compile. Here is a snippet showing how I worked around it
// Fetch kernel source mkdir -p /usr/src 2>/dev/null cd /usr/src/ git clone --depth 1 https://github.com/hardkernel/linux.git -b odroidxu-3.4.y linux-3.4.y # cd linux-3.4.y # pick up configuration that will build wget http://odroid.us/odroid/odroidxu/patches/odroidxu_ubuntu_more_netfilter_stuff cp odroidxu_ubuntu_more_netfilter_stuff arch/arm/configs # Use the new config make odroidxu_ubuntu_more_netfilter_stuff # make it make -j8 # ...
Add-ons
This section is for items added on to the base image
hwcomposer
We need a daemon to take care of making video data in the framebuffer show up on the HDMI output. This is called exynos5-hwcomposer. I built it natively on the odroidxu and created a Debian package that others can use. (this package is only for odroidxu and only for armel -- soft floating point). The as-built tarball is in the same directory in case you want to rebuild from source.
Get and install the package as root user on the odroidxu:
wget http://odroid.us/odroid/odroidxu/debian/packages/exynos5-hwcomposer-3.4.75-1_armel.deb dpkg -i exynos5-hwcomposer-3.4.75-1_armel.deb <pre> === Steps === You don't need to go through these steps if you are able to use the package mentioned above (exynos5-hwcomposer-3.4.75-1_armel.deb) I found mdjr's instructions on how to build hwcomposer on the forum: [http://forum.odroid.com/viewtopic.php?f=61&t=2207 http://forum.odroid.com/viewtopic.php?f=61&t=2207] This is what I did: <pre> # Get latest version git clone --depth 0 https://github.com/hardkernel/linux.git -b odroidxu-3.4.y odroidxu-3.4.y cd odroidxu-3.4.y/tools/hardkernel/exynos5-hwcomposer sh autogen.sh ./configure --prefix=/usr make -j5
Edit /etc/rc.local so it starts exynos5-hwcomposer at boot, The sleep is necessary to give a chance for other startup processing to be done. I was finding that sometimes hwcomposer would not start -- or I would be nothing on the HDMI
# ... # By default this script does nothing. sleep 5 # Start hwcomposer to route framebuffer output to HDMI /usr/bin/exynos5-hwcomposer & # Mount the boot partition mount -o ro /dev/mmcblk0p1 /boot # ...
