If the '/opt/toolchains' directory does not exist in host pc, then create the directory.

$ sudo mkdir /opt/toolchains
$ sudo cp arm-eabi-4.6.tar.gz /opt/toolchains
$ cd /opt/toolchains
$ sudo tar zxvf arm-eabi-4.6.tar.gz

$ cd /opt/toolchains
$ sudo tar xvfz arm-eabi-4.6.tar.gz

Modify your ~/.bashrc file to add a new path with editor (gedit or vi)

export ARCH=arm
export PATH=${PATH}:/opt/toolchains/arm-eabi-4.6/bin
export CROSS_COMPILE=arm-eabi-

To apply this change, login again or restart the .bashrc

$ source ~/.bashrc

$ arm-eabi-gcc -v

Linux ODROID-XU3 works as follow:

It must have at least two partitions.

First Partition must be a FAT32/EXT4 partition.

Second Partition can be whatever the Filesystem that your kernel supports (must be built in).

Note: It is possible to use the first partition as ext4, however its strongly not recommended due to Windows Users lost the capability of changing boot.ini

Partition 1:

• Kernel Image (zImage)
• boot.scr
• exynos5422-odroidxu3.dtb
• uInitrd (if applicable)

Partition 2:

• rootfs (a.k.a. File System)

• Ubuntu 14.04 Ubuntu 14.04 Forum Thread

Note: More distribution support will come with time.

HDMI support should work out-of-box for everyone including framebuffer console if you experience any issue please contact us on the ODROID Forums

On the provided Ubuntu image there are several examples on how to configure the HDMI to your specific resolution or even lock to a certain resolution. You can check the configuration file on /media/boot/boot.ini of the Ubuntu Image

For displayport configuration please follow this guide Displayport Guide on ODROID Forums

Kernel sources for ODROID-XU3 is on our Github. Branch is odroidxu3-3.10.y defconfig is odroidxu3_defconfig

Please follow the instructions below to rebuild the Linux Kernel for ODROID.

Those instructions cover native build of the Kernel.

1. Install dependencies: apt-get install build-essential libqt4-dev libncurses5-dev git
2. Clone Repo: git clone –depth 1 https://github.com/hardkernel/linux.git -b odroidxu3-3.10.y odroidxu-3.10.y

 git clone --depth 1 https://github.com/hardkernel/linux.git -b odroidxu3-3.10.y odroidxu3-3.10.y 

1. Configure Kernel: make odroidxu3_defconfig
2. Do changes if you need/want: make menuconfig or make xconfig
3. Build Kernel and Modules: make -j9
4. Install zImage: cp arch/arm/boot/zImage /media/boot
5. Install DTB File: cp arch/arm/boot/dts/exynos5422-odroidxu3.dtb /media/boot
6. Install Modules: make modules_install
7. Copy .config to /boot for initramfs creation: cp .config /boot/config-`make kernelrelease`
8. Create initramfs: update-initramfs -c -k `make kernelrelease`
9. Create uInitrd: mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n uInitrd -d /boot/initrd.img-`make kernelrelease` /boot/uInitrd-`make kernelrelease`
10. Install new uInitrd: cp /boot/uInitrd-`make kernelrelease` /media/boot/uInitrd
11. reboot: sync && reboot

Your new kernel should be installed. Note for your own convenience we provide daily builds of Linux kernel that can be easily installed on Supported distros by using a ODROID Utility.
