How to download and compile the Android kernel for ODROID-XU3/XU4.
You need use gcc version 4.6 to build the Exynos-5422 Android Kernel.
If you have not built Android on your desktop yet, please read Android's official build environment set up guide https://source.android.com/source/initializing.html carefully before you proceed. Otherwise, you may have unexpected errors and will need to read a quite long and complicated build log to find the problem.
We've used Ubuntu 14.04 64bit with 8GB RAM since other newer versions had some issues while building the Android OS.
http://source.android.com/source/requirements.html#hardware-requirements
If you want to build full Android source tree, don't download & build the kernel source separately.
Separated Kernel build might break the Android build process.
Toolchain
Click one of the site to download toolchain to build Linux kernel.
Once the download is done, extract the tarball to /opt/toolchains/.
- host
$ sudo mkdir -p /opt/toolchains $ sudo tar xvfz arm-eabi-4.6.tar.gz -C /opt/toolchains/
In order to add the toolchain path to PATH, paste below lines to $HOME/.bashrc.
- host
export ARCH=arm export CROSS_COMPILE=arm-eabi- export PATH=/opt/toolchains/arm-eabi-4.6/bin:$PATH
You can apply the change if you login again or import to apply this change, login again or evaluate $HOME/.bashrc with source command.
- host
$ source ~/.bashrc
You can check if the toolchain installed above works properly while checking the version of toolchain. If you can find gcc version 4.6.x-google at the end of the line, the toolchain is well installed.
- host

Install the Oracle JDK 6
Oracle JDK 6 is no longer maintained. It is not updated with the latest security patches and are not recommended for use in production. You can however still download them from the Oracle Java Archive http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html
$ java -version java version "1.6.0_45" Java(TM) SE Runtime Environment (build 1.6.0_45-b06) Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
Checkout
You can checkout Kernel source tree from Hardkernel's Github, Android platform source tree from Hardkernel's Github. Please note that we distribute the Linux kernel in different branches for Android and other Linux distributions.
Android Kernel
- host
$ git clone --depth 1 https://github.com/hardkernel/linux.git -b odroidxu3-3.10.y-android $ cd linux
Android Platform
- host
$ mkdir <Android Platform Folder Name> $ cd <Android Platform Folder Name> $ repo init -u https://github.com/hardkernel/android.git -b 5422_4.4.4_master $ repo sync $ repo start 5422_4.4.4_master --all
- Visit this link to install the repo.
http://source.android.com/source/downloading.html
- Downloaded Android full source code size is around 58GB. Prepare enough space before building the Android platform.
Compile
Before compiling, you must configure for ODROID-XU3 with following command.
Android Kernel
- host
$ make odroidxu3_defconfig $ make
Then you can start to build Linux kernel image, zImage-dtb. This will create arch/arm/boot/zImage-dtb. You can also add -j option for fast compile.
Android Platform
- host
$ export PATH=/opt/toolchains/gcc-linaro-arm-none-eabi-4.8-2014.04_linux/bin:$PATH $ export JAVA_HOME=/usr/lib/jvm/java-6-oracle $ export PATH=$JAVA_HOME/bin:$PATH $ ./build.sh odroidxu3
Once you complete the long build process, the img files can be found in “out/target/product/odroidxu3/update” directory.
adb over TCP/IP (Ethernet port)
Installation
XU3/XU3-Lite
There are different instructions to install Linux kernel image for Android and Linux. Since Android loads both from a kernel partition, we have to use fastboot to install into the dedicated partition. Please refer the partition table from here. In contrast, Linux boots by the instructions described in boot.ini the 1st FAT partition.
This is the instruction to install kernel image, zImage-dtb, to the boot card.
- host
$ sudo fastboot flash kernel <path/of/your/zImage-dtb>
This is to install android platform files, system.img, userdata.img, cache.img.
- host
$ sudo fastboot flash system <path/of/your/system.img> $ sudo fastboot flash userdata <path/of/your/userdata.img> $ sudo fastboot flash cache <path/of/your/cache.img>
Use this command to initialize the FAT partition.
- host
$ sudo fatboot erase fat
XU4
How to write images without fastboot on ODROID-XU4(android)
You can not use fastboot on ODROID-XU4, because It doesn't have USB otg port.
First! setup adb connection or copy image to fat partition.
Push image to ext4 partition.
- host
$ adb push xxxx.img /sdcard/ $ adb reboot
Enter u-boot prompt with USB-UART kit connection.
