ODROID-XU is the world’s first big.LITTLE architecture based bare-board computer.

ODROID-XU+E model has the integrated power analysis tool. This package contains a special ODROID-XU board which has 4 current/voltage sensors to measure the power consumption of the Big A15 cores, Little A7 cores, GPUs and DRAMs individually. The professional developers can monitor CPU, GPU and DRAM power consumption via included on-board power measurement circuit. By using the integrated power analysis tool, developers will reduce the need for repeated trials when debugging for power consumption and get the opportunity to enhance and optimize the performance of their CPU/GPU compute applications, and therefore keeping power consumption as low as possible.

The Odroid-xu povides one 30-pin dual row expansion header “CON10” and one 40pin connector “CON15” with MIPI DSI for LCD. The location and pinout of these connectors is illustrated blew. All signals on expansion headers are 1.8V except PWRON signal.

CON10 - 2×15 pins

CON15 - 1×40 pins

On ODROID-XU is a DIP Switch (sw1) to select the booting Device.

Upon power on the board will search for the boot media. It will perform the following:

• 1) iROM (Code inside the SoC) will attempt to read the boot media at the first 512 bytes of it. On those first 512 bytes fwbl1 should exist.
• 2) fwbl1 will load bl2 (SPL) that is part of the U-boot.
• 3) bl2 will load U-boot.
• 4) U-Boot will do whats left, such as handle TrustZone, load kernel image if setted.

This blob is the first thing that CPU will call, we don't have much information on it since its provided by Samsung. Position on SD: 1

This is the SPL, part of the U-Boot, upon building U-Boot you'll have the mkspl program what will extract it from the u-boot.bin Position on SD: 31

This is the U-Boot itself built. For more information about U-Boot please check their website: http://www.denx.de/wiki/U-Boot Position on SD: 63

This is the blob done by Samsung/ARM to support Trustzone platform. Position on SD: 719

The default env provided in U-Boot will attempt the following:

• 1) Load boot.ini script from the first FAT type partition from the boot media.
• 2) Load kernel from its on media/ramdisk position (This is the Android Boot)

• Odroid-xu has Min 8Gbyte eMMC or MicroSD memory card for system area.
• FAT partition to calculate the remaining blocks to create the partition.

• You will have spl/smdk5410-spl.bin and u-boot.bin, if you build it.

• You need to sign the smdk5410-spl.bin with Hardkernel's private key to make it bootable.

• If you want to contribute your patch, apply it to our u-boot github admin. Or, contact “odroid.uboot@hardkernel.com”

• And we will publically release the signed bl2 image within 48 hours if there is any update.

• To flash the updated images on your MicroSD card, refer the scriptor file sd_fusing.sh in sd_fuse directory.

• To flash the updated images on your eMMC moduel, refer the scriptor file emmc_fastboot_fusing.sh in sd_fuse directory.

• For eMMC update, you need a fastboot driver and micro-USB cable.

Installing required packages (Ubuntu 12.04) Building on Ubuntu 12.04 is currently only experimentally supported and is not guaranteed to work on branches other than master.

$ sudo apt-get install git gnupg flex bison gperf build-essential \
  zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
  libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
  libgl1-mesa-dev g++-multilib mingw32 tofrodos \
  python-markdown libxml2-utils xsltproc zlib1g-dev:i386

$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

Installing the JDK The Oracle/Sun JDK is no longer in Ubuntu's main package repository. In order to download it, you need to add the appropriate repository and indicate to the system which JDK should be used.

If the JDK version is higher than 1.6.0_39, you may meet some compilation errors.

sudo add-apt-repository "deb http://ftp.debian.org/debian squeeze main contrib non-free"
sudo apt-get update
sudo apt-get install sun-java6-jdk

$ java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

Configuring USB Access Under GNU/linux systems (and specifically under Ubuntu systems), regular users can't directly access USB devices by default. The system needs to be configured to allow such access.

The recommended approach is to create a file /etc/udev/rules.d/51-android.rules (as the root user) and to copy the following lines in it. <username> must be replaced by the actual username of the user who is authorized to access the phones over USB.

SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", MODE="0666"

Build android

./build.sh odroidxu platform

[[[[[[[ OUTPUT FOLDER = /media/codewalker/SSD/adonis/odroidxu-img ]]]]]]]

ok success !!!

Write system.img

In the host PC.

#fastboot flash system out/target/product/odroidxu/system.img

Reboot system

In the host PC.

#fastboot reboot

Note : Ramdisk contents are merged into system.img to minimize the build steps. You can also easily modify the system configuration for example init.*.rd file.

So there is no Ramdisk parition in the storage media.

Linux ODROID-XU works as follow:

It must have at least two partitions.

First Partition must be a FAT32 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 ext2, however its strongly not recommended due to Windows Users lost the capability of changing boot.scrs

Partition 1:

• Kernel Image (zImage)
• boot.scr
• uInitrd (if applicable)

Partition 2:

• rootfs (a.k.a. File System)

• Ubuntu 13.04 Ubuntu 13.04 Forum Thread
• Debian Wheezy (can be upgraded to Jessie) Debian Wheezy Forum Thread
• Ubuntu 13.07 Server (Linaro's Version) Ubuntu Server Forum Thread

Note: More distributions such as Fedora/OpenSUSE to come

HDMI On Linux works via the Exynos5 Hardware Composer. It is available on our github. Its on tools/hardkernel of branch odroidxu-3.4.y

Installation of it for custom proposes is very simple.

1. sh autogen.sh
2. ./configure
3. make
4. make install

This will install the exynos5-hwcomposer that must he running in order to get X11/Xorg output.

Right now 720P 60Hz and 1080P 60Hz are the supported modes for the HDMI.

It is possible to change it on OFFICIAL images listed above by chaning the boot.scr file on the fat partition.

We current supply inside the FAT partition both boot.scr examples, just rename to what you plan to use.

Kernel sources for ODROID-XU is on our Github. Branch is odroidxu-3.4.y defconfig is odroidxu_ubuntu_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 0 https://github.com/hardkernel/linux.git -b odroidxu-3.4.y odroidxu-3.4.y
3. Configure Kernel: make odroidxu_ubuntu_defconfig
4. Do changes if you need/want: make menuconfig or make xconfig
5. Build Kernel and Modules: make -j5 zImage modules
6. Install zImage: cp arch/arm/boot/zImage /media/boot
7. Install Modules: make modules_install
8. Copy .config to /boot for initramfs creation: cp .config /boot/config-3.4.5
9. Create initramfs: update-initramfs -c -k 3.4.5
10. Create uInitrd: mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n uInitrd -d /boot/initrd.img-3.4.5 /boot/uInitrd-3.4.5
11. Install new uInitrd: cp /boot/uInitrd-3.4.5 /media/boot/uInitrd
12. 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 Simple Script.

wget builder.mdrjr.net/tools/kernel-update.sh
sh kernel-update.sh

Please make sure that you always download a new script before running it. Small fixes for the rootfs can be added to the script itself.
