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.

====== Expansion Boards and Accessories ======
----
====== Boot Loader======
----
===== Boot Media =====
On ODROID-XU is a DIP Switch (sw1) to select the booting Device.
* both eMMC5.0 and 4.4 booting mode of following table are whatever for eMMC booting.
\\
\\
\\
\\
\\
^ SW1-1,2 ^ 1st Boot media ^
| ON ON | eMMC5.0 |
| ON OFF | eMMC4.4 |
| OFF ON | MicroSD card |
| OFF OFF | Reserved |
===== Boot Sequence =====
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.
=== fwbl1 ===
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
=== bl2 ===
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
=== u-boot.bin ===
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
=== TrustZone Software ===
This is the blob done by Samsung/ARM to support Trustzone platform.
Position on SD: 719
=== Default Env ===
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)
===== Boot media sector map for Odroid-xu =====
* Odroid-xu has Min 8Gbyte eMMC or MicroSD memory card for system area.
* FAT partition to calculate the remaining blocks to create the partition.
^ Area Name ^ Size in bytes ^ From(sector #) ^ To(Sector #) ^ Partition Name ^
| FAT32 for Storage | Up to 4GB | 6979920 | remaining blocks | mmcblk0p1 |
| EXT4 for Android cache | 256MB | 6446520 | 6979919 | mmcblk0p4 |
| EXT4 for Android userdata | 2GB | 2240280 | 6446519 | mmcblk0p3 |
| EXT4 for Android system | 1GB | 137160 | 2240179 | mmcblk0p2 |
| Reserved | 58MB | 17647 | 137159 | |
| Kernel | 8MB | 1263 | 17646 | |
| u-boot environment | 16KB | 1231 | 1262 | |
| TrustZone SW | 256KB | 719 | 1230 | |
| u-boot | 328KB | 63 | 718 | |
| bl2 | 16KB | 31 | 62 | |
| fwbl1 | 15KB | 1 | 30 | |
| Partition table / MBR | 512 | 0 | 0 | |
* "Sector number - 1" in SD map is used in the eMMC map.

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 \

$ 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. 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"

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 ======
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 Contents ===
Partition 1:
* Kernel Image (zImage)
* boot.scr
* uInitrd (if applicable)
Partition 2:
* rootfs (a.k.a. File System)
=== Currently Supported Linux Distributions ===
* Ubuntu 13.04 [[http://forum.odroid.com/viewtopic.php?f=61&t=1983|Ubuntu 13.04 Forum Thread]]
* Debian Wheezy (can be upgraded to Jessie) [[http://forum.odroid.com/viewtopic.php?f=62&t=2070|Debian Wheezy Forum Thread]]
* Ubuntu 13.07 Server (Linaro's Version) [[http://forum.odroid.com/viewtopic.php?f=61&t=2069|Ubuntu Server Forum Thread]]
Note: More distributions such as Fedora/OpenSUSE to come
=== HDMI Support On Linux ===
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.
- sh autogen.sh
- ./configure
- make
- make install
This will install the exynos5-hwcomposer that must he running in order to get X11/Xorg output.
=== HDMI Resolution Change ===
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 ===
Kernel sources for ODROID-XU is on our [[http://github.com/hardkernel/linux|Github]].
Branch is **odroidxu-3.4.y**
defconfig is **odroidxu_ubuntu_defconfig**
=== Kernel Rebuild Guide ===
Please follow the instructions below to rebuild the Linux Kernel for ODROID.
Those instructions cover native build of the Kernel.
- Install dependencies: **apt-get install build-essential libqt4-dev libncurses5-dev git**
- Clone Repo: **git clone --depth 0 https://github.com/hardkernel/linux.git -b odroidxu-3.4.y odroidxu-3.4.y**
git clone --depth 0 https://github.com/hardkernel/linux.git -b odroidxu-3.4.y odroidxu-3.4.y
- Configure Kernel: **make odroidxu_ubuntu_defconfig**
- Do changes if you need/want: **make menuconfig** or **make xconfig**
- Build Kernel and Modules: **make -j5 zImage modules**
- Install zImage: **cp arch/arm/boot/zImage /media/boot**
- Install Modules: **make modules_install**
- Copy .config to /boot for initramfs creation: **cp .config /boot/config-3.4.5**
- Create initramfs: **update-initramfs -c -k 3.4.5**
- 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**
- Install new uInitrd: **cp /boot/uInitrd-3.4.5 /media/boot/uInitrd**
- 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.
