We appreciate the writers/authors/editors for the ODROID Magazine first issue. We have sent the gifts for all the Magazine members today.
The list of items are ;
8GB eMMC Module Linux
5V2A Power Supply
USB-UART Module Kit
U3 IO Shield
We will send the gifts to two or three writers for the February Issue because of our limited budget.
Welcome Mauro to Korea.
He flew from Brazil to Korea. We all went to camping to see the snow that Mauro really wanted to see. We played several sports games on the snow. Mauro is especially good at table tennis. Even the weather was cold, the sports made him take off his jacket.
We all love you Mauro. See you next year in Brazil.
We have been shipped ODROIDs to 135 countries for the last one year. Thank you all ODROID users. Here is the full list of countries; If your country is not in the list, you are the first person having ODROID in your country;)

Introduction of ODROID-XU Lite @$139
ODROID-XU is Samsung Exynos-5410 Octa-core based single board computer for developers.
It has 4 big Cortex-A15 cores and 4 small Cortex-A7 cores. The clock frequency of big cores is 1.6Ghz.
The XU board was launched in August-2013 and used for various applications with outstanding performance and various peripherals.
Recently we got the 1.4Ghz version of Exynos-5410 with relatively much lower price.
So we announce the lower cost version of ODROID-XU for may cost sensitive projects.
The price of XU-Lite is only US$139 while XU is US$169.
Yes, it is $30 cheaper. All other features are exactly same only except the clock frequency of Cortex-A15.
Here is a comparison chart of performance. We measured the performance with the Antutu on Android platform.
The difference of the performance is around 8%.
Thanks for visiting us at ARM TechCon 2013.
Visitors could experience the amazing performance of ODROID-XU+E.
ODROID-XU+E is connected to WQXGA(2560 * 1600) monitor via DisplayPort.
The OS is Ubuntu13.10. Thanks Mauro for your sleepless work for it.
We had 6-8 task windows at the same time, Chrome browser, game, Arduino compiling, CPU usage monitor, Terminal window for kernel build, etc. It worked all perfect without any delay.
People could also develop Arduino control app on ODROID-XU+E.
We had another demo for OpenCL. Thanks Imagination Technologies for the demo apps. The realtime image processing via OpenCL saves around 20% of the total power consumption.
Special thanks to Rob,
Your speech at the show attracted people. You caught eyes of all the people at the exhibition. You might not be aware of, but there were hundreds of people focusing on you.
See you all next year.
We exhibit at the ARM TechCon 2013. http://www.armtechcon.com/
The Expo pass is free at site. If you are nearby, please stop at the expo. Let’s share the idea together for future ODROIDs.

22 years ago(26-Aug-1991), a young student in Finland announced Unix/Minix based Operating System.
Yes, it is Linux OS and his name is Linus Tovalds.
He released Kernel 3.11-rc7 today with the celebration of 22nd birthday of Linux.
We’ve just ported it to Exynos-5410 based ODROID-XU.
Here is the booting log.

UART/USB2.0/eMMC/Cortex-A15/DRAM/Ethernet are working now.
We need to port USB3.0, GPU and many other devices on the board.
You can download the full Kernel source code via this link.
We already informed the performance of ODROID-XU (Exynos-5410) as described in below link.
Those tests were performed in Linux/Ubuntu platform.
Many people are also asking us the performance in Android platform.
So we decided to compare the performance of XU with X2/U2(Exynos-4412 Prime).
We used the famouse Antutu benchmarking tool.
This is the test result of ODROID-X2 1.7Ghz default clock.
This is the test result of ODROID-X2 2.0Ghz over clock.
This is the test result of ODROID-XU 1.6Ghz default clock.
This is the test result of ODROID-XU 1.8Ghz over clock.
For easier comparison, I made simpler charts.
XU shows obviously much higher performance than X2.
XU vs X2 (Default clock)
XU vs X2 (Over clock)
Please note that above tests were done under Performance Governor mode instead of OnDemand Governor mode to show the maximum peformance.
ODROID-XU has 2 x SuperSpeed USB 3.0 interfaces and 4 x HighSpeed USB 2.0 interfaces.
I want to introduce the USB 3.0 feature in ODROID-XU.
There is a standard A-Type 3.0 host connector and a micro A-B OTG 3.0 connector on the board.
If you need additional USB 3.0 host of standard A-type connector,
you can use 2 x USB 3.0 ports simultaneously with a Micro A to Standard A cable.
This item is available in our e-store.
We performed a benchmarking test with our USB3.0 to SATA3 HDD/SSD interface kit.
This is the PCB of USB3.0 to SATA3 HDD/SSD interface kit.
Tested SSD is OCZ’s Vertex3 128GB SSD.
Test Root File System : Linaro Ubuntu with Linux Kernel 3.4.5
Read Test Command : dd if=./test of=/dev/null bs=1M count=1000 iflag=nocache oflag=nocache
Write Test Command : dd if=/dev/zero of=./test bs=1M count=1000 iflag=nocache oflag=nocache conv=fdatasync
Write Speed : 190 MB/S
Read Speed : 151 MB/S
We also made a same test with USB 2.0 port.
Wrtie Speed : 25.5 MB/S
Read Speed : 22.8 MB/S
The throughput of storage on USB 3.0 is about 7~8 times faster than USB 2.0 in the real world.
We also tested our USB 3.0 to Gigabit Ethernet adapter performance.

This iPerf test shows about 60MByte/sec transfer rate.
It is 5~6 times faster than the 10/100 Ethernet speed.
I think we can improve the device driver and get more speed up to 80~90MByte/sec.
Let’s enjoy the SuperSpeed USB 3.0 performance with our tiny ARM embedded platform.
|How Much Faster ?
The ODROID-XU is based on Samsung Exynos5 Octa processor
Every developer wants to know the performance of new platform. The Samsung Exynos5 Octa SoC is mighty competitive as shown by following initial benchmarks compared to a Calxeda quad-core Cortex-A9 SoC, the TI OMAP4460 dual-core A9 1.2GHz SoC, and an Intel Atom D525 1.8GHz dual-core CPU plus Hyper Threading.
The first tests were done with Ubuntu 13.04 Linaro(13.07) server version and Kernel 3.4.5 to feel the speed of ODROID-XU. We used the famous Phoronix test suit for benchmarking on Linux.
Let’s start the bench marking with NAS Parallel Benchmarks which were developed by NASA. The NAS Parallel Benchmarks (NPB) are a small set of programs designed to help evaluate the performance of parallel supercomputers. The benchmarks are derived from computational fluid dynamics (CFD) applications and consist of five kernels and three pseudo-applications in the original “pencil-and-paper” specification (NPB 1). The benchmark suite has been extended to include new benchmarks for unstructured adaptive mesh, parallel I/O, multi-zone applications, and computational grids.
Starting with the scientific NAS Parallel Benchmarks test cases, the ODROID-XU with its Exynos5 Octa totally slams all of the x86 and ARM comparison hardware. The Intel Atom D525 at 1.8GHz that is dual-core plus also has Hyper Threading was also beaten by the ARM Cortex A15 quad core.
The ODROID-XU system had greater performance of 7-Zip compression.
The x264 video encoding also was found best on the ARM Cortex A15 Quad. It is getting closed to a real time encoding system.
The Smallpt is a global illumination renderer. It is 99 lines of C++, is open source, and a famous benchmarking tool.
Less is better ! ODROID-XU is better.
The Samsung Exynos5 Octa performance is quite compelling. Being found in a $149 ODROID-XU that can be loaded with Android or Linux distributions is also a very attractive bargain.
For those looking to get into ARM Linux/Android development, the ODROID-XU will prove to be a world’s best performance.
We also want to introduce a real time energy monitoring feature.
When the system performance is increasing, the power consumption and heat are also increasing. So we need to find the best balanced points of performance vs. low-energy racing.
ODROID XU+E model has 4 separated current/voltage sensors between PMIC and SoC to collect the power consumption of A15 cores, A7 cores, GPU and DDR3-RAM in parallel to optimize system energy consumption.
The real time monitor window is always visible if you enable the option. The window is transparency and overlay display. It is showing the CPU/GPU DVFS data, temperature, CPU load, voltage, current, power and other valuable information for system developers.
If you are a professional developer, you must purchase ODROID-XU+E instead of ODROID-XU.
You will meet the easy way to create energy efficient OS and application software.
Enjoy this video how we can monitor the performance and the energy consumption.
