How to install ExaGear Desktop Trial on Odroid

Posted on by neal.kim

Thank to Eltechs for the great instruction and giving ODROID users a trail. This article is written by Eltechs team.
Please share your experience on ODROID forum.

ExaGear Desktop is a powerful emulator for porting almost any x86 applications to ARM-based devices. In a nutshell, if you need some Windows apps or on your Odroid for any specific purpose (e.g. Notepad++ or even MS Word), ExaGear is the best solution to make it happen. Not mentioning the fact, that some native Linux applications, such as Skype and TeamViewer, when launched within ExaGear run even faster than launched via Wine on Linux. If you need more information visit our product page!

Install ExaGear Desktop Trial on Odroid
Our ExaGear Odroid Trial is kept on Odroid repos and is available for the following ODROID models:

ODROID-XU4 / XU3
ODROID-C2
ODROID-C1+ / C1
ODROID-U3 / U2 / X2 / X

Within the following OS images on:

Ubuntu 16.04
Debian Jessie
ODROID GameStation Turbo
DietPi

 

Within the following OS images on:
1. Connect a keyboard and a mouse to your Odroid device, or connect to it remotely – whatever you got used to.
2. Call for the command line and input the following commands to update the system.
 $ apt-get update
3. After a few minutes of auto-updating, you need to proceed with the following command:
 $ apt-get install exagear-desktop
4. As soon as the installation is finished, simply switch on the ExaGear software:
 $ exagear
5. The pop-up window will appear for you to provide your name and e-mail address. After you are done with that your ExaGear Odroid Trial will be activated and will last for 3 days from the moment of activation.

You might want to check if ExaGear is properly installed on you Odroid device. You can do it the following way:

 $ uname -a
You should get the output like:
Linux odroid 4.9.51-64 #1 SMP PREEMPT Sat Sep 23 03:28:28 UTC 2017 i686 i686 i686 GNU/Linux
6. Finally, we recommend to check that everything is OK by running the “arch” command (it should result in “i686” output):

$ arch
i686
 
 
Playing Windows Games on Odroid
Well, you are done with the installation and activation of your trial, so it’s the very time to enjoy the full power of ExaGear Desktop emulator by playing different famous Windows games on your Odroid device. Of course, gaming on Odroid is just a very small part of what ExaGear software can really do, but this user case is very representative and after all simply cool!
Tobias Schaaf from Odroid Magazine has prepared an outstanding article, covering some of the most popular PC games to be installed and played on Odroid, using ExaGear Desktop as an emulation machine and PlayOnLinux app. Read the ultimate tutorial here or watch a detailed video-guide below!

ODROID-HC1 Power consumption measurement

Posted on by neal.kim

We could assume the total cost of electricity bill using ODROID-HC1 : Home Cloud One Server 24hours/7days at home.

 

We installed the Ubuntu 16.04 minimal image(Kernel 4.9.44) and FTP, SAMBA, NFS, Plex-Media, Seafile, Serviio,
Transmission and WebDAV server applications were running in background.
It consumes 3.6Watt (average) when it is idle and the attached hard disk drive is in spin-down mode.

Here is the detail analysis of power consumption.
Booting : A peak pulse up to 5V/3A(~15Watt) when the HDD starts to run.
Idle, HDD is still spinning : Around 5-6Watt.
Transferring some big files with SAMBA via Gbit Ethernet interface : 7~9Watt approximately.
Idle, HDD spin-down : Average 3.6Watt.
We believe we can make it even lower if we tweak the CPU governor and scaling frequency options.

We’ve measured the power consumption of the ODROID-HC1 with SmartPower2.

[HOW-TO] Finding your ODROID IP Address – Headless

Posted on by neal.kim

Finding your ODROID’s IP Address from your laptop/desktop computer for remote access like SSH or VNC.

You can find your ODROID by doing what’s known as an “IP Scan” across your whole network. Most home networks will have about 254 possible combinations of IP address, so looking at them all is an easy task for a computer. I tried something called Angry IP Scanner ( http://angryip.org/ ), this runs on Linux, MacOS X or Windows and lets you scan your entire local network to find devices- including any ODROID’s you might be running. When you run Angry IP Scanner it should automatically pick a sensible IP Range for you. All you need to do is press [Start] and keep eyes out for your ODROID. It was much more comfortable than the nmap command for me.

As you can see above, Angry IP Scanner found my ODROID on the local network with its default hostname of “odroid.local” in official Ubuntu image.
Things to remember
1. Your ODROID may have a different IP address depending on whether it’s connected to WiFi or Ethernet, and that address might even change from time to time. If you ever find yourself unable to connect, you can always double-check!
2. Some other OS images might not have the Hostname. So you have to try to access the IP with SSH not to miss your ODROID.
3. If you don’t like the GUI IP scanner(Angry IP), you can use simpler “nmap” command. https://nmap.org/

Benchmark results for Raspberry Pi 3 Model B, ODROID-C1+, ODROID…

Posted on by neal.kim

We ran several benchmark tests to measure the computing power of the XU4. The same tests were performed on the Raspberry Pi 3 Model B, ODROID-C1+, ODROID-C2 and ODROID-XU4. The values of the test results were scaled uniformly for comparison purposes. The computing power of the XU4 was measured to be ~7 times faster than the latest Raspberry Pi 3 thanks to the 2Ghz Cortex-A15 octa-core and much higher 64bit memory bandwidth. Using the XU4 as a computer provides a “desktop like” experience, unlike the industry wide sluggish performance of most single-board computers! Particularly for developers, compiling code on the XU4 is super fast. The coveted high-performance 2GB DDR3 RAM is an additional advantage allowing most programs to be compiled directly on the XU4.

The most affordable high-performance DIY 8TB NAS

Posted on by neal.kim

A ODROID forum user @linuxest reported the most affordable 8TB external storage could work with XU4 UAS driver in Kernel 4.9.

I also wanted to make my own NAS because my Google Cloud storage was almost full.
I ordered the same storage(STEB8000100) from Amazon. It is US$180 only. 1TB costs $22 approximately.
https://www.amazon.com/Seagate-Expansion-Desktop-External-STEB8000100/dp/B01HAPGEIE

It has arrived here this morning and I have run a few samba performance test with kernel 4.9 on my xu4q. I formatted the storage with EXT4 file system before testing because its stock file system is NTFS.

Downloading an 8GB file to my laptop from the XU4 NAS. It shows 110MB/sec of transfer speed stably.

Uploading an 8GB file to the XU4 NAS from my Windows laptop. It shows 90~100MB/sec of transfer speed.

 

Helios LanTest (3GB transfer option) also shows good performance too.

How to Assemble !

XU4Q and the official case

Velcro tape (3M Scotch 40mm x 25mm 4-pairs)

Attach Velcro tape (loop side) to the XU4Q case bottom

Attach Velcro tape (hook side) to the Seagate HDD case

Place the XU4Q case on the HDD case

Connect cables.
DC plug for HDD, DC plug for XU4Q, Ethernet and USB 3.0 cables.

Rob Roy : Editor-In-Chief

“All of the contributors constantly amaze us with their innovations, and some of the highlights from the last two years include a soccer-playing robot, electronic grape synthesizer, a fully automated Pixar lamp with a sassy personality, a Wall-E clone, and an inexpensive yet powerful quad-copter drone. Our regular columnists like Tobias, Venkat and Nanik write fantastic in-depth tutorials and reviews that help our readers find new ways to work with and enjoy their ODROIDs. We always feature more than a few games in each issue as well, since ODROIDs can emulate so many different platforms. My favorites include the wonderful DOS-based games from our childhood, along with modern Android games like Clash of Clans, Beach Buggy Racing, Hearthstone and Five Nights at Freddy’s. We look forward to continuing to produce the best magazine that we can, and are expanding our staff this year with a few more assistant editors. I hope that the ODROID community continues to send us great and fascinating articles, since the community is what really makes our publication thrive.”

 

Bruno Doiche : Senior Art Editor

“ODROID Magazine is more than a project in that some months we toil hard. It is extremely humbling to work side by side with so many talented folks, and to see the power of a community that keeps building its knowledge using the ODROIDs for different reasons, such as gaming, server, hacking, and robotics. I think that we all have the brightest future ahead of us, and what is even better, having endless fun!”
Manuel Adamuz : Spanish Editor

“ODROID magazine is awesome. I have learned to do many things from reading it, such as flashing images, installing and updating the OS, installing and playing games and emulators, and much more. One thing that I love about ODROID magazine is that it has articles for all levels. No matter if you’re a beginner or an expert in Linux, It has something for everyone. I hope that people keep writing articles that are so good and extensive, although that means that I have more work as a Spanish translator 🙂 Happy anniversary!”
Nicole Scott : Art Editor

“Cheers to the third year ODROID Magazine! So much has happened in such a short time. I’m continually impressed with all the developments in ARM technology in both hardware and software. Working on the magazine is both fun and rewarding, as well as a great conversation starter. Having learned so much with each issue, I look forward to seeing what the ODROID inventors, developers, and computer science enthusiasts come up with next!”
James LeFevour : Art Editor

“It’s amazing how much expertise and geeky knowledge gets poured into this magazine every month. I am blown away by how much there is to learn about ODROIDs, and especially how much enthusiasm it promotes. I love being a part of this team!”

The nostalgic 20 year-old Macintosh analog amplifier meets 21st century audiophile.

The C1+ HiFi Shield is a high-resolution Digital to Analog Converter(DAC) for the ODROID-C1+. This is a special sound card for the C1+, that is optimized for the best fidelity audio playback quality. It delivers a nicely balanced sound, solid, deep, wide and nicely layered.We’ve analysed the the audio quality of the HiFi Shield DAC output with the famous industry standard equipment, Audio Precision. The Audio Precision is a high performance audio analyser optimized for the digital audio product.

The analog output of the HiFi Shield is connected to the equipment and measurement data shows on the host PC.
This picture shows a basic configuration of the set-up. Note that I disconnected the external amplifier when we measured the line-out audio quality.
The Signal to Noise Ratio (SNR)
The Noise Level in dBm
The Frequency Response and RMS output level in dBV
The Total Harmonic Distortion + Noise Ratio  (THD+N)
The FFT spectrum analyzer for 1Khz signal

This is a great idea if you want an audiophile set-up with ODROID-C1+. Enjoy a variable output connecting directly into a power amp or active speakers.

Good Bye ODROID-U3

Posted on by neal.kim

Exynos4412 platform has been the most loved products for the last 3 years. The ODROID-X was the first on 11th of July, 2012. And the family models of the ODROID-X2, U2 and U3 followed it. The ODROID-U3 was the latest model with Exynos4412 processor.

We have got the notice from Samsung that Exynos4412 will be discontinued soon. Because their SoC semiconductor production line is upgraded to the next generation like 28nm and 14nm. The Exynos4412 was made with the slightly old 32nm process. The more critical reason is that Samsung DRAM memory production has moved to the LP-DDR3/DDR4 technology while Exynos-4412 can use only the old LP-DDR2 memory which must to be pre-assembled on the SoC (Package-on-Package). So there is no way to keep buying the key component securely anymore to make the U3.

The ODROID-U3 was the most loved model by Hardkernel members. We have tried to keep this model even the price increases. The price of ODROID-U3 was $65.00 and we had to increase it to $69.00 this year due to material cost increase. But, we cannot make the ODROID-U3 even at higher price now.

We are really sorry that we couldn’t expect this situation earlier, and that caused any inconvenience who needs more U3 boards.

Now, the ODROID-XU4 will replace the position with the next generation processor, Exynos5422 Octa-core. The ODROID-XU4 has better performance and better connectivity with similar price range. We will make a long term plan with ODROID-XU4 supporting for a couple of years.

Thanks,

from Hardkernel members.
