Visual Studio Code on XU4 Ubuntu 18.04

When I was a student around 25 years ago, I had to spend over $200 to buy a Microsoft Visual Studio C++ software package.
At that time, I used Windows 3.1 on a blazing fast Intel 80286 8Mhz 16bit processor with 1MB RAM to build a small commercial software as a part-time job.

Today, we can run the Visual Studio on the XU4 Ubuntu Linux.
Visual Studio Code is a source code editor developed by Microsoft for Windows, Linux and macOS.
It includes support for debugging, embedded Git control, syntax highlighting, intelligent code completion, snippets, and code refactoring.
It is also customizable, so users can change the editor’s theme, keyboard shortcuts, and preferences.
It is free and open-source, although the official download is under a proprietary license.

From the VS Code GitHub :
You need following items.
– Git
– Node.JS, >= 8.9.1, < 9.0.0
– Yarn >= 1.5.0
– Python, >=  2.7 (version 3 is not supported)
– npm
– libx11-dev and libxkbfile-dev for native-keymap
– libsecret-1-dev for keytar

Let’s install the required packages.

sudo apt install git nodejs libx11-dev libxkbfile-dev libsecret-1-dev npm 

And check the versions of key components.

odroid@odroid:~$ yarn --version
odroid@odroid:~$ python --version
Python 2.7.15rc1
odroid@odroid:~$ nodejs --version
odroid@odroid:~$ npm --version

“yarn” command in “cmdtest” package was too old which was compatible with npm.
So you have to install “yarn” package manually.

curl -sS | sudo apt-key add - echo "deb stable main" | sudo tee /etc/apt
sudo apt update
sudo apt install yarn

And I had the latest “yarn” version.

odroid@odroid:~$ yarn --version

Let’s download Visual Studio Code source from MS Github and build it.

git clone --depth 1
cd vscode
./scripts/ install --arch=armhf

Then, run your instance with ./scripts/ from that same folder.
You must force to reinstal libgconf2 manually to fix a runtime error.

sudo apt -y install libgconf2-4

The first launching took quite a long time. Be patient.
The performance of source code editor was very good and look-and-feel was very similar to the original Visual Studio.
It’s time to learn how to configure the gcc and gdb command in the integrated development environment.

PUBG on ODROID-XU4 and how to play with keyboard/mouse

PlayerUnknown’s Battlegrounds is a multiplayer online battle royale game developed and published by PUBG Corporation, a subsidiary of publisher Bluehole. The last person or team left alive wins the match.

Thanks to Unreal Engine 4, mobile version was released for Android devices on February 9, 2018.

This guide shows the configuration for Android OS on ODROID-XU4. In detail, it includes how to control with keyboard and mouse. Everything to be the kings of the stage and eat the chicken.

Let’s check the hardware compatibility with PUBG on Android.

The company responsible for PUBG MOBILE has made a smart move using Unreal Engine 4 (UE4) for all versions of their games, they can apply the same content to all our platforms and continue with the same play experience on any devices.
The minimum requirements of the games are imposed by the UE4. This type of games can only be compiled with a profile that supports these features;
– Have a GPU with OpenGL support ES 3.1 or higher
– System with at least 2 GB of RAM
– Android 5.1.1
– Minimum free storage 2 GB
– Requires mouse or pointer emulator to select menus
ODROID-XU4 Android 7.1 (LineageOS port) meets the requirements. GPU on ODROID-XU4 supports OpenGL-ES 3.1, 2GB of RAM is stacked on the CPU, storage is expandable and USB ports are good enough for mouse.
Once you successfully install the Android 7.1 Nougat LineageOS-14.1, you can easily install the PUBG MOBILE from Google Play store.

Before playing PUBG, you have to tweak the Android performance mode for smoother game rendering speed.
Set CPU and DRAM governor to “Performance” mode, and overclock the DRAM speed slightly (866Mhz to 933Mhz).
It can be done with ODROID Utility App. After setting, you have to reboot ODROID.

Keyboard and mouse in PUBG MOBILE
If we want to be the kings of the game, certainly the use of keyboard and mouse in PUBG MOBILE will give us a substantial advantage, the ability to perform strafe (lateral movement), point with the mouse and manage all the functions of the game with the keyboard is a differential point, something that can be seen playing where our opponents with touch controls are very limited in movements.  None of these methods is officially supported by the game but we have a very simple alternative.

Install Octopus to play with keyboard and mouse in PUBG MOBILE, this app already comes with profiles for these controls for the game by default with what not we will have to configure anything.
Octopus app is available in Google Play too.
Run Octopus and as we see in the upper part we have the types of control that we have connected to our ODROID, we can use them all indifferently. In the lower part we have the list of installed games, by default we will start PUBG MOBILE, although we can use this program for other games.
Inside game the use is simple, we have defined by default the keys in the action areas so it is very simple, we can move them or change them as we are interested. On the left we have the Octopus icon that we can press to show the advanced options and change drivers, in ODROID we need a connected mouse.
Within the Octopus settings menu we can switch between Keyboard and Gamepad, we can see the two systems already have a template configured, in the case of the Gamepad we have few buttons available for all the actions that a game like PUBG has. But we didn’t try a Gamepad yet.
An important point in this app are the settings, the level of transparency of the keys on the screen can be lowered when we already have them memorized to have the cleanest screen, the POV Sensivility level is critical to control the character’s rotation speed which by default is somewhat slow.

Don’t forget to allow a root access to the Octopus app for activating the functionality.

Once you launch PUBG game via Octopus app, you need to check the Graphics settings. It must be something like this.

It was quite playable with $59 ODROID-XU4 board even we met short period of choppy scenes randomly.


Mali GPU accelerated Qt5 on Ubuntu 18.04

Ubuntu 18.04 Bionic comes with Qt 5.9.5 by default.
But, Canonical has built it without considering the ARM Mali GPU detection and Qt5 didn’t work on Ubuntu 18.04 at all.
So we have to build the Qt5 source code manually.

Here is a quick and dirty build guide. I tested on the latest XU4 Ubuntu 18.04 Bionic image.
sudo apt update && sudo apt upgrade && sudo apt dist-upgrade
Install build-depends and source code.
sudo apt build-dep qt5-default
apt source qtbase5-dev
cd qtbase-opensource-src-5.9.5+dfsg
Edit a file for correct detecting the ARM’s Mali GPU.
Line 86 : src/platformsupport/eglconvenience/qxlibeglintegration.cpp
to : if (vendor && (strstr(vendor, "Vivante") || strstr(vendor, "ARM"))) {
from : if (vendor && strstr(vendor, "Vivante")) {
Another file should be edited to avoid a compile error. I wasted several hours to find this simple solution.
Create two symlinks for proper OpenGL-ES detection. This fix will be included in the next update probably.
sudo rm /usr/lib/arm-linux-gnueabihf/
sudo rm /usr/lib/arm-linux-gnueabihf/
sudo ln -s /usr/lib/arm-linux-gnueabihf/mali-egl/ /usr/lib/arm-linux-gnueabihf/
sudo ln -s /usr/lib/arm-linux-gnueabihf/mali-egl/ /usr/lib/arm-linux-gnueabihf/
Build Qt5
sudo dpkg-buildpackage -b
I met this error when I ran it on a SSH session.
Project ERROR: QtDBus is enabled but session bus is not available. Please check the installation.
When I built it on the Mate desktop terminal instead of the remote ssh access, the build had no issue. It is still not understandable.After 2~3 hours of boring build time, the “debian packaging” failed due to a missing PGP key.
But all the Qt5 libraries with examples were generated correctly and I could install them with sudo make install command.Qt-OpenGL example works beautifully now.


We will test the stability and functionality for a couple of weeks.
If there is no critical issue, we will release it officially.
Feel free to post your idea on the forum thread.

SuperTuxKart on ODROID-XU4

Karts. Nitro. Action! SuperTuxKart(STK) is a 3D open-source arcade racer with a variety characters, tracks, and modes to play.
SuperTuxKart is a free kart racing game. It focuses on fun and not on realistic kart physics.

Recently, STK developers updated their source code to support the OpenGL-ES 3.x and we can play the nice game on the ODROID-XU4 natively.

Let’s try to compile the source code and build it! This instruction was tested on the official Ubuntu 16.04 image version 20171212.
If you are an OGST image user, simply install it with “apt-get install supertuxkart-odroid”.

1. Install required packages to build the source code.

sudo apt install git build-essential cmake libbluetooth-dev libcurl4-gnutls-dev libfreetype6-dev libfribidi-dev libgl1-mesa-dev libjpeg-dev libogg-dev libopenal-dev libpng-dev libvorbis-dev libxrandr-dev mesa-common-dev pkg-config zlib1g-dev libtool subversion

2. Download the latest STK source code from the official Github.

git clone stk-code

You have to download the game assets too from SVN. It took quite long time.

svn co stk-assets

3. Apply a patch to fix the color depth issue and OpenGL ES 3.x support.

cd stk-code
wget -O supertuxkart.patch
patch -p0 < supertuxkart.patch

The patch was made by @AreaScout forum member.

4. Compiling

mkdir cmake_build
cd cmake_build
cmake .. -DUSE_GLES2=1
make -j8

Compiling took around 30 minutes.

5. Test and install
Run the game with this command since 720p mode shows much better performance than 1080p.

DISPLAY=:0.0 ./bin/supertuxkart --screensize=1280x720 --fullscreen

You can install your build system-wide:

sudo make install

OpenGL ES 3.x shows more detail and beautiful 3D rendering than 2.0. Look at the racing circuit floor.

OpenGL ES3.x

OpenGL ES2.0

How to control ODROID-XU4 Cooling fan

ODROID-XU4 CPU has four 2Ghz big cores and four 1.4Ghz LITTLE cores.

It also has six GPU cores as well as 2GByte DRAM on the SoC with a package on package(PoP) process.

So this tiny SoC power consumption can be up to 10 Watt and it generates a lot of heat.
Therefore, we had to attach a cooling fan to the SoC to minimize the thermal throttling.
Once the system boots, the cooling fan runs at full speed by the u-boot(bootloader) initialization code.
When the Linux Kernel runs, the thermal management driver controls the fan speed automatically.
There are three threshold points 60°C, 70°C and 80°C.

Trip point 0 1 2
Temperature 60°C 70°C 80°C
Fan speed 120 180 240

The fan speed value is connected to 8bit(0~255) PWM control register.

When the SoC temperature is lower than 60°C, the fan doesn’t rotate.

If you need to adjust the temperature threshold values, just modify the thermal control nodes in sysfs.

For example, if you want to set trip point 1 to be activated at 30°C, you can just write a value on them.

$ echo 30000 | sudo tee /sys/devices/virtual/thermal/thermal_zone{0,1,2,3}/trip_point_0_temp
$ cat /sys/devices/virtual/thermal/thermal_zone{0,1,2,3}/trip_point_0_temp
# results

Then the fan starts spinning at 30°C.

If you want to do that automatically, write some code in the /etc/rc.local file.
Copy the following codes and paste.

# Target temperature: 30°C, 50°C, 70°C

echo $TRIP_POINT_0 > /sys/devices/virtual/thermal/thermal_zone0/trip_point_0_temp
echo $TRIP_POINT_0 > /sys/devices/virtual/thermal/thermal_zone1/trip_point_0_temp
echo $TRIP_POINT_0 > /sys/devices/virtual/thermal/thermal_zone2/trip_point_0_temp
echo $TRIP_POINT_0 > /sys/devices/virtual/thermal/thermal_zone3/trip_point_0_temp

echo $TRIP_POINT_1 > /sys/devices/virtual/thermal/thermal_zone0/trip_point_1_temp
echo $TRIP_POINT_1 > /sys/devices/virtual/thermal/thermal_zone1/trip_point_1_temp
echo $TRIP_POINT_1 > /sys/devices/virtual/thermal/thermal_zone2/trip_point_1_temp
echo $TRIP_POINT_1 > /sys/devices/virtual/thermal/thermal_zone3/trip_point_1_temp

echo $TRIP_POINT_2 > /sys/devices/virtual/thermal/thermal_zone0/trip_point_2_temp
echo $TRIP_POINT_2 > /sys/devices/virtual/thermal/thermal_zone1/trip_point_2_temp
echo $TRIP_POINT_2 > /sys/devices/virtual/thermal/thermal_zone2/trip_point_2_temp
echo $TRIP_POINT_2 > /sys/devices/virtual/thermal/thermal_zone3/trip_point_2_temp

Reboot and check if the changes applied well or not.

If you want to change the fan speed values in trip points, modify this system node.


You can check current fan speed scaling.

$ cat /sys/devices/platform/pwm-fan/hwmon/hwmon0/fan_speed
# results
0 120 180 240

You can adjust these values by writing value set to the file.
If you want to make your fan more aggressively, you can write like below.

$ echo "0 204 220 240" | sudo tee /sys/devices/platform/pwm-fan/hwmon/hwmon0/fan_speed
# results
0 204 220 240

If you want to do that automatically, write some code in the /etc/rc.local file.
Copy the following codes and paste.

# Target fan speed (PWM): 0, 204, 220, 240
echo "0 204 220 240" > /sys/devices/platform/pwm-fan/hwmon/hwmon0/fan_speed

You can also control the fan speed fully manually.

# Set fan to manual mode
$ echo 0 | sudo tee /sys/devices/platform/pwm-fan/hwmon/hwmon0/automatic
# Set speed to 100%
$ echo 255 | sudo tee /sys/devices/platform/pwm-fan/hwmon/hwmon0/pwm1

– Kodi 17.6 (1080p video playback issue fixed)
– GPU/WebGL acceleration is enabled in Chromium browser
– CPU performance-counter feature works with big and little cores
– Removed broken Firefox
– Fixed mouse cursor blink issue

With each Linux kernel development cycle, it is getting easier to get updates to the latest mainline kernel due to the efforts of Samsung and the community. Some device drivers are added in the kernel which is not included in the mainline version.

Long Term Support (LTS) kernel support will get support until Jan, 2020. This is great news for the owners of small, extensible, powerful and inexpensive boards such as the ODROIDs.

Download it from this link.

You can upgrade from 4.9 to 4.14 with following commands. You need to backup your important data first.

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt install xserver-xorg-video-armsoc ffmpeg
sudo apt install linux-image-xu3 
sudo reboot

When you install “linux-image-xu3” package, you will meet a dialogue box and you have to choose “No” to proceed Kernel update.

After update, you can check Kernel version.

odroid@odroid:~$ uname -a
Linux odroid 4.14.0-83 #1 SMP PREEMPT Thu Nov 23 14:07:46 UTC 2017 armv7l armv7l armv7l GNU/Linux

Please note that we will no longer support Kernel 4.9 due to our limited resources. We will keep updating Kernel 4.14 LTS only.

If you have any issues, please post it on the Kernel 4.14 development sub-forum.

How to install ExaGear Desktop Trial on Odroid

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-U3 / U2 / X2 / X

Within the following OS images on:

Ubuntu 16.04
Debian Jessie
ODROID GameStation Turbo


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:

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

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.
