2. X-LINUX-QT Expansion Package description[edit | edit source]
2.1. Overview[edit | edit source]
X-LINUX-QT is an STM32 MPU OpenSTLinux Expansion Package that targets Qt™ based application and graphical user interface (GUI) development for STM32MP25x lines 
.
It contains Linux® Qt™ frameworks, as well as an ST Application Launcher based on Qt™ Framework and application examples to get started with Qt™ application development.
The Qt™ framework contains a comprehensive set of highly intuitive and modularized C++ library classes and is loaded with APIs to simplify your application development. Qt™ produces highly readable, easily maintainable and reusable code with high runtime performance and small footprint – and it's cross-platform.
This expansion package is a complete ecosystem that allows developers working with OpenSTLinux to create Qt™ based application very easily.
- All-in-one Qt™ solutions for the STM32MP2 series supporting Wayland and Weston.
- Pre-integrated into Linux® distribution based on ST environment
- Include Qt™ frameworks to build UIs and Applications
- Include ST Application Launcher based on Qt™ framework forSTM32 MPU devices (see supported platforms list)
2.2. Main restrictions[edit | edit source]
This first version of X-LINUX-QT Expansion Package is not yet functional with STM32MP1 series.
2.3. Versioning[edit | edit source]
Latest version of X-LINUX-QT is 2.0.0.
The X-LINUX-QT Expansion Package is based to be used with OpenSTLinux distribution ecosystem release v5.1.0 
.
The generic versioning X-LINUX-QT vx.y.z is built as follows:
- x: major version depending on Qt™ major versions. Each new major version is incompatible with previous Qt™ versions. Initial major version 1.0.0 is for Qt 5.x and current version 2.0.0 is for Qt 6.x
- y: minor version depending on the OpenSTLinux distribution major versions. Each new major version is incompatible with previous OpenSTLinux distribution versions. Initial minor version will be for OpenSTLinux Distribution v5.x
- z: patch version is changed when new functionalities, bug fixes and/or modules are added to the X-LINUX-QT Expansion Package in a backward compatible manner.

6. Software setup[edit | edit source]
6.1. How to get software[edit | edit source]
There are 3 possibilities to install the additional X-LINUX-QT Expansion Package software to port on top of OpenSTLinux.
Select the one corresponding to your needs amongst :
- X-LINUX-QT Starter Package : quickly and easily bring Qt™ framework on STM32 MPU as graphics solution.
- X-LINUX-QT Developer Package: quickly and easily bring and develop with Qt™ framework on STM32 MPU as graphics solution.
- X-LINUX-QT Distribution package: an OpenEmbedded meta-layer must be added on top of the STM32MPU Distribution Package to bring "Qt™ framework" as graphics solution.
6.1.1. How to install the Starter Package[edit | edit source]
6.1.1.1. Install OpenSTLinux Starter Package[edit | edit source]
Before developing with the Developer Package, it is essential to start up your board thanks to its Starter Package. All articles relative to Starter Packages are found in Category:Starter Package: find the one that corresponds to your board, and follow the installation instructions (if not yet done), before going further.
Thanks to the Starter Package, all Flash partitions are populated.
6.1.1.2. Install the X-LINUX-QT Starter Package[edit | edit source]
The packagegroup-x-linux-qt package must be installed on top of the STM32MPU Starter Package to bring the "Qt framework" as graphics solution.
Once the board is booted, make sure it is connected to the internet then execute the following commands in the console to install the X-LINUX-QT packages:
- First of all , you may need to update date and time on your connected board before running the below commands. Date and Time on your connected board can be updated by this command:
date +%y%m%d -s "20250101" date +%T -s "00:00:00"
- Refresh the apt database to access the Qt™ package repository:
apt-get update
 Information
|
| If some proxy issue occurs executing the previous command, refer to prerequisites from here |
.
- Install the package with the apt configuration to access the Qt™ packages :
For Qt6: apt-get install apt-openstlinux-x-linux-qt_2.0
For Qt5: apt-get install apt-openstlinux-qt
- Update the apt database to read the Qt™ package repository :
apt-get update
- Install the package group for the X-LINUX-QT package
apt-get install -y packagegroup-x-linux-qt
- Restart the Weston graphical services with the new ST-Launcher
systemctl restart weston-graphical-session.service
| Information
|
| Instead of restarting the Weston graphical service which could take few seconds, user could just close the current GTK demo-launcher and start the new ST-Launcher from the weston bottom toolbar (last icon in the list) |
6.1.1.3. Starter Package expected results[edit | edit source]
Once the X-LINUX-QT Starter Package is installed and the Weston graphical service is restarted, the new STLauncher is displayed.
- The STLauncher Splash Screen is displayed for few seconds
- The Main Window displays all compatible installed applications
- To display more information about the running hardware and software:
- Click on the Settings button on the top right of the screen
- The SETTINGS screen is displayed
- Click on the INFORMATIONS button
- The INFORMATIONS screen is displayed
6.1.1.4. Run examples from the starter package[edit | edit source]
