Guide for setting up SMT sdk with qt for compilations.
Follow it step by step.
- SDK instalation
- QT SDK instalation
- COMPILING QT5/6 APPLICATIONS
- Running applications inside the board
1. SDK instalation:
In this guide im installing latest version 6.1.0 stm32mp1 SDK.
For more specific board and SDK version visit: https://www.st.com/en/embedded-software/stm32mp1dev.html#get-software
Host:~/$ mkdir stmcomp
Host:~/$ cd Downloads
Host:~/Downloads$ tar xvf en.SDK-x86_64-stm32mp1-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11.tar.gz -C ~/stmcomp
Host:~/Downloads$ cd ~/stmcomp
Host:~/stmcomp$ chmod +x stm32mp1-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11/sdk/st-image-weston-openstlinux-weston-stm32mp1.rootfs-x86_64-toolchain-5.0.8-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11.sh
Run the instalation script
Host:~/stmcomp$ ./stm32mp1-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11/sdk/st-image-weston-openstlinux-weston-stm32mp1.rootfs-x86_64-toolchain-5.0.8-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11.sh -d /Developer-Package/SDK
A successful installation outputs the following log:
ST OpenSTLinux - Weston - (A Yocto Project Based Distro) SDK installer version 5.0.8-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11
===================================================================================================================================
You are about to install the SDK to "<working directory absolute path>/Developer-Package/SDK". Proceed [Y/n]?
Extracting
SDK..........................................................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
$ . <working directory absolute path>/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
SOURCE SDK:
Host:~/stmcomp$ source /Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
If all done correctly:
Host:~/stmcomp$ echo $ARCH
has to return
arm
Simple gcc compilations can be performed now
2. QT SDK instalation:
Download QT sdk at: https://www.st.com/en/embedded-software/x-linux-qt.html#get-software
Host:~/$ mkdir ~/stmcomp/QT
Host:~/$ cd Downloads
Host:~/Downloads$ tar xvf en.en.SDK-x86_64-stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06-x-linux-qt-v2.1.0.tar.gz -C ~/stmcomp/QT
Host:~/Downloads$ cd ~/stmcomp
Host:~/stmcomp$ chmod +x /QT/stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06-x-linux-qt-v2.1.0/sdk/st-image-qt-openstlinux-weston-stm32mp2.rootfs-x86_64-toolchain-5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06-addon-x-linux-qt-v2.1.0.sh
TO INSTALL QT SDK TOOLS FIRST THE PRIMARY SDK HAS TO BE SOURCED
Host:~/stmcomp$ source /Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
If all done correctly:
Host:~/stmcomp$ echo $ARCH
has to return
arm
Go to the absolute path to the directory in which is installed the developer package:
Host:~/stmcomp$ cd /Developer-Package/SDK
RUN QT SDK INSTALATION SCRIPT:
Host:~/stmcomp$ ~/stmcomp/QT/stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06-x-linux-qt-v2.1.0/sdk/st-image-qt-openstlinux-weston-stm32mp2.rootfs-x86_64-toolchain-5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06-addon-x-linux-qt-v2.1.0.sh
A successful installation outputs the following log:
===============================================================================================================================================
ST OpenSTLinux - Weston - (A Yocto Project Based Distro) SDK installer version 5.0.3-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06 - X-LINUX-QT version 2.1.0 SDK-Addon installer
===============================================================================================================================================
Extracting X-LINUX-QT-Addon SDK................................................................................................Done.
Setting it up... Done.
Do you want to configure the Qt Creator for this SDK [y/n]? n
Qt Creator configuration will be ignored.
X-LINUX-QT-Addon SDK has been successfully set up and is ready to be used.
To make sure qt is correctly installed:
Host:~/stm$ which qmake
/home/Host/stm/Developer-Package/SDK/sysroots/x86_64-ostl_sdk-linux/usr/bin/qmake
which qmake - has to return the absolute path of qmake that is in the SDK,
NOT /usr/bin/qmake
3. COMPILING QT5/6 APPLICATIONS
SOURCE THE SDK
Host:~/stmcomp$ source /Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
Export the OE_CMAKE_TOOLCHAIN_FILE variable
Host:~/stmcomp$ export OE_CMAKE_TOOLCHAIN_FILE="$OECORE_NATIVE_SYSROOT/usr/lib/cmake/Qt6/qt.toolchain.cmake"
Host:~/stmcomp$ mkdir projects
Host:~/stmcomp$ cd projects
EXAMPLE APPLICATION COMPILATION:
Host:~/stmcomp/projects$ git clone https://github.com/KDABLabs/KDBoatDemo.git -b qt6
Host:~/stmcomp/projects$ cd KDBoatDemo
Host:~/stmcomp/projects/KDBoatDemo$ cmake -S . -B config_default

Compilation is done, copy the binary to STM32MP board :
Host:~/stmcomp/projects/KDBoatDemo$ scp config_default/KDABBoatDemo root@192.168.0.1xx:/home/root/.
Running QT applications inside the board:
CURRENTLY X-LINUX-QT IN ONLY AVAILABLE ON ecosystem release v6.0.0, if guide below does not work that means the ecosystem is not correct.
Board configuration guide:
BOARD:~/$ date +%y%m%d -s "20250701"
BOARD:~/$ date +%T -s "00:00:00"
For STM32MP1 series’ boards:
with GPU support (STM32MP157F-DK2 Discovery kit More info green.png), add this Qt™ package Debian path:
BOARD:~/$ echo "deb http://extra.packages.openstlinux.st.com/QTMP1GPU/6.0 scarthgap main" > /etc/apt/sources.list.d/extra.qt.packages.openstlinux.st.com.list
without GPU support (STM32MP135F-DK Discovery kit More info green.png), add this Qt package Debian path:
BOARD:~/$ echo "deb http://extra.packages.openstlinux.st.com/QTMP1CPU/6.0 scarthgap main" > /etc/apt/sources.list.d/extra.qt.packages.openstlinux.st.com.list
Refresh the apt database and install qt package:
BOARD:~/$ apt-get update
BOARD:~/$ apt install -y packagegroup-x-linux-qt
BOARD:~/$ apt-get install -y demo-launcher
BOARD:~/$ systemctl restart weston-graphical-session.service
After the board reboots run the compiled example application
BOARD:~/$ chmod +x KDABBoatDemo
BOARD:~/$ ./KDABBoatDemo
