This article aims to give the following information:
- How to use the X-LINUX-QT Developer Package to build Qt applications for the STM32 microprocessor series.
1. Prerequisites
Check detailed prerequisites here.
2. Update the SDK environment for CMake
 Information
|
| The OE_CMAKE_TOOLCHAIN_FILE variable needs to be set to allow building CMake projects with the installed SDK |
Follow below steps if you need to add the missing OE_CMAKE_TOOLCHAIN_FILE variable to your SDK configuration
- Open terminal and load the environment setup
source /opt/st/stm32mp2/4.2.4-openstlinux-6.1-yocto-mickledore-mpu-v24.06.26/environment-setup-cortexa35-ostl-linux
- Export the OE_CMAKE_TOOLCHAIN_FILE variable
export OE_CMAKE_TOOLCHAIN_FILE="$OECORE_NATIVE_SYSROOT/usr/lib/cmake/Qt6/qt.toolchain.cmake"
3. Download the Demo example source code
mkdir -p /opt/st/demos/Qt cd /opt/st/demos/Qt git clone https://github.com/KDABLabs/KDBoatDemo.git -b qt6
4. Build the Demo example
cd KDBoatDemo
cmake -S . -B config_default

5. Deploy the Demo example to your running board
- Copy the Example's binary into your connected board
cd /opt/st/demos/Qt
scp config_default/KDABBoatDemo root@192.168.7.1:/home/root/.
6. Run the Demo example on your board
- Connect to your running board
ssh root@192.168.7.1
- Run the Demo's example (windowed mode)
./KDABBoatDemo
- Check the running Demo example on your board's display
- Run the Demo's example (Full screen mode)
./KDABBoatDemo --fullscreen
- Check the running Demo example on your board's display
