SUMMARY
The Artificial Intelligence expansion package contains AI frameworks to enable AI application examples that could be run on STM32MP1 hardware.
This package consists in a OpenEmbedded meta layer named meta-st-stm32mpu-ai to be added on top of the STM32MP1 Distribution Package. It brings a complete and coherent easy to build / install environment to take advantage of AI on STM32MP1 hardware.
1. Prerequisite[edit source]
Install the STM32MP1 Distribution Package, but do not initialize the OpenEmbedded environment before having installed the meta-st-stm32mpu-ai meta layer (see next chapter).
2. Installation of the meta layer[edit source]
- Clone following git repositories into <Distribution Package installation directory>/layers/meta-st
cd <Distribution Package installation directory>/layers/meta-st git clone https://gerrit.st.com/stm32mpuapp/meta/meta-st-stm32mpu-ai.git -b thud
- Setup the build environment
cd ../.. DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh
- Add the new layers
bitbake-layers add-layer ../layers/meta-st/meta-st-stm32mpu-ai
3. Build the software image[edit source]
- X-LINUX-AI-CV OpenSTLinux expansion package (AI Computer Vision software)
bitbake st-image-ai-cv
4. Flash the built image[edit source]
Follow this link to know how to flash the built image.
5. Launch the AI software[edit source]
- Power up the board
- The AI demo launcher should be displayed at the end of the boot sequence
5.1. The AI demo launcher[edit source]
The AI demo launcher is a derivative of the GTK Demo Launcher application.
It is written in python3[1] and uses GTK[2] to display the user interface.
It allow to easily launch AI application examples.
A single tap on the touch screen or a single click with a mouse connected to the board is sufficient to launch a AI application.
