This page is a candidate for renaming (move). The requested new name is: STM32MP1 Artificial Intelligence expansion packages . The supplied reason is: add a "s" to package(s) for article name coherency . -- vabriou. Wiki maintainers: remember to update the pages that link this page before renaming (moving) it.

SUMMARY
The Artificial Intelligence expansion package contains AI frameworks to enable AI application examples that could be run on STM32MP1 hardware.

STM32MPU Embedded Software Distribution Package with the OpenSTLinux AI Expansion Package

This package consists in an 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

Install the STM32MP1 Distribution Package, but do not initialize the OpenEmbedded environment (sourcing the envsetup.sh) before having installed the meta-st-stm32mpu-ai meta layer (see next chapter).

2. Installation of the meta layer

• Clone following git repositories into <Distribution Package installation directory>/layers/meta-st

 cd <Distribution Package installation directory>/layers/meta-st
 git clone https://github.com/kraj/meta-clang -b thud
 git clone https://github.com/STMicroelectronics/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 in that order

 bitbake-layers add-layer ../layers/meta-clang
 bitbake-layers add-layer ../layers/meta-st/meta-st-stm32mpu-ai

3. Build the software image

• X-LINUX-AI-CV OpenSTLinux expansion package (AI Computer Vision software)

 bitbake st-image-ai-cv

Information

Note that building the image could take a while.

4. Flash the built image

Follow this link to know how to flash the built image.

5. Launch the AI software

• Power up the board
• The AI demo launcher should be displayed at the end of the boot sequence

5.1. The AI demo launcher

The AI demo launcher is a derivative of the GTK Demo Launcher application.

It is written in python3 and uses GTK to display the user interface. It allows 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 the AI application.
