X-LINUX-AI OpenSTLinux Expansion Package

(Redirected from How to install X-LINUX-AI v2.0.0 on OpenSTLinux v1.2.0)
AI Expansion Package inserted in the STM32MPU Embedded software distribution

X-LINUX-AI is an STM32 MPU OpenSTLinux Expansion Package that targets artificial intelligence for STM32MP1 Series devices.

It contains Linux AI frameworks, as well as application examples to get started with some basic use cases such as computer vision (CV).

It is composed of 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 Series devices.

2 Install from the OpenSTLinux AI package repository[edit]

Info.png The STMicroelectronics packages repository service is provided for evaluation purposes only, its content may be updated at any time without notice and is therefore not approved for use in production.

All the generated X-LINUX-AI packages are available from the OpenSTLinux AI package repository service hosted at the non-browsable URL http://extra.packages.openstlinux.st.com/AI.

This repository contains AI packages that can be simply installed using apt-* utilities, which the same as those used on a Debian system:

  • the main group contains the selection of AI packages whose installation is automatically tested by STMicroelectronics
  • the updates group is reserved for future uses such as package revision update.

You can install them individually or by package group.

2.1 Prerequisites[edit]

ST boards prerequisites:

  • Flash the Starter Package on your SDCard
STM32MP157x-DKx Starter Package procedure
or
STM32MP157x-EV1 Starter Package procedure
  • Your board has an internet connection either through the network cable or through a WiFi connection.
Info.png

If your internet access depends on a proxy server, you should define the http_proxy environment variable with the following command before any apt-* commands:

Board $> export http_proxy='http://<proxy url>:<proxy port>/'

Avenger96 board prerequisites:

  • The Avenger96 board starter image supporting OpenSTLinux v2.1.0 must be flashed on to your SD Card
OpenSTLinux-2.1 based on Yocto Dunfell LTS and Linux 5.4.56 - v6.5 Starter Image
  • Your board has an internet connection either through the network cable or through a WiFi connection.

4 How to use the X-LINUX-AI Expansion Package[edit]

4.1 Material needed[edit]

To use the X-LINUX-AI OpenSTLinux Expansion Package, choose one of the following materials:

  • STM32MP157C-DK2[8] + an UVC USB WebCam
  • STM32MP157C-EV1[9] with the built in OV5640 parallel camera
  • STM32MP157A-EV1[10] with the built in OV5640 parallel camera
  • STM32MP157 Avenger96 board[1] + an UVC USB WebCam or the OV5640 CSI Camera mezzanine board[11]

Optional:

  • Coral USB Edge TPU[2] accelerator

4.2 Boot the OpenSTlinux Starter Package[edit]

At the end of the boot sequence, the demo launcher application appears on the screen.

4.3 Install the X-LINUX-AI[edit]

Warning.png The software package is provided AS IS, and by downloading it, you agree to be bound to the terms of the software license agreement (SLA). The detailed content licenses can be found here.

After having configured the AI OpenSTLinux package you can install the X-LINUX-AI components.

Board $> apt-get install packagegroup-x-linux-ai

And restart the demo launcher

Board $> systemctl restart weston@root

4.4 Launch an AI application sample[edit]

Once the demo launcher is restarted, notice that it is slightly different because new AI application samples have been installed.
The demo laucher has the following appearance, and you can navigate into the different screens by using the NEXT or BACK buttons.

Demo launcher appearance when X-LINUX-AI is installed

Screens 2, 3 and 4 contain AI application samples that are described within dedicated article available in the X-LINUX-AI application samples zoo page.

4.5 Enjoy running your own NN models[edit]

The above examples provide application samples to demonstrate how to execute models easily on the STM32MP1.

You are free to update the C/C++ application or Python scripts for your own purposes, using your own NN models.

Source code locations are provided in application sample pages.
