How to install X-LINUX-AI v2.0.0 on Avenger96 board

This article explains how to use and rebuild X-LINUX-AI v2.0.0 on an OpenSTLinux v1.2.0 distribution using the Avenger96 board.

For more detailed information about X-LINUX-AI Expansion Package, refer to X-LINUX-AI OpenSTLinux Expansion Package.

Information

The OpenSTLinux v2.0.0 is not yet supported on the Avenger96 board.

1. Validated hardware

As any software expansion package, X-LINUX-AI is supported on all STM32MP1 Series. It has been validated on the following boards:

• STM32MP157 Avenger96 board + an UVC USB WebCam or the OV5640 CSI Camera mezzanine board

Optional:

• Coral USB Edge TPU accelerator

2. Re-generating X-LINUX-AI OpenSTLinux distribution

Use the following procedure to re-generate the complete distribution and enable the X-LINUX-AI expansion package.
This procedure is mandatory if you need to update by yourself some frameworks or modify the application samples.

2.1. Downloading the STM32MP1 Distribution Package v1.2.0

Install the STM32MP1 Distribution Package v1.2.0, but do not initialize the OpenEmbedded environment (do not source the envsetup.sh).

2.1.1. Cloning the meta-av96 and meta-st-stm32mpu-ai git repositories

Warning

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.

 cd <Distribution Package installation directory>/layers
 git clone https://github.com/vinceab/meta-av96.git -b av96_v50
 cd <Distribution Package installation directory>/layers/meta-st
 git clone https://github.com/STMicroelectronics/meta-st-stm32mpu-ai.git -b v2.0.0_thud

2.2. Setting up the build environment

 cd ../..
 META_LAYER_ROOT=layers DISTRO=openstlinux-weston MACHINE=stm32mp1-av96 source layers/meta-st/scripts/envsetup.sh

2.3. Adding the new layers to the build system (in that order)

 bitbake-layers add-layer ../layers/meta-av96
 bitbake-layers add-layer ../layers/meta-st/meta-st-stm32mpu-ai

2.4. Building the image

 bitbake st-image-ai

Information

Building the image can take a long time since it depends on the host computer performance.

2.5. Flashing the built image

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