• Pre-integrated into Linux distribution based on ST environment
• Include AI frameworks to execute Neural Network models
• Include AI model benchmark application tools for MPU
• Easy application prototyping using Python language and AI frameworks Python API
• C++ API for embedded high-performance applications
• Optimized open-source solutions provided with source codes that allow extensive code reuse and time savings

meta-st-x-linux-ai

X-LINUX-AI OpenEmbedded meta layer to be integrated into OpenSTLinux distribution. It contains recipes for AI frameworks, tools and application examples for STM32MPx series

Compatibility

The X-LINUX-AI OpenSTLinux Expansion Package v5.1.0 is compatible with the Yocto Project™ build system Mickledore. It is validated over the OpenSTLinux Distribution v5.1.0 on STM32MP25x and STM32MP1x series.

Versioning

Since its release v5.0.0, the major versioning of the X-LINUX-AI OpenSTLinux Expansion Package is aligned on the major versioning of the OpenSTLinux Distribution. This prevents painful backward compatibility attempts and makes dependencies straightforward. The X-LINUX-AI generic versioning vx.y.z is built as follows:

• x: major version matching the OpenSTLinux Distribution major version. Each new major version is incompatible with previous OpenSTLinux Distribution versions.
• y: minor version, which is changed when new functionalities are added to the X-LINUX-AI OpenSTLinux Expansion Package in a backward compatible manner.
• z: patch version to introduce bug fixes. A patch version is implemented in a backward compatible manner.
