2. X-LINUX-AI Software stack introduction[edit source]

X-LINUX-AI is an STM32 MPU OpenSTLinux Expansion Package that targets artificial intelligence for STM32MPx series devices.
It contains Linux AI frameworks, development tools, as well as application examples to get started with some basic AI use cases such as computer vision.
It is composed of an OpenEmbedded meta layer, named meta-st-stm32mpu-ai, to be added on top of the STM32MPx Distribution Package. It brings a complete and coherent easy-to-build / install environment to take advantage of AI on STM32MPx series devices.

3. Versioning[edit source]

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 generic versioning X-LINUX-AI 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.

4. X-LINUX-AI v5.0.0[edit source]
