| − | The diagram below shows [[STM32MPU Embedded Software distribution]] main components:
| |
| − | * The '''OpenSTLinux distribution''', running on the Arm<sup>®</sup> Cortex<sup>®</sup>-A, including:
| |
| − | ** The '''OpenSTLinux BSP''' with:
| |
| − | *** The [[Boot_chain_overview|boot chain]] based on [[TF-A overview|TF-A]] and [[U-Boot overview|U-Boot]].
| |
| − | *** The [[OP-TEE overview|OP-TEE ]] secure OS running on the Arm<sup>®</sup> Cortex<sup>®</sup>-A in secure mode.
| |
| − | *** The '''Linux<sup>®</sup> kernel''' running on the Arm<sup>®</sup> Cortex<sup>®</sup>-A in non-secure mode.
| |
| − | ** The '''application frameworks''' are composed of middlewares relying on the BSP and providing API:
| |
| − | *** on the '''OP-TEE''' side to run '''Trusted Applications (TA)''' that allow to manipulate secrets (not visible from the Linux and STM32Cube MPU Package)
| |
| − | *** on the '''Linux''' side to run '''Applications''' that typically interact with the user via the display, the touchscreen, etc.
| |
| − | * The '''STM32Cube MPU Package''' is running on the Arm<sup>®</sup> Cortex<sup>®</sup>-M: it is based on HAL drivers and middlewares, like other STM32 microcontrollers, completed with [[Coprocessor_management_overview|coprocessor management]].<br />

| − | STMicroelectronics maximizes the using of open source software and contributes to those communities. Notice that, due to the software review life cycle, it can take some time before getting all developments accepted in the communities, so STMicroelectronics can also temporarily provide some source code on github<ref>[[STM32MP1 Distribution Package]]</ref>, until it is merged in the targeted repository.
