| * The '''STM32MPU distribution for Android™''' running on the Arm<sup>®</sup> Cortex<sup>®</sup>-A core. It includes:
| | |MPUs list=STM32MP15x |
| ** The '''OpenSTLinux BSP''' consisting of:
| | |MPUs checklist=STM32MP13x, STM32MP15x |
| *** The [[Boot_chain_overview|boot chain]] based on [[TF-A overview|TF-A]] and [[U-Boot overview|U-Boot]].
| | }}</noinclude> |
| *** 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.
| |
| ** '''Application frameworks''' composed of middleware components relying on the BSP and providing a set of APIs:
| |
| *** '''OP-TEE''' APIs to run '''Trusted Applications (TA)''' that allow manipulating secrets (information not visible from Linux<sup>®</sup> and from the STM32Cube MPU Package)
| |
| *** '''Android''' APIs to run '''Applications''' that typically interact with the user via a display or a touchscreen.
| |
| * The '''STM32Cube MPU Package''', running on the Arm<sup>®</sup> Cortex<sup>®</sup>-M. As for STM32 MCUs, it is based on HAL drivers and middleware components and completed with a [[Coprocessor_management_overview|coprocessor management]] module.<br />

| == Open Source Software (OSS) philosophy ==
| |
| The '''Open source software''' source code is released under a license in which the copyright holder grants users the rights to study, change and distribute the software to anyone and for any purpose<ref>https://en.wikipedia.org/wiki/Open-source_software</ref>.
| |
| <br />
| |
| STMicroelectronics maximizes the usage of open source software and contributes to open source software communities. 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 until it is merged in the targeted repository (see [[STM32MP1 Distribution Package for Android]]).
