STM32MPU_EmbSW_Overall_Offer Overview
STM32MPU Embedded Software distribution is a set of software components, system build and development tools created to ease the development to be done on top of STM32MPU devices.
STM32MPU Embedded Software distribution includes:
- A Linux® distribution, running on the Arm® Cortex®-A processor(s) : OpenSTLinux distribution
- A STM32Cube Package, running on the Arm® Cortex®-M processor : STM32Cube package
OpenSTLinux distribution is a Linux® distribution based on the OpenEmbedded build framework. It includes the following collection of software components.
- OpenSTLinux BSP (OP-TEE secure OS, boot chain and Linux kernel):
- The boot chain based on TF-A and U-Boot
- The OP-TEE secure OS running on the Cortex®-A in secure mode
- The Linux kernel running on the Cortex®-A in non-secure mode
- Application frameworks such as the following Linux application frameworks (non-exhaustive list):
- Wayland-Weston as a display/graphic framework
- Gstreamer as a multimedia framework
- Advanced Linux Sound Architecture (ALSA) libraries
STM32Cube™ is a comprehensive embedded software libraries and drivers, delivered for each STM32 series.
- The CMSIS modules (core and device) corresponding to the Arm® core implemented in this STM32 product
- The STM32 HAL-LL drivers : an abstraction drivers layer, the API ensuring maximized portability across the STM32 portfolio
- The BSP Drivers of each evaluation or demonstration board provided by this STM32 series
- A consistent set of middlewares components such as RTOS, OpenAMP, ...
- A full set of software projects (basic examples, applications or demonstrations) for each board provided by this STM32 series
Description
This repo is a simple Readme describing all STM32MPU related GitHub projects, the open source offer for the STM32 MPU products.
