As a mainlined open-source Linux distribution, OpenSTLinux Distribution is a key element of the STM32 Embedded Software solution for STMicroelectronics’ STM32 multi-market, multi-core microprocessors (MPU) embedding a single or dual Arm Cortex-A7 core.
Developers should note that OpenSTLinux Distribution is not a specific, custom Linux distribution. By investing heavily in mainlining the OpenSTLinux Distribution, ST is demonstrating its dedication to accelerating the development of systems that needs high processing power and graphical support combined with power-efficient real-time control and high feature integration and providing developers with an unprecedented level of support.
Designers working on a wide range of applications including industrial, consumer, medical and smart home can benefit from seamless software migration during kernel upgrades, improved software quality and robustness as well as reduced risk, together with development resources allocated to new innovative functionalities at the application level.
The OpenSTLinux Distribution contains:
• Linux board support package (BSP).
• Linux kernel.
• Required drivers.
• Secure bootchain based on Arm Trusted Firmware (TF-A) and Universal Boot Loader (U-Boot).
• Secure OS: Open Portable Trusted Execution Environment (OP-TEE).
• Application frameworks including Wayland display server protocol (Weston reference implementation), Gstreamer multimedia framework and Advanced Linux Sound Architecture (ALSA) libraries.
To optimise each development phase of a project, ST offers software packages that let developers select the support that best meets their needs: the Starter package (STM32MP1Starter) to quickly and easily start with any STM32MP1 microprocessor device; Developer package (STM32MP1Dev) to add your own code on top of the STM32MP1 Embedded Software distribution; and Distribution package (STM32MP1Distrib) to create your own Linux distribution as well as your own Starter and Developer packages.
