STM32 MPU OpenSTLinux Distribution

As a mainlined open-source Linux distribution, OpenSTLinux Distribution is a key element of the STM32 Embedded Software solution for STM32 multi-market multi-core microprocessors (MPU) embedding a single or dual Arm^® Cortex^®-A7 core.

Developers should note that OpenSTLinux Distribituion is not a specific, custom Linux distribution. By massively investing in mainlining the OpenSTLinux Distribution, ST demonstrates its dedication to:

• Accelerating the development of systems that needs high processing power, graphical support combined with power-efficient real-time control and high feature integration
• providing developers with an unprecedented level of support

Designers working on a wide range of applications including Industrial, Consumer, Medical and Smart Home will benefit from:

• Seamless software migration during kernel upgrades
• Improving software quality and robustness as well as reducing risk
• Development resources allocated to new innovative functionalities at application level
• Reducing project time to market and cost

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 the following Linux application frameworks (non-exhaustive list):
  • Wayland display server protocol (Weston reference implementation)
  • Gstreamer multimedia framework
  • Advanced Linux Sound Architecture (ALSA) libraries

To optimize each development phase of a project, ST offers software packages that let developers select the support that best meets their needs:

• 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
• Distribution package (STM32MP1Distrib) to create your own Linux^® distribution as well as your own Starter and Developer packages
