The Linux® Operating System (OS) has become pervasive in all aspects of the digital world, largely due to its long-standing history as one of the most reliable, secure and worry-free operating systems available. The Linux OS and Microchip’s microprocessors (MPUs) have gone hand in hand since 2002 when our first MPU, the AT91RM9200, was introduced.
By supporting mainline Linux, we provide a way for you to receive the full support of the open-source community to create high-quality solutions. We have been mainlining our kernel, bootloader and drivers since 2004, and mainlining has become a centerpiece of our Linux strategy because of the value it brings to users. We use our linux4sam.org website to provide access to new developments, which are reviewed by our Linux maintainers and fully tested on our hardware platforms. Using Long-Term Support (LTS) Linux kernels provides access to kernel maintenance for two to six years. Linux provided by Microchip still uses the AT91RM9200 peripheral drivers, thus facilitating software portability between each kernel release, eliminating the need to update drivers.
To get started with Linux on our MPUs and explore the potential of the combined hardware and software platform, we recommend the ATSAM5D27-SOM1-EK1 evaluation kit. Watch this video to learn more:
Getting Started with Linux on the ATSAMA5D27 SOM Evaluation Kit
In this video, we will demonstrate how to get started running Linux on the ATSAMA5D27-SOM1-EK1 Evaluation Kit. We will show you how to quickly and easily download a demo image, write it to an SD card, and boot Linux on the evaluation kit. We will show you where to find more information to help you get started developing embedded Linux applications for the SAMA5D2 family of MPUs.
- Device tree support
- Yocto and Buildroot build environments
- Solid and proven peripheral drivers
- Large developer community
- Security updates
- Maintaining multiple stable kernels
Yocto Project
The Yocto Project® is an open source collaboration project that provides templates, tools, methods and documentation to help developers create Linux-based systems for embedded products. The free tools make getting started easy, are powerful to work with (including emulation environments, debuggers, an Application Toolkit Generator, etc.) and allow projects to evolve across all stages of development from prototype to production.
