Amazon FreeRTOS: Training, Porting, & Licensing

FreeRTOS is one of the most popular open source embedded RTOS’s in the world. WHIS offers enhanced products and services for the FreeRTOS kernel, and the whole of Amazon FreeRTOS. We offer:

  • Porting services to your specific processor/compiler
  • FreeRTOS training
  • Commercial licensing

A Joint History with FreeRTOS

The FreeRTOS kernel is a real-time operating system for microprocessors, that is free to download from Richard Barry created FreeRTOS in 2003 while an employee at WHIS. We worked closely with Richard, providing a safety critical upgrade to FreeRTOS called SAFERTOS, and the flexible commercial licensing, training, and support that FreeRTOS users needed.

In 2017 AWS announced stewardship of FreeRTOS. WHIS continues to be the market leaders when it comes to professional FreeRTOS services.

What is Amazon FreeRTOS?

Amazon FreeRTOS extends the FreeRTOS kernel with software libraries from AWS, that make it easy to securely connect your small, low-power devices to cloud services such as AWS IoT Core or to more powerful edge devices such as those running AWS IoT Greengrass.

Amazon Web Services and WITTENSTEIN high integrity systems Strategic Business Alliance

At AWS re:Invent 2017, AWS announced Amazon FreeRTOS; based on the FreeRTOS kernel it is part of the AWS Edge to Cloud IoT offering, with Richard Barry joining AWS. This enables greater investment in the FreeRTOS kernel to the benefit of developers and manufacturers bringing new edge devices to the market. AWS immediately integrated connectivity and over-the-air (OTA) update capabilities, as well as additional security enhancements. WHIS continues to support the FreeRTOS kernel with professional licensing and a migration path to our safety critical software in AWS IoT devices as part of our strategic business alliance with Amazon Web Services (AWS), as well as continuing to serve our broad customer base in industry sectors such as medical, automotive and aerospace.

About Amazon Web Services

Amazon Web Services (AWS) is a secure cloud services platform, offering computing power, database storage, content delivery and other functionality to help businesses scale and grow.

Amazon FreeRTOS provides tools you need to quickly and easily deploy a microcontroller-based connected device and develop an Internet of Things (IoT) application without having to worry about the complexity of scaling across millions of devices. Once connected, IoT device applications can take advantage of all of the capabilities of the cloud or continue processing data locally with AWS Greengrass. Visit the AWS a:FreeRTOS Pages here.

Safety Critical IoT Applications

WHIS provides a simple upgrade path from the FreeRTOS kernel to SAFERTOS. SAFERTOS provides developers with a responsive, deterministic embedded Real Time Operating System (RTOS) with a Design Assurance Pack that provides an easy route to achieving certification of SAFERTOS once integrated into a Safety Product. More than that, SAFERTOS is packed with safety features such as Task Isolation and Separation, which allow developers to co-locate safety critical code with non-safety critical code such as Amazon FreeRTOS libraries, using the processor’s MPU/MMU. More about SAFERTOS here.

Commercial Licensing

WHIS has always offered commercial licensing for the FreeRTOS kernel, now distributed under an MIT license, and continues to do so for the entirety of Amazon FreeRTOS. Contact us for more information about our flexible licensing and our professional support, or find out more here.

SAFERTOS comes with an industry-tailored Design Assurance Pack (DAP) that supports certification for your relevant market.

Available Design Assurance Packs include:
