Embracing Open Source Software

-FreeRTOS™ Support for Arm-v8 architecture-


"The inclusion of FreeRTOS as a guest of the LynxSecure separation kernel hypervisor will give developers an easy and low-cost path to development and integration of complex systems, with a path to a fully safety-certifiable solution."

Moving with the market

Lynx real-time operating systems have been proven and deployed at scale across a wide range of security- and safety-critical applications, especially in aerospace and defense markets. Over the years, we have witnessed increased adoption of open source OSes in embedded systems designs and have decided to embrace a broader set OSes to work out-of-the-box with our secure hypervisor product, LynxSecure, and our complete development and integration framework, LYNX MOSA.ic™.

Therefore, to deliver further on our commitment to the Modular Open Systems Approach (MOSA) and to accommodate a wider range of customer choices, we announced in February 2020 that we are embracing FreeRTOS as a supported guest OS.

FreeRTOS adoption graphs


Our own research as well as 3rd party research indicates that the most popular OSes used in embedded systems are (1) Linux; (2) in-house/custom OSes; and (3) FreeRTOS. Lynx loves Linux and already offers Buildroot in LYNX MOSA.ic™. We also support a number of 3rd party OSes (and will even support competitor OSes) while of course offering our own RTOSes where suitable, but FreeRTOS was noticeably absent.

As the #2/#3 OS of choice currently and as the OS planned for fully a third of upcoming embedded projects, adding FreeRTOS support was a clear choice as we continue to deliver on the vision of MOSA by providing customers with open source solutions within a secure and safe development framework.

Finally, FreeRTOS truly embodies what we think a Guest OS in Lynx technologies should be:

  • It’s modular
  • It provides a path to safety certification
  • Thanks to the investment by Amazon, there are now a broad set of hooks to assist with cloud connectivity which will shorten customer development cycles and costs

First Steps

Supporting FREERTOS



Based on customer demand, we are starting this engineering work around the Arm architecture, focusing more specifically on the Xilinx Zynq product family. We will be making this available in the summer of 2020.

Email us to be kept up-to-date with progress on this engineering effort. Alternatively, you can start immediately with your code development for Zynq, which is available to run on LynxSecure once the port is complete.
