FreeRTOS is an open source and portable, mini Real Time Kernel - a free to download and royalty free RTOS that can be used in commercial applications.
Ports exist for many different processor architectures and development tools. Each official port includes a pre-configured example application demonstrating the kernel features, expediting learning, and permitting 'out of the box' development.
Free support is provided by an active user community. Commercial support along with a full development service is also provided.
SafeRTOSTM is a SIL3 RTOS version that has been certified for use in safety critical applications. It is a functionally similar product for which complete IEC 61508 compliant development/safety lifecyle documentation is available (conformance certified by TÜV SÜD, including compiler verification evidence). While FreeRTOS.org does not contain the same safety features as SafeRTOS there is still commonality - allowing FreeRTOS.org to benefit directly from the very rigorous SafeRTOS testing and validation activities.
