The ThreadX Alliance offers specific versions of the Eclipse ThreadX RTOS that have been certified for use in safety-critical applications. If you intend to certify your product or device, you can only use the component versions for which a certificate is available. Get the open source ThreadX RTOS here.
ThreadX Alliance members can purchase a license for the ThreadX RTOS safety artifacts package, which contains a full set of safety manuals and other documents for every certified ThreadX RTOS release.
