Free RTOS

FreeRTOS:
There is now a FreeRTOS project for the Arduino Due in the latest Atmel Software Framework (ASF) release, available through the Atmel Gallery

Regards,
Richard (FreeRTOS)

I have the latest Atmel Software Framework (ASF) but I can't find any freeRTOS integration.
Does anybody know how to use freeRTOS in Atmel Studio?
