Is it really the compiler that decides this layout? My understanding is that this is decided by the FreeRTOS code. Having used FreeRTOS a few times, my understanding is that it's basically a big library, the compiler doesn't really know about it. For all it knows, you are compiling a bare metal program that happens to implement a task system. Simon
