Thank you Richard,
this sounds promising.
Please let me get back to the tick issue once more:
What our application basically does, is sampling a sensor with 200Hz, performing some signal processing for 1 millisecond and than disabling ALL interrupts and switching to low clock cycle, thus nearly shutting it down for 4 milliseconds (in order to preserve battery charge). The only way to get back from this state is by a signal from the real time clock via an advanced interrupt controler.
So my thoughts circle around the question whether there was a way to interface FreeRTOS with this signal.
best regards,
Christian
