I am running freeRTOS in preemptive mode. Assuming my system will run a very long time without a restart I have come to the conclusion that xTickCount could overflow. I tried to provoke this by using 16 bit tick counter and see what happens to my RTOS and tasks.
For what I have seen everything looks good. No fault times where no task is executed or else.
Nevertheless I am asking you, if somebody knows if there is any other issue concerning long time runs.
Also I am asking about the configTOTAL_HEAP_SIZE, which seems to have absolutely no influence on the system. (Which might be because I am using the heap_3.c??).
