- Subject: [ECOS] eCos scheduler question
Hi,
I have a question about when the eCos (multi-level) scheduler does a
reschedule
between my application threads.
(Reschedule = Each time the kernel checks if any more priority thread
shall run
instead of the current thread)
As far as I understand, a reschedule is done when one the following
happens:
* Each RTC tick (default 100/second)
* When a message is posted, a semaphore is signalled etc.
* When returning from an ISR (even if DSR is not used)
Anyone know if this is correct?
/Regards
Daniel
