- Subject: [ECOS] is nano sleep is realtime waken up
Hai,
The nanosleep API provided by the eCos is realtime. i mean if i want
to sleep for 50 milli seconds whether it will sleep exactly 50 milli
seconds irrespective of the load on the CPU.
i am facing small problem with this sleep.
the problem is
1. i am creating one thread(POSIX created with pthread) with the priority
16( avcerage priority) and sleeping for 50 milli seconds
2. parllely i have created 10 other threads (this is also POSIX) with the
pririty of 31 (low)which will do following thing (without any sleep)
while(1);
3. the Sleeping thread is waken up after around 600 milli seconds.
please suggest me any options/settings will give good results to me
Thanks Regards
Gntpl
