Dear Sir,
I am testing RTEMS POSIX thread priority.
I am still using RTEMS 4.12 in 2017 year.
There are four pthreads(main, pthread1, pthread2, pthread3) on two cores in
my test case.
- main pthread is running on core 1.
- pthread1, pthread2, pthread3 is running on core 2.
- All threads
pthread1/2/3s
because the main thread has never chance to run it, which is required to other
threads.
However why do you assign so much long integer value to priority?
Cheol

Hi
I'm off for the holidays and answering from my phone. My suspicion is that the
pthread command is an alias for the tasks command. Thus it is not reporting the
priority fro
RealView PBX A9.
