Remailing cause it did not work first time.
Hi
I have just started programming rtems.
And I see a slow response to events in the order
of 400ms or on my system 80 ticks
(50MHz Leon2 CPU).
I need a event response time closer to 10 ms, or 2 ticks.
I am measuring the response time by setting an IO output
just after sending the event and clearing it after receiving it
in the receiving task..and then I measure on a oscillioscope....
(difficult to spell that one...)
Ive tested by sending the event from a ISR and also a task...
all tasks have the same priority and are preemptive, tested to have
the receiving task no preemptive..this gives slightly better results
otherwise the results are the same.
