Ah, thanks. I read it on a phone as 20KHz and was confused and did not
reread.
I have assumed that he meant this was the largest clock tick time
quantum which is reasonable to configure.
20 Hz is supposed to be the slowest frequency the rtems_clock_tick()
should be called.
50msec is fine with me even on a slow cpu clock speed.
Why is that?
At the moment, I think 20 Hz are needed to ensure a correct
functionality of the 10 timehands structure. Further explanation
is given in the currently last comment of the ticket
(https://devel.rtems.org/ticket/2271#comment:9).
Also I wonder what the code size trade off is for small memory targets
compared to what we currently have ?
