Hello,
I've problems with the measurement example
(rtl/examples/measurements/rt_process.o). I am using rtl version 2.0.
When I am trying to run the module with peridoc_mode=1 both, the minimal
and maximal error times are getting higher and higher the longer the
task is running. Below is an example output.
The oneshot_mode works fine. Can anybody explain what the differnces
between these two clock modes are and when to use which mode?
Where can I find information about the clocks (and there modes) used for
scheduling?
BTW: The readme file for this example says
"Parameters:
period: period in milliseconds; default = 1000000"
The period is in nanosecs, or am I wrong?
Thanks in advance
Bernd
