[ECOS] Time Slice

[ECOS] Time Slice

[Chandrasekhar G]

Hi,
     I am running a program on Linux Synthetic Target.  I configured for the
scheduler 'mlqueue' and enabled time slicing.   After each tick the clock DSR
is calling Cyg_Scheduler::scheduler.timeslice().  While debugging, I want to
single step into this routine.  I am using 'Insight' for debugging on Linux. 
Can anybody suggest a solution?

Thank you
chandra

You mean that you are in the clock DSR and you want to single step into the
Cyg_Scheduler::scheduler.timeslice() but it doesn't work? You should be
able to. 

Or are you just trying to find the function? It's in mlqueue.cxx. Go to
that file in Insight and set a breakpoint at the beginning.

OOI in general, if debugging features like this don't work, if at all
possible turn optimization off - i.e. in the Global compiler flags, remove
the -O2 flag. Then do a Build->Clean, followed by Build->library to rebuild
the library.

OOI in general, if debugging features like this don't work, if at all
possible turn optimization off - i.e. in the Global compiler flags, remove
the -O2 flag. Then do a "make clean" followed by "make" in your build tree.
