Yes, there are no interrupts serviced (and thus no timer 'ticks') until
the scheduler is started.

Hi,
i want to change the real time clock resolution from 100 ticks/sec to
1000 ticks/sec for
eCos running on an Assabet board. I am developing eCos on a Linux
machine
so i have to manually configure eCos if necessary.
I noticed that i cannot change the ecos.ecc (configuration file) because
the real time clock resolution is not modifiable by the user.
So i tried to obtain a handle to the real time clock and change the
resolution
inside cyg_user_start() but the resolution remains the same.
Is it a limitation of the board or am i doing something wrong ?
thanks,
vlasios
