In sim_timer.c, locate this routine (there are several versions, look
for the last one, which is for UNIX systems):
uint32 sim_os_ms_sleep_init (void)
{
uint32 i, t1, t2, tot, tim;
for (i = 0, tot = 0; i < sleep1Samples; i++) {
t1 = sim_os_msec ();
sim_os_ms_sleep (1);
t2 = sim_os_msec ();
tot += (t2 - t1);
}
tim = (tot + (sleep1Samples - 1)) / sleep1Samples;
if (tim > SIM_IDLE_MAX)
tim = 0;
return tim;
}
If you are running with gdb, place a breakpoint on the line
if (tim > SIM_IDLE_MAX)
and see what the value of 'tim' is. Otherwise, insert the following
before the if statement:
printf ("Calculated minimum sleep time = %d\r\n", tim);
and see what gets printed out.
