[ECOS] Clock and delay problem

[Fabrice Gautier <Fabrice_Gautier at sdesigns dot com>]

Hi,

In my eCos program there is a momemt where the clock doesn't advance no
more.
I'm using an i386 PC platform
I've a loop like this:

while ( /*some condiditon*/ )
{
	i++;
	if( (i & 0x1FF) == 0x1FF)
	{
		printf("%04d - time : %u \n",i,cyg_current_time());
		asm("int $3");
	}
	cyg_thread_delay((cyg_tick_count_t)1000);
}

The printf is executed every 512 loop and each time it print the same time.
And the cyg_thread_delay doesn't take more time than an other normal
instruction.

What can explain this behaviour?
There is probably something in my program that cause this effect for if I do
a similar test at the beginning of the program I've no problem.

***

After some investigations, I can tell that the clock ISR is called, but not
the DSR. That's annoying for the clock update is done in the DSR. I tried to
step throught the ISR and DSR but it seems impossible since when I am in
interrupt_end, there is another IRQ0I came back in the ISR. 

I don't understand how it comes that the DSR is not executed but the main
thread is. Maybe this explain also why there is no rescheduling in the
cyg_thread_delay call.


Thanks
