Hey folk's
I have a strange problem,
Following code is running well in development mode.
When I reboot (power cycle) the system hangs.
When I change the fuse NOWDT in WDT, the system starts up, but restarted every XXX seconds...
What could be the problem?

When you have the watchdog enabled, it must be "tickled" frequently to
tell the code that everything is working correctly.
restart_wdt();//at least one in the main while(1) loop
Your delays may not work with wdt on without using
#use delay(clock=18432000,RESTART_WDT) |

Yes ! This is working !
Only I don't know why the pic is not booting without the WDT.
Now the time between power and booting is really long (about half a minute). Any sugestions to decrease this time?
Thanks

I am seeing this same problem.
My guess is that the external clock needs some time to stabilize.
What is happening is that you may be getting an oscillator fail trapped and the code hangs until the WDT expires (30s in your case).
I believe the solution is to enable clock switching and start with the internal clock 7.37Mhz and then switch the external crystal and few seconds later.
What was your final solution? |

Post your fuses, crystal frequency, what speed you are trying to run, the exact chip, and compiler version.
The original post has several problems, such as 'EC', as well as 'HS2'. These are 'either/or' fuses, not both. So the actual configuration may well have not been 'viable'. The frequency that was being used (64MHz), is also not viable for the PLL4 selection. Look at table 20-3 in the data sheet....

Hi there,
resonator=16Mhz clock=32Mhz using (HS/2 PLLx4)
it did give me error in compiler when i tried to use below line.
#use delay(clock=32Mhz,crystal=16Mhz)
Please find my code below. I tried to use watchdog but still cant get the startup time to below 16seconds. Ideally want it to start up straight away.
This works fine when I change the clock to 16MHz (withouth the PLL).
Also starts straight away in Clock=32MHz (with PLL) but only when ICD3 is connected to micro. Never seen this prob before.

Seriously 1000* more complicated than it should be to debug a problem like this.
All you should have is a simple 'flash an LED' type program, and you can then see immediately how quickly the processor starts. With lots of extra code, the problem could be that it is waiting for something.....
The flash an LED program will also confirm the actual clock rate.
So:
| Code: |
#include <30F4013.h>
#fuses HS2_PLL4,NOWDT,NOPROTECT,NODEBUG,PUT4,NOBROWNOUT,NOMCLR
#use delay(clock=32Mhz)
void main(void)
{
do
{
output_toggle(PIN_F0);
delay_ms(1000);
}
while (TRUE);
}
|
on a 3014 (haven't got a 3013), with just the processor include changed, wakes up only a few mSec after power is applied, and the LED toggles at the right interval.
