Problems with Watchdog Timer 0

Hello Cesar

The WDTLOCK register is to prevent a write to the WDT Registers. Also once a WDT Timer is enabled it cannot be disabled. The only way to disable it is to Reset the WDT by using SysCtlPeripheralReset Function call.

Hello Amit

Thanks for the information! 

I have another question: ¿Is there any way to "feed the dog"?

Thanks!

Hello Cesar,

What exactly do you want to do with the WDT? The question you phrased rather does not give me any details to give the most appropriate answer...

Hello Amit

I have a program that turns on the red LED, turns on blue LED each 20 ms (indicating that a task was completed), turns off the blue LED and turns on the red LED again. This process is repeated indefinitely.

The program works fine but, when a certain amount of  time passes, the program get stuck unexpectedly.

I think that the problem is the watchdog. What do you think?

Thanks

Hello Cesar,

Where does it get stuck? This is what needs to be debugged

How have you configured the WDT?

1. Is the Interrupt type NMI or a normal Interrupt

2. In either case, NMI or Interrupt, is the application code clearing the Interrupt, If not then it would be stuck in the Interrupt handler (my guess w/o a code post is that this is where the code should be stuck)
