Hey, 

I want to use the remote update controller for my design and I also want to use the Watchdog Timer feature to control that the software Image is loaded correctly so I want to disable the timer in my Applikation Image. 

 

But it does not work. 

 

I tried like this: 

IOWR( REMOTE_UPDATE_CYCLONEIII_0_BASE, 0x20, 0x02 );// reset and stop WDTand my secound try was  

IOWR( REMOTE_UPDATE_CYCLONEIII_0_BASE, 0x03, 0x00 );but it is not working... 

 

Maybe someone here have an idea. 

 

regards Tobias

I think you cannot disable the watchdog timer when its started.

Thank you for the reply 

After reading some examples I also come to this conclusion.  

But if someone here find a way to disable the timer in application mode let me know. Would be very useful.

Maybe you can reset the watchdog timer periodiclly, just make sure the reset_timer period is shorter than the watchdog timeout time.
