Remote Update Controller WDT in Applikation Image

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 WDT
and 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

    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.
