Arria V remote update - watchdog

While in factory configuration can I use the remote update watchdog as a watchdog?

I set:

IOWR(REMOTE_UPDATE_0_BASE, 0x1, 0x131); //Set wachedog time.
IOWR(REMOTE_UPDATE_0_BASE, 0x2, 1); //Enable watchdog.

The clock is 20MHz.

It never seems to trip. Is it because it is designed to reset to factory config if an application config fails and will never trip while in factory config?

Thanks.

    Hi,


    The watchdog timer is only use when you reconfigure to Application Image using Remote Update IP. When the Watchdog timer timeout then it will trigger reconfiguration back to factory image.


    So yes, this watchdog timer cannot be used in factory image.
