Figure 12–4. Transitions Between Configurations in Remote Update Mode
After power up or a configuration error, the factory configuration logic is loaded
automatically. The factory configuration also needs to specify whether to enable the
user watchdog timer for the application configuration and if enabled, to include the
timer setting information as well.
The user watchdog timer ensures that the application configuration is valid and
functional. The timer must be continually reset within a specific amount of time
during user mode operation of an application configuration. Only valid application
configurations contain the logic to reset the timer in user mode. This timer reset logic
should be part of a user-designed hardware and/or software health monitoring signal
that indicates error-free system operation. If the timer is not reset in a specific amount
of time, for example, the user application configuration detects a functional problem
or if the system hangs, the dedicated circuitry updates the remote system upgrade
status register, triggering the loading of the factory configuration.
The user watchdog timer is automatically disabled for factory configurations. For
more information about the user watchdog timer, refer to
page
If there is an error while loading the application configuration, the cause of the
reconfiguration is written by the dedicated circuitry to the remote system upgrade
status register. Actions that cause the remote system upgrade status register to be
