II. Watchdog support
|
|
|
|
For security reasons, the at91 watchdog is running at boot time and,
|
|
if deactivated, cannot be used anymore.
|
|
If you want to use the watchdog, you will need to keep it running in
|
|
your code (make sure not to disable it in AT91Bootstrap for instance).
|
|
|
|
In the U-Boot configuration, the AT91 watchdog support is enabled using
|
|
the CONFIG_AT91SAM9_WATCHDOG and CONFIG_HW_WATCHDOG options.
