| 166 | III. Watchdog support |
Jean-Christophe PLAGNIOL-VILLARD | 843a265 | 2009-03-27 23:26:42 +0100 | [diff] [blame] | 167 | |
| 168 | For security reasons, the at91 watchdog is running at boot time and, |
| 169 | if deactivated, cannot be used anymore. |
| 170 | If you want to use the watchdog, you will need to keep it running in |
| 171 | your code (make sure not to disable it in AT91Bootstrap for instance). |
| 172 | |
| 173 | In the U-Boot configuration, the AT91 watchdog support is enabled using |
| 174 | the CONFIG_AT91SAM9_WATCHDOG and CONFIG_HW_WATCHDOG options. |
