examples/watchdog
^^^^^^^^^^^^^^^^^
A simple test of a watchdog timer driver. Initializes starts the watchdog
timer. It pings the watchdog timer for a period of time then lets the
watchdog timer expire... resetting the CPU is successful. This
example can ONLY be built as an NSH built-in function.
This test depends on these specific Watchdog/NSH configurations settings (your
specific watchdog hardware settings might require additional settings).
CONFIG_WATCHDOG- Enables watchdog timer support support.
CONFIG_NSH_BUILTIN_APPS - Build the watchdog time test as an NSH
built-in function. Default: Not built! The example can only be used
as an NSH built-in application
Specific configuration options for this example include:
CONFIG_EXAMPLES_WATCHDOG_DEVPATH - The path to the Watchdog device.
Default: /dev/watchdog0
CONFIG_EXAMPLES_WATCHDOG_PINGTIME - Time in milliseconds that the example
will ping the watchdog before letting the watchdog expire. Default: 5000
milliseconds
CONFIG_EXAMPLES_WATCHDOG_PINGDELAY - Time delay between pings in
milliseconds. Default: 500 milliseconds.
CONFIG_EXAMPLES_WATCHDOG_TIMEOUT - The watchdog timeout value in
milliseconds before the watchdog timer expires. Default: 2000
milliseconds.
