static bool is_wdt_reset ( void  )

static

Check if the WDT reset happened.

Returns

True for WDT reset happened, false for not happened.

Referenced by run_wdt_test_all().

int main

(

void

)

Run WDT driver unit tests.

static void mdelay ( uint32_t  ul_dly_ticks )

static

Waits for the given number of milliseconds (using the g_ul_ms_ticks generated by the SAM's microcontrollers's system tick).

Parameters

ul_dly_ticks

Delay to wait for, in milliseconds.

References g_ul_ms_ticks.

Referenced by run_wdt_test_all().

static void run_wdt_test_all ( const struct test_case *  test )

static

Test watchdog for all cases.

Note

Because MCU will be reset serval times druing the test, to simplify the design, only one test case but with many test stages.

Parameters

test	Current test case.
