Detailed Description

This file describes the Watchdog Driver for all boards. A watchdog is a hardware device that will reset the board if not touched in a specific way at a regular interval. It is a simple, yet important, part of many embedded systems.

Macro Definition Documentation

◆ WATCHDOG_DRIVER_TABLE_ENTRY

#define WATCHDOG_DRIVER_TABLE_ENTRY { Watchdog_initialize, NULL, NULL, NULL, NULL, Watchdog_control }

This macro defines the watchdog device driver entry points.

Function Documentation

◆ Watchdog_control()

rtems_device_driver Watchdog_control	(	rtems_device_major_number	major,
		rtems_device_minor_number	minor,
		void *	arguments
	)

Watchdog Driver IO Control.

This method implements the IO Control device driver entry point for the watchdog hardware device.

Parameters

[in]	major	is the watchdog device major number
[in]	minor	is the watchdog device minor number
[in]	arguments	points to device driver arguments

◆ Watchdog_initialize()

rtems_device_driver Watchdog_initialize	(	rtems_device_major_number	major,
		rtems_device_minor_number	minor,
		void *	arguments
	)

Watchdog Driver Initialization.

This method initializes the watchdog hardware device. The device should be initialized as DISABLED since BSP initialization may take longer than the timeout period for the watchdog.
