/* Common commands
|
|
*
|
|
* CMD: BOARDIOC_INIT
|
|
* DESCRIPTION: Perform one-time application initialization.
|
|
* ARG: The boardctl() argument is passed to the
|
|
* board_app_initialize() implementation without modification.
|
|
* The argument has no meaning to NuttX; the meaning of the
|
|
* argument is a contract between the board-specific
|
|
* initialization logic and the matching application logic.
|
|
* The value could be such things as a mode enumeration value,
|
|
* a set of DIP switch switch settings, a pointer to
|
|
* configuration data read from a file or serial FLASH, or
|
|
* whatever you would like to do with it. Every
|
|
* implementation should accept zero/NULL as a default
|
|
* configuration.
|
|
* CONFIGURATION: CONFIG_BOARDCTL
|
|
* DEPENDENCIES: Board logic must provide board_app_initialize()
|
|
*
|
|
* CMD: BOARDIOC_POWEROFF
|
|
* DESCRIPTION: Power off the board
|
|
* ARG: Integer value providing power off status information
|
|
* CONFIGURATION: CONFIG_BOARDCTL_POWEROFF
|
|
* DEPENDENCIES: Board logic must provide the board_power_off() interface.
|
|
*
|
|
* CMD: BOARDIOC_RESET
|
|
* DESCRIPTION: Reset the board
|
|
* ARG: Integer value providing power off status information
|
|
* CONFIGURATION: CONFIG_BOARDCTL_RESET
|
|
* DEPENDENCIES: Board logic must provide the board_reset() interface.
|
|
*
|
|
* CMD: BOARDIOC_PM_CONTROL
|
|
* DESCRIPTION: Manage power state transition and query
|
|
* ARG: A pointer to an instance of struct boardioc_pm_ctrl_s
|
|
* CONFIGURATION: CONFIG_PM
|
|
* DEPENDENCIES: None
|
|
*
|
|
* CMD: BOARDIOC_UNIQUEID
|
|
* DESCRIPTION: Return a unique ID associated with the board (such as a
|
|
* serial number or a MAC address).
|
|
* ARG: A writable array of size CONFIG_BOARDCTL_UNIQUEID_SIZE in
|
|
* which to receive the board unique ID.
|
|
* DEPENDENCIES: Board logic must provide the board_uniqueid() interface.
|
|
*
|
|
* CMD: BOARDIOC_MKRD
|
|
* DESCRIPTION: Create a RAM disk
|
|
* ARG: Pointer to read-only instance of struct boardioc_mkrd_s.
|
|
* CONFIGURATION: CONFIG_BOARDCTL_MKRD
|
|
* DEPENDENCIES: None
|
|
*
|
|
* CMD: BOARDIOC_ROMDISK
|
|
* DESCRIPTION: Register a ROM disk
|
|
* ARG: Pointer to read-only instance of struct boardioc_romdisk_s.
|
|
* CONFIGURATION: CONFIG_BOARDCTL_ROMDISK
|
|
* DEPENDENCIES: None
|
|
*
|
|
* CMD: BOARDIOC_APP_SYMTAB
|
|
* DESCRIPTION: Select the application symbol table. This symbol table
|
|
* provides the symbol definitions exported to application
|
|
* code from application space.
|
|
* ARG: A pointer to an instance of struct boardioc_symtab_s
|
|
* CONFIGURATION: CONFIG_BOARDCTL_APP_SYMTAB
|
|
* DEPENDENCIES: None
|
|
*
|
|
* CMD: BOARDIOC_OS_SYMTAB
|
|
* DESCRIPTION: Select the OS symbol table. This symbol table provides
|
|
* the symbol definitions exported by the OS to kernel
|
|
* modules.
|
|

|
|
* name-value pairs for associating built-in application
|
|
* names with user-space entry point addresses. These
|
|
* globals are only needed for use by BINFS which executes
|
|
* built-in applications from kernel-space in PROTECTED mode.
|
|
* In the FLAT build, the user space globals are readily
|
|
* available. (BINFS is not supportable in KERNEL mode since

* user-space address have no general meaning that
|
|
* configuration).

|
|

* Name: boardctl
|
|
*
|
|
* Description:
|
|
* In a small embedded system, there will typically be a much greater
|
|
* interaction between application and low-level board features. The
|
|
* canonically correct to implement such interactions is by implementing a
|
|
* character driver and performing the interactions via low level ioctl
|
|
* calls. This, however, may not be practical in many cases and will lead
|
|
* to "correct" but awkward implementations.
|
|
*
|
|
* boardctl() is non-standard OS interface to alleviate the problem.
|
|
* It basically circumvents the normal device driver ioctl interlace and
|
|
* allows the application to perform direct IOCTL-like calls to the
|
|
* board-specific logic.
|
|
* It is especially useful for setting up board operational and test
|
|
* configurations.
|
|
*
|
|
* Input Parameters:
|
|
* cmd - Identifies the board command to be executed
|
|
* arg - The argument that accompanies the command. The nature of the
|
|
* argument is determined by the specific command.
|
|
*
|
|
* Returned Value:
|
|
* On success zero (OK) is returned; -1 (ERROR) is returned on failure
|
|
* with the errno variable set to indicate the nature of the failure.
