* Name: board_app_initialize
|

*
|

* Description:
|
||||
* Perform application specific initialization. This function is never
|
||||
* called directly from application code, but only indirectly via the
|
||||
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
|
||||
*
|
||||
* Input Parameters:
|
||||
* 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 cold 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.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.
