|

|
* 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 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.
|
||||||
|
*
|
||||||
|
* Returned Value:
|
||||||
|
* Zero (OK) is returned on success; a negated errno value is returned on
|

|
* any failure to indicate the nature of the failure.
