|
|
|
+ Use the splash_source.c library. This library provides facilities to
|
|
|
+ declare board specific splash image locations, routines for loading
|
|
|
+ splash image from supported locations, and a way of controlling the
|
|
|
+ selected splash location using the "splashsource" environment
|
|
|
+ variable.
|
|
|
+
|
|
|
+ This CONFIG works as follows:
|
|
|
+
|
|
|
+ - If splashsource is set to a supported location name as defined by
|
|
|
+ board code, use that splash location.
|
|
|
+ - If splashsource is undefined, use the first splash location as
|
|
|
+ default.
|
|
|
+ - If splashsource is set to an unsupported value, do not load a splash
|
|
|
+ screen.
|
|
|
+
|
|
|
+ A splash source location can describe either storage with raw data, a
|
|
|
+ storage formatted with a file system or a FIT image. In case of a
|
|
|
+ filesystem, the splash screen data is loaded as a file. The name of
|
|
|
+ the splash screen file can be controlled with the environment variable
|
|
|
+ "splashfile".
|
|
|
+
|
|
|
+ To enable loading the splash image from a FIT image, CONFIG_FIT must
|
|
|
+ be enabled. The FIT image has to start at the 'offset' field address
|
|
|
+ in the selected splash location. The name of splash image within the
|
|
|
+ FIT shall be specified by the environment variable "splashfile".
|
|
|
+
|
|
|
+ In case the environment variable "splashfile" is not defined the
|
|
|
+ default name 'splash.bmp' will be used.
