Splash Screen
|
|
---------------------------------------------------------------------
|
|
The splash_screen_prepare() function is a weak function defined in
|
|
common/splash.c. It is called as part of the splash screen display
|
|
sequence. It gives the board an opportunity to prepare the splash
|
|
image data before it is processed and sent to the frame buffer by
|
|
U-Boot. Define your own version to use this feature.
|
|
|
|
CONFIG_SPLASH_SOURCE
|
|
|
|
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.
|
|
|
|
splashsource 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, or storage
|
|
formatted with a file system. 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".
