If found, the usual display - of logo, copyright and system information on the LCD - is suppressed and the BMP image at the address - specified in "splashimage" is loaded instead. The - console is redirected to the "nulldev", too. This - allows for a "silent" boot where a splash screen is - loaded very quickly after power-on. - - CONFIG_SPLASHIMAGE_GUARD - - If this option is set, then U-Boot will prevent the environment - variable "splashimage" from being set to a problematic address - (see doc/README.displaying-bmps). - This option is useful for targets where, due to alignment - restrictions, an improperly aligned BMP image will cause a data - abort. If you think you will not have problems with unaligned - accesses (for example because your toolchain prevents them) - there is no need to set this option. - - CONFIG_SPLASH_SCREEN_ALIGN - - If this option is set the splash image can be freely positioned - on the screen. Environment variable "splashpos" specifies the - position as "x,y". If a positive number is given it is used as - number of pixel from left/top. If a negative number is given it - is used as number of pixel from right/bottom. You can also - specify 'm' for centering the image. - - Example: - setenv splashpos m,m - => image at center of screen - - setenv splashpos 30,20 - => image at x = 30 and y = 20 - - setenv splashpos -10,m - => vertically centered image - at x = dspWidth - bmpWidth - 9 - - Gzip compressed BMP image support: CONFIG_VIDEO_BMP_GZIP If this option is set, additionally to standard BMP |
