Customizing the splash screen[edit | edit source]
Resources[edit | edit source]
For further details on splash screen support in U-Boot, please refer to:
Instructions[edit | edit source]
The following U-Boot environment variables are required:
- splashimage: RAM address where the BMP image is loaded. Please note that it must be a 32-bit aligned address with a 0x2 offset (eg: 0x20000002)
- loadsplash: comand for loading the BMP image from the storage device (e.g flash memory) to RAM. This command is automatically run by U-Boot at startup
U-Boot variables[edit | edit source]
loadsplash=run mmc_loadsplash
mmc_loadsplash=ext4load mmc ${mmcdev}:1 ${loadaddr} ${splashfile}; cp.b ${loadaddr} ${splashimage} ${filesize}
splashfile=splash_image.bmp
splashimage=0x50000000
Please note that the eMMC first partition is used for storing the splash image file. The BMP should be present into this partition (formatted as ext2, ext3 or ext4).
