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

Please note that loadsplash command will differ depends on used storage device.

Splash image in NOR SPI flash[edit | edit source]

U-Boot variables[edit | edit source]

loadsplash=run spi_loadsplash
spi_loadsplash=sf probe; sf read ${splashimage} 0xa00000 ${splashsize}
splashfile=splash_image.bmp
splashimage=0x80800000
splashsize=0x120000
loadsplashfile=tftpboot ${loadaddr} desk-mxul-l/${splashfile}
spi_updatesplash=sf probe; sf erase 0xa00000 +${filesize}; sf write ${loadaddr} 0xa00000 ${filesize}

Commands[edit | edit source]

The following commands are used to store in NOR SPI flash a BMP image loaded via tftp:

run loadsplashfile
run spi_updatesplash

Splash image in NAND flash[edit | edit source]

U-Boot variables[edit | edit source]

mtdparts=mtdparts=gpmi-nand:2M(nand-SPL),6M(nand-uboot),1M(nand-env1),1M(nand-env2),1M(nand-fdt),1M(nand-spare),8M(nand-kernel),4M(nand-splash),-(nand-ubi)
loadsplash=run nand_loadsplash
nand_loadsplash=nand read ${splashimage} nand-splash ${splashsize}
splashfile=splash_image.bmp
splashimage=0x80800000
splashsize=0x120000
loadsplashfile=tftpboot ${loadaddr} desk-mxul-l/${splashfile}
nand_updatesplash=nand erase.part nand-splash; nand write ${loadaddr} nand-splash ${filesize}

Please note that the NAND mtd partition for the splash image (nand-splash) is defined using the mtdparts parameter, and then referenced by the nand {erase,read,write} commands.

Commands[edit | edit source]

The following commands are used to store in NAND flash a BMP image loaded via tftp:

run loadsplashfile
run nand_updatesplash
