u-boot splash screen on DM3730

Hi Suhas,

It seems that your uboot supports splash screen, but you should check have you added a "#define CONFIG_SPLASH_SCREEN" to your board configuration file. In order to display the splash screen image that resides in the flash, the splashimage environment variable must be set. The splashimage variable should contain the base address for splash screen shadow in RAM.

thnx for ur timely reply....... :)

Did u mean i should  include the line   "#define CONFIG_SPLASH_SCREEN     1"  in    "/uboot-2010.06/include/configs/omap3evm.h" under the section 'Display CPU and Board information'?????????

am i correct????????

Also can u explain how to use splashimage environment variable in detail .... i.e. is the bmp image already included  in u-boot?

1. How to load the bmp image to RAM?

2. At wat RAM address?

Thnx in advance once again....... :)

You are correct about the CONFIG_SPLASH_SCREEN defining.

Many uboots contains some support of splash image. I advise you to check this by the grep "splashimage" ./ -R command and pat attention to the files which contain "splashimage".

You could read a short tutorial about splash image at:

thnx for that....... :)

since we r using custom display  with different display parameters...such as resolution 1024*600 and pixel clk of  50MHz... i need to know where do i set display parameters such as resolution,pixel clk,hfp,vfp,hbp,vbp..etc...etc...  i think just by setting CONFIG_SPLASH_SCREEn will not enable the splash screen... any other thing is needed?

can u throw some light on it...

thnx in advance.. :)

Hi Suhas,

Your u-boot should be has support for splash screen. You can check it if go to u-boot folder and open ./README file. Then search for "splash".

You can read about configuring of screen resolution settings in the comments in the beginning of the ./drivers/video/videomodes.c file.
