How to show Kernel Logo on am3517?

Other Parts Discussed in Thread: AM3517

Hi,

I am testing TI-Android-GingerBread-2.3-DevKit-1.0 on our custom board with AM3517,  and connected with a 7" LCD, its resolution is 800*480, My kernel version: 2.6.32.

I want to show a logo during kernel booting, I enabled bootup logo in kernel.

 

------------------------------------------------------------------------------------------------

 

-> Device Drivers

    -> Graphics support

      -> Bootup logo (LOGO [=y])

--- Bootup logo

[ ]   Standard black and white Linux logo

[ ]   Standard 16-color Linux logo

[*]   Standard 224-color Linux logo

------------------------------------------------------------------------------------------------

 

However, No logo was shown during the kernel booting. 

Is there any other option should be enabled in kernel, or what else should I do to implement it?

 

Thanks,

Kevin

    Have you tried with the 16-color logo option?

    You must enable "CONFIG_FRAMEBUFFER_CONSOLE" to get logo on screen.

     

    Thanks,

    Hello Vaibhav,

    I am displaying customer logo during kernel booting of AM3517 ,it is working but before the logo got displayed (when i power ON ) some lines are displayed in the LCD when i reset the board(without removing the power), before displaying the Logo the previous image(the image on the screen when i pressed the reset button) is appeared blurred.

    Once the kernel is booted,everything looks fine. This issue is only during the bootup. So its looks like that during LCD initialization in the board file that am not clearing the frame buffer so it started displaying the old image (the image on the screen when i pressed the reset button).

    can you please tell me whether my guess is correct ? if so can you guide me to do that ?

    Thanks for valuable time.

    Nice Day,

    Senthil.
