Change the splash screen

Hello,

I wanted to ask you if somebody knows how to change the spash screen image that is shown during boot at the hdmi screen.
Does this invlolve playing around with uboot?
Thank you in advance!

 

Hi there fischers,
yes it involves recompilation of the Uboot.
Cheers,
Andrea

 

Hey!
Thanks I have feared that this will be neccessary...
I will see if I pursue this any further.

 

Fischers, are you finished cange boot splash image?
how i can do?

 

Hi,

I've been playing around with the u-boot source but I haven't been able to modify the splash image. So far it seems like the image is not in a *.h or in the u-boot source.

Could you please tell me what routine are you using to set the image? So far it seems like it does not use u-boot procedures (the environment variable splashimage is not set).

Thanks!
Manuel

 

I just figured out how it is being done.

It is being carried out by the Makefile using the bmp_logo tool.

Easy way to change to logo:
Go to /tools/logos
Delete or change the name to the udoo.bmp file that is in there and copy the image you want to display in that folder with the name udoo.bmp

Do a make clean, rebuild and load U-boot to your SD card, now you should be able to see the new logo.

The "hard" way involves messing around with /tools/Makefile at line 188. You could simply comment out everything and hardcode your logo there.

Thanks!
Manuel

 

Thank's Manuel, I was successful change over replace udoo.bmp. But how i can get splash screen to full or at least close to side?

Hi Herionoindo,

To set the position of the image simply modify the environment variable splashpos on include/configs/udoo_qd.h line :131

m,m centers the image, the position is specified in an x,y format. For more details open the README file on the U-boot directory, line :1982. I use vim so you can simply use VIM and do /CONFIG_SPLASH_SCREEN_ALIGN to look at the details.

To cover the full screen I think you would have to use an image with the same resolution that your display has and set splashpos=0,0.

That is my guess I haven't tried it.

Regards,
Manuel

 

Thank's i'v done..
Manuel, do you know how to disable framebuffer u-boot udoo android?
Because after show splash screen goto blank and flicker in time, before Bootanimation appears. I want to keep splash screen until Bootanimation was ready. I find tutorial on "toradex colibri board" but not success apply in udoo android.
