How to change the display logo in u-boot

Vincent Wu

Hi all,

Refer to the website patch : http://review.omapzoom.org/#/c/23975/ , I can display a TI logo during uboot stage, but how to replace TI logo with my logo?

I know the "static char * header_data" in the logo.h file that contains the desired splash screen bitmap.How to create my logo.h file ? Is there any tools ?

Thank you.

Hello Vincent,

You will need to use The Gimp:

http://www.gimp.org/

to save a picture in "C header file format" as opposed to GIF, JPG, XPM, etc.. Here's a discussion of that:

Hi Vincent,

I think that's going to be a little difficult to do. Most Android systems I've seen will display one logo for the bootloader, and then another when Android starts.

It should be possible to set up a boot logo in the Linux kernel itself, before Android starts. But there would still be a little time where the screen will be blank.

Best regards,

James
