The kernel splashscreen allows 224 colors. It also allows up to the full screen resolution, but for fastest boot speed it should be kept as small as possible. The image will be centered around a black background.

To convert your image, for example, "mylogo.png":

convert mylogo.png mylogo.ppm
ppmquant 224 mylogo.ppm > mylogo-224.ppm
pnmnoraw mylogo-224.ppm > logo_user_clut224.ppm
cp logo_user_clut224.ppm <kernel build sources>/drivers/video/logo/

Now recompile the kernel following the guide in the previous section.

If you would like to disable the kernel logo completely you can add the kernel cmdline "logo.nologo" in u-boot.
