Good morning, everyone,
I am working on a board that mounts STM32FMP25x, with Yocto, and I am having problems with the kernel logo.
I've enabled and customized the pslash-drm image and that works (it would be curious to understand why it has to be 1 px narrower and 1 px shorter than the screen resolution but that's another task).
Problem: the boot is really slow and I need something to appear on the screen before the 20'' needed for the psplash-drm to appear.
I am not a great expert, but from what I remember of Yocto, and the Linux kernel, it should also be possible to make a kernel logo appear (so I have done with all the platforms I have worked on in the past).
In the .config of my kernel the CONFIG_LOGO_LINUX_CLUT224=y entry is set correctly, but unfortunately I don't see anything on the screen.
I do not understand if and what I am doing wrong.
I have not customized the image yet so the problem should not be about the image format.
Do you have any advice?
I thank you very much in advance.

Hi @Merlino
have you tried to use uBoot splash screen ?

I guess they are two different things...
I'll also try to add u-boot splash screen (hoping i can set a custom size image) but my question is about kernel splash screen.
