In my project, I need to display a logo during boot up. In u-boot I’m able to display the boot logo by reading the boot logo file from flash.
But once kernel boot, it re-initialize framebuffer and splash screen is gone. In the following post, it is mentioned that using drm_fb_helper_remove_confliciting_framebuffers we can continue uboot splash screen during kernel boot.
Can anyone give more detail or some example on how to implement the boot logo based on DRM driver.
