My platform colibri-imx8x+iris2.0
I try add splasch screen in kernel Splash Screen on the Linux Kernel | Toradex Developer Center 
bitbake -c menuconfig virtual/kernel
In menuconfig, go to: Device Drivers → Graphics support → Bootup logo → Select just “Custom 224-color Linux logo”.
 
In kernel don’t exists “Custom 224-color Linux logo” ( CONFIG_LOGO_CUSTOM_CLUT224 )
In BSP 5.x all works OK
How add  Splash Screen on the Linux Kernel  6.2 ?
             
            
              
                
            
           
          
            
            
              I rename logo_custom_clut224.ppm 800x480  to logo_linux_clut224.ppm
             
            
              
            
           
          
            
            
              Dear @Marius ,
Thanks for sharing this issue with us. Also, glad to hear that you could get it working on your platform.
Regarding this: We are currently working on improving the documentation of the custom splash screen for BSP 6.2.
In the meantime, may I ask you to mark your answer as a solution for this topic (if it is solved)?
             
            
              
            
           
          
            
            
              the solution is a bit imperfect:
             
for BSP 5.x was this solution  (my thread too)
  
  
    My platform IRIS 2.0 + IMX8X + LVDS display 
I have in kernel CONFIG_LOGO_CUSTOM_CLUT224 and my custom logo_custom_clut224.ppm 
Dooring boot I see my splash screen but on bottom screen I see few lines with kernel messages 
How to disable  kernel messages on splash screen
   
 
but on 6.2 this solution doesn’t work
perfect solution for me will be Splash screen on u-boot ,  I can’t do it,  I don’t know anyone who can do that on imx8x
             
            
              
            
           
          
            
            
              Dear @MariusM ,
Sorry about the delayed reply.
             
            
              
            
           
          
            
            
              Hi @Marius ,
I could finally reproduce the issue. I was able to disable/silence the kernel messages using the following command on u-boot:
 setenv setup 'setenv setupargs console=${console},${baudrate} consoleblank=0 earlycon'
Could you please give it a try and let me know how that goes
