Hi, All,

 

Please find attached the patch to enable splash screen in U-boot for SEIKO LCD(IMX28 LCD) on I.MX6SL EVK.

 

Hope it will be helpful.

 

Best Regards,

Hi All,

we used the attached patch(fsl_mcimx6sl_lcd_splash.patch.zip) to enable splash screen in U-boot for SEIKO LCD(IMX28 LCD) on I.MX6SL EVK.

we are getting freesacle logo correctly at the time of uboot booting,but at the time of kernel  booting blank white screen in coming on the display and from the logs we are getting:

   "Unable to handle kernel NULL pointer dereference at virtual address 00000010"

check below for the logs :
