Avoid black screen between boot splash and bootanimation

andrzejdziedzic — Fri, 04 Nov 2016 10:55:07 GMT

Hi all

I prepared a custom boot splash screen (replaced the "tux" image in drivers/video/logo). Also I prepared a custom bootanimation. The problem is that the splash is visible only few seconds, then screen is cleared and after some time the bootanimation is show.

How to avoid this issue, so switch from boot splash to the bootanimation without clearing the screen?

Android M6.0.1_2.0.0, custom HW based on Sabre AI.

Hi Andrzej

screen may be cleared since kernel reinitializes ipu drivers, so one can

look at uboot patches to avoid IPU and display reinitialization in kernel:

Hi Igor

Unfortunately those patches don't support the MIPI, so I can't use it.

Is there any possibility to intialize IPU and display at the beginning of init? (so do don't wait until SurfaceFlinger starts).
