I am implementing a flawless transition between u-boot splashscreen and Linux configured to use the simple frame-buffer driver.
The transition should not have any blank screen on screen flickering.
Is there already a solution for this?
Partial solutions would also be interesting.
If there is no mode change or resolution change I think it's possible to realize your setup. I need to check in more detail, but I'm rather sure that we as NXP don't have a full solution for this yet.
For some projects we worked on an early splashscreen, but also on skipping it in u-boot and realize an early Linux display enablement.
