I am trying to setup a splash screen on Uboot and in kernel bootup.
As for the Kernel:
I followed the steps on how to set my splash screen. I deactivated the console FB since I don’t need it. Actually I want to get rid of it so that came as a bonus.
Although, my image did not appear. The screen just goes black (backlight on) and chromium appears when my service deploys it as normal. I activated the option in menuconfig as well (Custom logo 224 ascii .ppm) but I can never see the splash screen. Did I miss anything?
As for the UBoot
I noticed in another question that I had to set the env. variable “panel” to disable autodetect (which was wrong for my display). I got it right: wvga-rgb (800x480). Unfortunately, the backlight does not even turn on - not even a toradex splash screen like I used to get in hdmi monitor.
Do I need to turn on backlight in UBoot? How do I do it? I am connected using the Unif. Touch Display port.
Another question: Can I change uboot configurations in yocto? I would like to set some uboot environmental variables through yocto and change the splash screen in it too.
