Dear support team,
We are about switching a custom yocto build from Kirkstone to Scarthgap release. We’ve been able to migrate successfully but still have a delay during boot until Framebuffer / dpu-core is available.
With kirkstone, the dpu-core was loaded after about 1.8s and framebuffer was available after 2.1s.
Now with scarthgap, the dpu-core is loaded after 8.3s.
I’ve also tried to use plymouth and initramfs but wasn’t able to solve the problem (because the graphic drivers also we’re not available there). I would like to solve the issues without initramfs - if possible.
Following the dmesg-output until framebuffer is available (for scarthgap). Also below a part of my dts file for configuring the display.
