- Summarizing the problem
Can't identify a needed display module which is loaded within the initramfs on boot time.
- Providing details and any research
After fixing the problem on the surface using Ingos's answer from here (https://raspberrypi.stackexchange.com/a/112429/118556) I know need a process to identify and "restrict" the correct module on boot time.
My Raspberry is a Pi 4 Modell B; 4 GB, ARM-Cortex-A72 4 x, 1,50 GHz, 4 GB RAM, WLAN-ac, Bluetooth 5, LAN, 4 x USB, 2 x Micro-HDMI with a Raspian Buster. Installed is LVM, Pi-hole Wireguard. The display is a Bruphny 4.0 (https://www.amazon.de/gp/product/B07XPM2ZS3).
- Describing what I’ve tried
Tried to understand how and where Ingo has learned such a deep understanding from Linux OS.
