Today I follow the nix.dev tutorial again.
This time I also updated the bootloader, using the Raspberry Pi Imager method.
The screen kept flashing/flickering.
What I changed:
- rpi4 4gb & rpi4 2gb
- 5 hdmi-microhdmi cables
- 3 psu
- 2 sd-card & 4 usb-sata adapters & 6 ssd
The older Nixos image worked without flashing: https://hydra.nixos.org/build/134720986/download/1/nixos-sd-image-21.03pre262561.581232454fd-aarch64-linux.img.zst
The Raspberry Pi OS worked without flashing.
1 Last change, The TV:
- Loewe Art 32, keeps flashing.
Now I tried with a recent Medion TV. It works.
I don’t know why… Older hdmi spec ?
tldr: The tv is the cause of all these problems.
