Depending how recent the card is, you might need to implement UEFI & GOP instead. Might be better approach to read any open source driver code on Linux or BSD to find out how to get basic framebuffer
- ymz5 4mo agoExactly. After days of unsuccessful VideoBIOS bring-up (via U-Boot's emulator), I gave up, and implemented exactly what you suggested: graphics mode, using of course parts of nouveau. Claude Code is smart in extracting information. And it worked!! Now I have the picture on the monitor when U-Boot starts. The only one drawback: it takes 30..40 seconds between the moment of machine-power-on and the picture on the screen.
