To all experts in video cards reading this:
Do you know, how to initialize a NVidia card in the RISC-V system (such as Unmatched or Polarfire) to the basic VGA mode 3 (text mode, 80x25)? :)
I really wanted to get the Real Console for QSOE, but so far all my efforts to run video BIOS (via U-Boot's bios_emulator) are not successful...
- p_l 3mo agoDepending 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 3mo 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.
