Is there a decent hardware manual even for the first VisionFive, say to the extent the original BeagleBoards had one (even if the Pis never did)? I wanted to write a (slow) emulator that could at least boot the Ubuntu image into text mode, but I have absolutely no idea how it all hangs together beyond the SoC docs. For that matter, the page for the Unmatched doesn’t have a link to a hardware manual either.
