Raspberry Pi Stack Exchange is a question and answer site for users and developers of hardware and software for Raspberry Pi. It only takes a minute to sign up. Complete beginner question: why do I have to pass an extra kernel binary when running e. So far all the documentations state that the image files are the equivalent of a mass storage device, so if not the bootloader but at least a kernel should be present in them, no? If Qemu simulates a CPU, shouldn't this somehow even require a start from the very beginning, i.

As this is on a headless server if I don't specify -nographic it just errors Could not initialize SDL No available video device - exiting. I tried a couple of times as it seemed a bit strange really. I also retried it with my original command and that one still hangs at the same place one line earlier, just after SSH. I also double checked the full image as downloaded from raspberrypi.
