Looks like I'll need a real Raspberry Pi for my experiments.

This also explains why X under QEMU is *sooo slow*. The Rpi emulator is the most recently launched Raspberry Pi emulator created to do the Raspbian environment emulation on the Windows system. Essentially it's just drawing into a chunk of memory and handing it to QEMU to draw to the real screen. X works because it's using the standard linux framebuffer, which is a minimal graphics structure in main memory that does no acceleration. That means I'll never get the hardware acceleration I need for testing IdealOS. So what's the deal? Why can X run but not the opengl samples?Īfter further research I've determined that QEMU emulates the main ARM CPU, but *not* the custom graphics chip in the Pi. Then I was able to get X to boot: WHAAA?! So I modified the scripts to use raspbian-buster instead of raspbian-buster-lite, turn off the headless option, then ran the entire process again. These instructions won't give me any graphics because it's using the 'lite' version of Raspbian which doesn't include a desktop and X11. But I could have *sworn* I'd seen QEMU running a Raspbian desktop. I tried running the example command line graphics programs in /vc/opt but they wouldn't work, complaining that it can't access the vchiq. run.sh will run it as a headless instance, giving me a bash shell into a virtual Pi.

The two scripts in this repo get the job done reliably./install.sh willl download QEMU, a Raspbian distro, and all of the required deps. Fortunately the open source emulation tool QEMU is up to the task.įollowing the instructions here, I was able to download and run QEMU on my Mac. That means I need an emulator, not just an OS conatiner wrapper like Docker. The RaspberryPi is an ARM computer and most Macs (until a few months ago) are X86. The short version is: yes it can be done but it's useless for graphics. As part of that I wanted to emulate a Raspberry Pi on my Mac. PowerPC CPU emulator by Gwenole BeauchesneĪnybody have the same experience or any hints on how I can boot SheepShaver from the 9.I've paused my work on Filament for a while to go back and do some more research into low level graphics for IdealOS.

I’ve also tried fiddling with the bootdrive value in sheepshaver_prefs – also no change in behaviour. I’ve tried the “Troubleshooting” hint in the blog of replacing “disk” with “cdrom” in the line which reads “disk /home/pi/mac9x/9.iso” in the file /home/pi/.sheepshaver_prefs – to no avail.
The response is a grey background with a 3.5 floppy icon with flashing question mark “?” – this suggests to me that the emulator is bootstrapping from the ROM ok, but that I am failing to boot from the CDROM ( i.e 9.iso)

I did the OS 7 install with Mini VMac – great fun! Now I am trying to get OS 9 running with SheepShaver per the instructions in the video, but I’m hitting a snag.Įverything follows the video fine until I try to boot from the 9.iso image.
