Install QEMU for 64-bit Windows 10
- Go to the following web site https://www.qemu.org/download/ and download the latest QEMU installer for Windows 64bit.
- Run the installer.
The QEMU executable files are installed, e.g. C:\Program Files\qemu\
- Go to the following web site https://github.com/dhruvvyas90/qemu-rpi-kernel and download a suitable kernel, e.g. kernel-qemu-4.4.34-jessie.
- Place the kernel file in a folder e.g. D:/Temp/raspbian/kernel-qemu-4.4.34-jessie
- Go to the following web site http://downloads.raspberrypi.org/raspbian/images/ and download the latest image e.g. 2019-06-20-raspbian-buster.zip
- Unzip the image file into a folder, e.g. D:/Temp/raspbian/2019-06-20-raspbian-buster.img
- Run a text editor.
- Type in the following lines.
"c:\Program Files\qemu\qemu-system-arm.exe" ^
-kernel kernel-qemu-4.4.34-jessie ^
-cpu arm1176 ^
-m 256 ^
-M versatilepb ^
-serial stdio ^
-append "root=/dev/sda2 rootfstype=ext4 rw" ^
-hda 2019-06-20-raspbian-buster.img ^
-net nic ^
-net user,hostfwd=tcp::5022-:22 ^
-no-reboot
Note: rename the kernel and image file names (in bold) to match the downloaded file names accordingly.
- Save as a bat file e.g. run_raspbian.bat and close the editor.
- Open up a Command Prompt.
- Change directory to the folder containing the kernel and image files e.g. D:/Temp/raspbian.
- Type in the command:
D:\> run_raspbian.bat
The QEMU window appears running Raspbian OS

Thank you for this tutorial!
You absolutely ROCK for this tutorial. In my case I had to add the -dtb parameter with the compiled device tree. After that, the latest Buster release cranked right on up. Thank you VERY much for this! -- Chuck
you are the Best akmost ,all other Tutorials are outdated

Hi,
Do you know how to configure this to emulate raspi 3B+?
Thanks
dominoc925, it says this:

Hi @ThatAverageCodist, for the latest kernel you have to download versatile-pb-buster.dtb from the kernel repo https://github.com/dhruvvyas90/qemu-rpi-kernel
Hi, thanks for this!
I assume changing "-m 256 ^" for "-m 1024 ^" will set 1GB of ram, is it true?
In the other hand, how can I set e.g. 10 or 15 GB for disk usage?
Hi @Felipe Arce, yeah -m defaults to mega but you can use optional suffix k, M, G, T, P or E means kilo-, mega-, giga-, tera-, peta-and exabytes for clarity too.
I'm not sure whether I can change the allocated Raspbian disk image usage size; I would think you'd need to add in another disk image. Needs some investigation.
@dominoc925 I just tried to asign more ram, but it seems that it is not posible because versatilepb board is limited to 256MB RAM. You know how to avoid this?
Hello, my update config:

Hello, can you explain how I can configure a network in qemu with Windows 10?
You'll have to add dtb file asking with the kernel and invoke in the qemu command
"c:\Program Files\qemu\qemu-system-arm.exe" -kernel kernel-qemu-4.4.34-jessie -cpu arm1176 -m 256 -M versatilepb -serial stdio -append "root=/dev/sda2 rootfstype=ext4 rw" -hda 2020-02-05-raspbian-buster.img -dtb versatile-pb-buster.dtb -net nic -net user,hostfwd=tcp::5022-:22 -no-reboot
The system cannot find the path specified.
Hey i'm facing this issue , can anyone tell me whats wrong . I tried checking the path . Its all correct.
? @Unknown, at first glance, the command line seems fine. Try troubleshooting the options.
Are you able to run the qemu-system-arm.exe by itself - that should print out some help messages. If so, add in more options and run again.
I want to emulate latest raspbian (2020-08-20-raspios-buster-armhf.img).i want to use 5.4 kernel.
what will be the command for version 5.4 kernel?
This is my batch file:
"c:\Program Files\qemu\qemu-system-arm.exe" ^
-kernel kernel-qemu-5.4.51-buster ^
-cpu arm1176 ^
-m 256 ^
-M versatilepb ^
-serial stdio ^
-append "root=/dev/sda2 rootfstype=ext4 rw" ^
-hda 2020-08-20-raspios-buster-armhf-lite.img ^
-dtb versatile-pb-buster.dtb ^
-net nic ^
-net user,hostfwd=tcp::5022-:22 ^
-no-reboot

Hello,
Did anyone find a way to increase the ram for buster?
