When booting is finished, you will see a prompt raspberrypi login: drive file=-raspbian-stretch-lite.img,format=raw \ append "rw console=ttyAMA0 root=/dev/sda2 rootfstype=ext4 loglevel=8 rootwait fsck.repair=yes memtest=1" \ dtb raspbian_bootpart/versatile-pb.dtb \ ![]() kernel raspbian_bootpart/kernel-qemu-4.14.50-stretch \ The complete invocation is: $ qemu-system-arm \ This is a convenience option which lets you ssh into the guest using $ ssh -p 5022 localhost The memory card is modeled using -drive file=-raspbian-stretch-lite.img,format=rawįinally, the network is integrated in the board model, but we use the option -redir tcp:5022::22 On MacOS you can just double-click on the image file. In Linux, you can mount the partition following the approach as explained in my Debian tutorial. To get the actual PARTUUID for the Raspbian instance you downloaded, the easiest way is to look in the file cmdline.txt in the boot partition on the image file. If you use exactly the same image as I did then the PARTUUID is ee25660b-02. This is not needed for our use with QEMU but it is if you want to boot from a USB drive, because you can't rely on the name and need the unique partition identifier. PARTUUID means Partition Universally Unique Identifier. In our case, the key option is root=/dev/sda2 which tells the kernel the location of the root partition to be mounted. Note also console=ttyAMA0, the Arm equivalent of console=ttyS0 on Intel machines. If you want a 64bit OS then you need to use qemu-system-aarch64 with the raspi3 type and a 64bit kernel. The kernel and initramfs you can find on the first partition of your SD card or extract from the OS image for a Raspian Pi. On the physical Raspberry Pi, these options can be provided in the cmdline.txt file. qemu-system-arm -machine typeraspi2 -m 1024 -kernel vmlinux -initrd initramfs qemu-system-aarch64 -machine typeraspi3 -m 1024 -kernel vmlinux -initrd initramfs. You can control the log level using loglevel= in the -append string, which contains all options to be passed on to the kernel at boot time. The -serial stdio option redirects the boot output messages and the console to your terminal. The -kernel and -dtb options take the relative paths to the kernel and dtb files. This board model supports at most 256MB of RAM ( -m). We use the versatilepb board model ( -M) and the arm1176 CPU model ( -cpu). With these preparations done, we can boot the Raspbian image on QEMU.
