I’m trying to run linux on qemu, especially the versatile version.
I downloaded qemu and linux from github. (qemu : https://github.com/qemu/qemu.git, linux : https://github.com/torvalds/linux.git)
I think these two repositorys are the main project of them.
Anyway, I compiled linux with 2 steps.
- make ARCH=arm versatile_defconfig
- make all ARCH=arm CROSS_COMPILE=arm-none-eabi-
Also compiled qemu with 3 steps.
- ./configure
- make
- sudo make install
And I ran it with this command:
../qemu/arm-softmmu/qemu-system-arm -M versatilepb -m 128M -kernel ./arch/arm/boot/zImage
And a window popped up with just a black screen. What should I do after that?

To mount the root filesystem, I downloaded busybox. (I’m not sure, but this busybox is the mostly used filesystem to develper when they want to make simple enviroment)
I downloaded busybox and i followed some steps.
- wget http://www.busybox.net/downloads/busybox-1.24.1.tar.bz2
- tar -xvf busybox-1.24.1.tar.bz2
- cd busybox-1.24.1/
- make defconfig
- make menuconfig (to make binary as static not shared)
- make -j8
- make install
- cd _install
- find . | cpio -o –format=newc > ../rootfs.img
- cd ..
- gzip -c rootfs.img > rootfs.img.gz
So, my final command is
../qemu/arm-softmmu/qemu-system-arm -M versatilepb -kernel ./arch/arm/boot/zImage -nographic -dtb arch/arm/boot/dts/versatile-pb.dtb -initrd ../rootfs.img.gz -append "root=/dev/ram0 initrd=/bin/sh"
I ran linux on qemu especially versatile version
here is my current status of file with ‘ls’ command
To run the upper command, the linux, qemu and filesystem images should be located like this (except other projects like FreeRTOS it’s only for my situation)
