How to run Linux on a QEMU ARM Versatile machine?


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.

  1. make ARCH=arm versatile_defconfig
  2. make all ARCH=arm CROSS_COMPILE=arm-none-eabi-

Also compiled qemu with 3 steps.

  1. ./configure
  2. make
  3. 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?


Solution

  • I downloaded qemu and linux from github repositories.

    Anyway, I compiled Linux with 2 steps.

    1. make ARCH=arm versatile_defconfig
    2. make all ARCH=arm CROSS_COMPILE=arm-none-eabi-

    Also compiled qemu with 3 steps.

    1. ./configure
    2. make
    3. sudo make install

    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 these steps.

    Download and extract

    wget http://www.busybox.net/downloads/busybox-1.24.1.tar.bz2
    tar -xvf busybox-1.24.1.tar.bz2
    

    Install

    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)
