Booting in QEMU


These instructions require QEMU 5.2 or later.


Make sure to set the FIOCTL_FACTORY environment variable:
export FIOCTL_FACTORY=<factory>
  1. List available Targets and decide on which to boot:

    fioctl targets list
  2. Make a directory for the artifacts and cd into it:

    mkdir -p lmp-qemu/arm64
    cd lmp-qemu/arm64
  3. Download the artifacts needed for arm64, replacing <target_number> with the target you would like to boot:

    # Download and extract the Factory image
    fioctl targets artifacts <target_number> qemuarm64-secureboot/lmp-factory-image-qemuarm64-secureboot.wic.gz | gunzip > lmp-factory-image-qemuarm64-secureboot.wic
    # Download ATF + OP-TEE + U-Boot binary
    fioctl targets artifacts <target_number> qemuarm64-secureboot/flash.bin > flash.bin
  4. The directory tree should now look like this:

    └── arm64
        ├── lmp-factory-image-qemuarm64-secureboot.wic
        └── flash.bin
  5. Run the QEMU script below against the artifacts inside of lmp-qemu/. You can save this as inside the directory for convenience.


The QEMU CLI passes the necessary flags and parameters to the appropriate qemu-system command. This includes path to the image, CPU, network, and other device information. For specifics, consult QEMU’s Documentation.

Booting Graphically

In order to boot QEMU with an OpenGL capable virtual GPU (required for Wayland/Weston), add the following flags to the QEMU CLI:

-display gtk,gl=on -device virtio-gpu-pci

Do not copy the -nographic flag at the end of the QEMU CLI below.


qemu-system-aarch64 -m 1024 -cpu cortex-a57 -no-acpi -bios flash.bin \
   -device virtio-net-device,netdev=net0,mac=52:54:00:12:35:02 -device virtio-serial-device \
   -drive id=disk0,file=lmp-factory-image-qemuarm64-secureboot.wic,if=none,format=raw \
   -device virtio-blk-device,drive=disk0 -netdev user,id=net0,hostfwd=tcp::2222-:22 \
   -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-pci,rng=rng0 \
   -chardev null,id=virtcon -machine virt,secure=on -nographic


To access QEMU via SSH, append these parameters to the QEMU CLI command above:

-netdev user,id=net0,hostfwd=tcp::2222-:22

Then, run SSH with:

ssh -p 2222 fio@localhost
