Booting in QEMU¶
Warning
These instructions require QEMU 5.2 or later.
List available Targets and decide on which to boot:
Note
Make sure to set the FIOCTL_FACTORY environment variable:
export FIOCTL_FACTORY=<factory>
Make a directory to store the artifacts and
cd
into it.mkdir -p lmp-qemu/arm cd lmp-qemu/arm
Download the necessary artifacts for arm, replace
<target_number>
with the target you would like to boot# Download and extract the Factory image fioctl targets artifacts <target_number> qemuarm/lmp-factory-image-qemuarm.wic.gz | gunzip > lmp-factory-image-qemuarm.wic # Download ATF + OP-TEE + U-Boot binary fioctl targets artifacts <target_number> qemuarm/other/u-boot-qemuarm.bin > u-boot-qemuarm.bin
The directory tree should now look like this
lmp-qemu/ └── arm ├── lmp-factory-image-qemuarm.wic └── u-boot-qemuarm.bin
Run the QEMU script below against the artifacts inside of
lmp-qemu/
. You may want to save this asrun.sh
inside the directory for convenience
Booting Graphically¶
In order to boot QEMU with an OpenGL capable virtual GPU inside (required for Wayland/Weston), the following flags need to be added to the QEMU CLI:
-display gtk,gl=on -device virtio-gpu-pci
The -nographic
flag must also be removed from the QEMU CLI.
QEMU CLI¶
qemu-system-arm -machine virt,highmem=off -cpu cortex-a7 -m 1024M \
-bios u-boot-qemuarm.bin \
-serial mon:vc -serial null \
-drive id=disk0,file=lmp-factory-image-qemuarm.wic,if=none,format=raw -device virtio-blk-device,drive=disk0 \
