### Emulating raspberry pi 4
|
|||
|
|
|
|||
|
|
- firstly generate two images
|
|||
|
|
`qemu-img create -f qcow2 arm.img 16G` ~ Image for os
|
|||
|
|
`qemu-img create -f qcow2 varstore.img 64M` ~ EFI varaible store
|
|||
|
|
- then download EFI file (A UEFI image for QEMU’s virt machine type, I use an EDK II derived snapshot image from Linaro)
|
|||
|
|
`http://snapshots.linaro.org/components/kernel/leg-virt-tianocore-edk2-upstream/latest/QEMU-AARCH64/RELEASE_GCC5/QEMU_EFI.img.gz`
|
|||
|
|
|
|||
|
|
- install
|
|||
|
|
`qemu-system-aarch64 \
|
|||
|
|
-cpu cortex-a72 -smp 4 -M virt -m 4096 -nographic \
|
|||
|
|
-drive if=pflash,format=raw,file=QEMU_EFI.img \
|
|||
|
|
-drive if=pflash,file=varstore.img \
|
|||
|
|
-drive if=virtio,file=arm.img\
|
|||
|
|
-drive if=virtio, format=raw, file=file.iso`
|
|||
|
|
- run
|
|||
|
|
`qemu-system-aarch64 \
|
|||
|
|
-cpu cortex-a72 -smp 4 -M virt -m 4096 -nographic \
|
|||
|
|
-drive if=pflash,format=raw,file=QEMU_EFI.img \
|
|||
|
|
-drive if=pflash,file=varstore.img \
|
|||
|
|
-drive if=virtio,file=arm.img\`
