Qemu

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\
