luci-app-attendedsysupgrade expects images to be named 'combined-efi' when the system is using EFI images. This came about as x86 has 'combined' images for legacy (BIOS) boot and 'combined-efi' for EFI systems. armsr images were originally named 'combined' only as there was no 'legacy' image type. To avoid special handling in the attendedsysupgrade code, name EFI images consistent with other targets.

This target generates images that can be used on ARM machines with EFI
support (e.g EDKII/TianoCore or U-Boot with bootefi).
There are two subtargets:
- armv7 for 32-bit machines
- armv8 for 64-bit machines
The kernel and filesystem images can also be used directly by QEMU:
Run with qemu-system-arm
# boot with initramfs embedded in
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armsr-armv7-generic-initramfs-kernel.bin
# boot with accel=kvm
qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel
openwrt-armsr-armv7-generic-initramfs-kernel.bin
# boot with a separate rootfs
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armsr-armv7-generic-kernel.bin \
-drive file=openwrt-armsr-armv7-generic-ext4-rootfs.img,format=raw,if=virtio -append 'root=/dev/vda rootwait'
# boot with local dir as rootfs
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armsr-armv7-generic-kernel.bin \
-fsdev local,id=rootdev,path=root-armsr/,security_model=none \
-device virtio-9p-pci,fsdev=rootdev,mount_tag=/dev/root \
-append 'rootflags=trans=virtio,version=9p2000.L,cache=loose rootfstype=9p'
Run with kvmtool
# start a named machine
lkvm run -k openwrt-armsr-armv7-zImage -i openwrt-armsr-armv7-rootfs.cpio --name armsr0
# start with virtio-9p rootfs
lkvm run -k openwrt-armsr-armv7-zImage -d root-armsr/
# stop "armsr0"
lkvm stop --name armsr0
# stop all
lkvm stop --all
The multi-platform ARMv8 target can be used with QEMU:
qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic \
-kernel openwrt-armsr-armv8-generic-initramfs-kernel.bin \
With a EDKII or U-Boot binary for the QEMU ARM virtual machines, you can use these
images in EFI mode:
32-bit:
gunzip -c bin/targets/armsr/armv7/openwrt-armsr-armv7-generic-ext4-combined-efi.img.gz > openwrt-arm-32.img
qemu-system-arm -nographic \
-cpu cortex-a15 -machine virt \
-bios bin/targets/armsr/armv7/u-boot-qemu_armv7/u-boot.bin \
-smp 1 -m 1024 \
-device virtio-rng-pci \
-drive file=openwrt-arm-32.img,format=raw,index=0,media=disk \
-netdev user,id=testlan -net nic,netdev=testlan \
-netdev user,id=testwan -net nic,netdev=testwan
64-bit:
gunzip -c bin/targets/armsr/armv8/openwrt-armsr-armv8-generic-ext4-combined-efi.img.gz > openwrt-arm-64.img
qemu-system-aarch64 -nographic \
-cpu cortex-a53 -machine virt \
-bios bin/targets/armsr/armv8/u-boot-qemu_armv8/u-boot.bin \
-smp 1 -m 1024 \
-device virtio-rng-pci \
-drive file=openwrt-arm-64.img,format=raw,index=0,media=disk \
-netdev user,id=testlan -net nic,netdev=testlan \
-netdev user,id=testwan -net nic,netdev=testwan
One can obtain other EFI/BIOS binaries from:
- Distribution packages (such as qemu-efi-arm and qemu-efi-aarch64 in Debian)
- Community builds, like retrage/edk2-nightly: https://retrage.github.io/edk2-nightly/
