Current limitations:
- Only cold boot is supported
- No build instructions for QEMU\_EFI.fd and rootfs-arm64.cpio.gz
``QEMU_EFI.fd`` can be dowloaded from
Getting non-TF images
---------------------
``QEMU_EFI.fd`` can be downloaded from
http://snapshots.linaro.org/components/kernel/leg-virt-tianocore-edk2-upstream/latest/QEMU-KERNEL-AARCH64/RELEASE_GCC5/QEMU_EFI.fd
or, can be built as follows:
.. code:: shell
git clone https://github.com/tianocore/edk2.git
cd edk2
git submodule update --init
make -C BaseTools
source edksetup.sh
export GCC5_AARCH64_PREFIX=aarch64-linux-gnu-
build -a AARCH64 -t GCC5 -p ArmVirtPkg/ArmVirtQemuKernel.dsc
````
Then, you will get ``Build/ArmVirtQemuKernel-AARCH64/DEBUG_GCC5/FV/QEMU_EFI.fd``
Please note you do not need to use GCC 5 in spite of the environment variable
``GCC5_AARCH64_PREFIX``
The rootfs can be built by using Buildroot as follows:
.. code:: shell
git clone git://git.buildroot.net/buildroot.git
cd buildroot
make qemu_aarch64_virt_defconfig
utils/config -e BR2_TARGET_ROOTFS_CPIO
utils/config -e BR2_TARGET_ROOTFS_CPIO_GZIP
make olddefconfig
make
Then, you will get ``output/images/rootfs.cpio.gz``.
