FVPs are fixed configurations of ARM Fast Models; they are also known as RTSMs (Real Time System Models). The Base FVP is an evolution of the VE (Versatile Express) RTSM.
+While the AArch64 Foundation FVP is free to download, the Base FVP requires an ARM license. The Base FVP has additional debugging and configuration features. + +Requirement: +* A 32-bit or 64-bit Linux host machine. Support for MS Windows-based toolchains has not been added to the EDK2 BaseTools. + +== Getting the EDK2 Source with AArch64 support (ARM 64-bit architecture) == +1) Get the requirements + +A Universally Unique Id (UUID) header. Needed to build the EDK2 BaseTools. On Ubuntu: sudo apt-get install uuid-dev + +2) Download the sources + +Please see the root edk2/Readme.md for information on how to obtain the source + +== Build EDK2 Tianocore == + +1) Install AArch64 GNU toolchain: +
sudo apt install gcc-aarch64-linux-gnu
+ +2) Build EDK2: + +
cd $(WORKSPACE)/edk2
+* For the Foundation and Base FVPs (defined by the DSC file ArmPlatformPkg?/ArmVExpressPkg/ArmVExpress-RTSM-AEMv8Ax4-foundation.dsc): +
GCC5_AARCH64_PREFIX=aarch64-linux-gnu- build -a AARCH64 -p Platform/ARM/VExpressPkg/ArmVExpress-FVP-AArch64.dsc -t GCC5
+ +Once built, the UEFI Firmware is the following file Build/ArmVExpress-FVP-AArch64/DEBUG_GCC5/FV/FVP_AARCH64_EFI.fd + +Note 1: To build the release build, add '-b RELEASE'. Here's an example with the Foundation FVP: +
GCC5_AARCH64_PREFIX=aarch64-linux-gnu- build -a AARCH64 -p Platform/ARM/VExpressPkg/ArmVExpress-FVP-AArch64.dsc -t GCC5 -b RELEASE
+ +== Start Linux from UEFI on the FVPs == + +=== Build AArch64 Linux === +1) Get the AArch64 Linux sources +
git clone git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64.git -b soc-armv8-model
+cd linux-aarch64
+ +2) Build the AArch64 kernel with Virtio support +
make ARCH=arm64 mrproper
+make ARCH=arm64 defconfig
+ +Enable Virtio Disk and Ext4 support in the kernel. The Linaro disk file-system uses Ext4. +
make ARCH=arm64 menuconfig
+Device Drivers  ---> Virtio drivers  ---> <*> Platform bus driver for memory mapped virtio devices
+Device Drivers  ---> [*] Block devices  --->  <*> Virtio block driver
+File systems  ---> <*> The Extended 4 (ext4) filesystem
+ +Build the kernel. +
make -j4 ARCH=arm64 CROSS_COMPILE=/gcc-linaro-aarch64-linux-gnu-4.8-2013.06_linux/bin/aarch64-linux-gnu-
+ +You should get the binaries: +* arch/arm64/boot/Image +* arch/arm64/boot/dts/foundation-v8.dtb +* arch/arm64/boot/dts/rtsm_ve-aemv8a.dtb + +=== Run Linux from UEFI on the Foundation FVP === + +1) Download the Foundation FVP: http://www.arm.com/fvp + +Decompress the AArch64 Foundation FVP +
tar xf ~/FM000-KT-00035-r0p8-48rel5.tgz
+ +2) The current version of the Foundation FVP can only start an ELF image. To workaround this limitation, we use the 'uefi-aarch64-bootstrap' to start the UEFI image on this model. + +To build the 'uefi-aarch64-bootstrap': +
pushd ArmPlatformPkg/ArmVExpressPkg/Scripts/uefi-aarch64-bootstrap/
+CROSS_COMPILE=/gcc-linaro-aarch64-linux-gnu-4.8-2013.06_linux/bin/aarch64-linux-gnu- make
+popd
+ +3) The Foundation FVP takes an option for an ELF file to be loaded as well as an option to load a binary data blob into RAM. + +Linux kernel (filename = 'Image') and the Device Tree Binary (filename = 'foundation-v8.dtb') are expected to be found in the directory where the model is started from. + +A file system example can be downloaded from Linaro: +
wget http://releases.linaro.org/13.06/openembedded/aarch64/vexpress64-openembedded_minimal-armv8_20130623-376.img.gz
+gunzip vexpress64-openembedded_minimal-armv8_20130623-376.img.gz
+ +The file-system needs some minimal preparation: +
mkdir tmp
+fdisk -lu vexpress64-openembedded_minimal-armv8_20130623-376.img
+sudo mount -o loop,offset=$((106496 * 512)) vexpress64-openembedded_minimal-armv8_20130623-376.img tmp/
+cd tmp
+sudo ln -s S35mountall.sh etc/rcS.d/S03mountall.sh
+sudo sh -c "echo 'devtmpfs /dev devtmpfs mode=0755,nosuid 0 0' >> etc/fstab"
+cd ..
+sudo umount tmp/
+ +The following command line can be used to run UEFI in the following manner: +
$AARCH64_FOUNDATION_MODEL_ROOT/Foundation_v8 --cores=2 --image=ArmPlatformPkg/ArmVExpressPkg/Scripts/uefi-aarch64-bootstrap/uefi-bootstrap-el3-foundation.axf --nsdata=Build/ArmVExpress-RTSM-AEMv8Ax4-foundation/DEBUG_GCC47/FV/RTSM_VE_FOUNDATIONV8_EFI.fd@0xA0000000 --block-device=/vexpress64-openembedded_minimal-armv8_20130623-376.img
+ +Note: Do not use a symbolic link to the file-system image. The model will not be able to read the image file. + +=== Run Linux from UEFI on the Base FVP === + +The Linux kernel (filename = 'Image') and the Device Tree Binary (filename = 'rtsm_ve-aemv8a.dtb') are expected to be found in the directory where the model is started from. +
