# Introduction
These instructions explain how to get an edk2/edk2-platforms build running
-on the ARM Base FVP, which is a software model provided by ARM (for free)
+on the Arm Base FVP and a Juno. The Arm Base FVP is a software model provided
by ARM (for free)
, which models a Cortex A core with various peripherals. More information
-can be found here:
-[https://developer.arm.com/products/system-design/fixed-virtual-platforms]
+can be found
[here](https://developer.arm.com/products/system-design/fixed-virtual-platforms).
-##Requirements
-- A 32-bit or 64-bit Linux host machine.
+## Build environment setup on Linux or Windows
-# Build EDK2 TianoCore
+### Initial steps
-`build -a AARCH64 -p Platform/ARM/VExpressPkg/ArmVExpress-FVP-AArch64.dsc -t GCC5`
+The first step towards building an EDKII firmware image is to create a working
directory.
-Once built, the edk2 image is the following file Build/ArmVExpress-FVP-AArch64/DEBUG_GCC5/FV/FVP_AARCH64_EFI.fd
+1. Launch a terminal window.
+2. Create a directory on your development machine (we willl name it 'source'
in this example).
+3. Set the WORKSPACE environment variable to point to this directory.
-# Run edk2/edk2-platforms on the ARM Base Platform FVP
+#### Example:
+In a Linux bash shell:
+```
+cd <Directory where you want to work>
+mkdir source
+cd source
+export WORKSPACE=$PWD
+```
-In order to run the binary we have just built there are a few steps we need to
-go through, we need to get a model, a set of prebuilts (where we will swap out
-the edk2 image with our own) and the tool with which we will swap out the
-prebuilt edk2 image.
+OR
-We will also rely on the "run_model" script that comes with the prebuilts, it
-is entirely possible to run the model without this but would require quite a
bit
-of knowledge regarding the arguments of the ARM fastmodel (documentation can
be found here:
-[https://developer.arm.com/docs/100966/1101/programming-reference-for-base-fvps/base-platform-revc-features])
-however the manual set of the FVP is outside the scope of this document. If
you are interested
-please consult the documentation.
+In a Windows command prompt:
-It's recommended you create a folder where you download the prebuilts and
-required tool and copy your edk2 image in to it, as the run script expects
-the binaries in the same directory.
+```
+cd <Directory where you want to work>
+mkdir source
+cd source
+set WORKSPACE=%CD%
+```
-1. Download the Base FVP from here https://developer.arm.com/products/system-design/fixed-virtual-platforms
+### Cloning the source code repositories
- - Select Armv8-A Base Platform FVP based on Fast Models 11.4
- - It has a click through license but is free.
+Note: To clone the repositories you need 'git' to be installed on your
development PC (see Development Tools).
-2. Download the 20.01 Linaro ARM Landing Team release for FVP booting UEFI
-https://releases.linaro.org/members/arm/platforms/20.01/fvp-uefi.zip
+In the terminal window, change directory to your workspace ('source') folder
and run the following commands. Install Git if necessary.
-3. Clone the trusted firmware repo from https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
+```
+git clone https://github.com/tianocore/edk2.git
+git clone https://github.com/tianocore/edk2-platforms.git
+git clone https://github.com/acpica/acpica.git
+```
-4. Build fiptool: `make -C trusted-firmware-a/tools/fiptool`
+Then go to the edk2 folder and update the submodules.
-5. Update the fip.bin image from fvp-uefi.zip by running the following command:
+```
+cd edk2
+git submodule update --init
+cd ..
+```
- `./trusted-firmware-a/tools/fiptool/fiptool update --nt-fw=[path to binary built above] fip.bin`
+# Building firmware on a Linux host
-6. Execute the FVP run_model.sh script from fvp-uefi.zip and provide a path to the FVP binaries
-downloaded in step 1):
+## Prerequisites
- `MODEL=[path to FVP binary] ./run_model.sh`
+- A 64-bit development machine.
+- Ubuntu 20.04 desktop.
+- At least 10GB of free disk space.
-This expects the contents of fvp-uefi.zip, the bl1.bin and fip.bin (which is
-the file we modify), to be in the same directory as the run_model.sh script.
+Check the Ubuntu version by typing the following in the terminal window.
-This should be sufficient to provide a build/run/debug environment for aarch64.

+
+| Sr. No. | Tool | Description
| Install instructions
|
+|-----------|----------------------------------------------|--------------------------------------------------------------|----------------------------------------------------------|
+| 1 | Python 3 | Python interpreter | Go
[here](https://www.python.org/downloads/windows/) <br> <br> Choose the latest Python 3.X release. <br>
<br> Download and run the Windows x86_64 MSI installer <br> <br> If needed, add the python executable to your
path by executing the following command: <br> > set PATH=<Path_to_the_python_executable>;%PATH% |

Tools <br> <br> Extract the content and place it at C:\ASL\ <br> <br> Check that the compiler is at
the right place by executing: <br> > C:\ASL\iasl.exe -v |
+| 4 | Microsoft Visual Studio 2019 Professional | Microsoft IDE and compiler
toolchain. | Go
[here](https://visualstudio.microsoft.com/downloads/) <br> <br> Download and
install Visual Studio 2019 Professional |
+| 5 | echo tool | Echo
| See Workaround for echo command
below. |
+
+
+## Setting up the development tools
+
+Install the required development tools listed above by running the appropriate
installer applications.
+
+### Arm cross compiler toolchain
+The Arm toolchain Windows (i686-mingw32) hosted cross compilers are available
[here](https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads).
+
+Select the latest toolchain for 'AArch64 bare-metal target (aarch64-none-elf)'
GCC cross compiler.
+
+Example: Download arm-gnu-toolchain-12.2.rel1-mingw-w64-i686-aarch64-none-elf
+
+Create a directory called 'toolchain' under the workspace directory and
extract the toolchain to this directory using the downloaded installer.
+
+The toolchain folder tree should look as below:
+
+```
+toolchain
++---arm-gnu-toolchain-12.2.rel1-mingw-w64-i686-aarch64-none-elf
+| +---aarch64-none-elf
+| +---bin
+| +---include
+| +---lib
+| +---libexec
+| +---share
+```
+
+### Workaround for the echo command
+
+EDKII needs a workaround related to the echo command. A script replacing the
Windows echo executable must be created, with the name "echo.BAT?:
+
+- Create a file named "echo.BAT" in the folder of your choice.
+- Paste the following lines inside the file:
+
+```
+rem %~f0 echo.BAT %*
+rem This file exists to overcome a problem in the EDKII build where
+rem build_rule.template invokes a command as:
+rem "$(OBJCOPY)" $(OBJCOPY_FLAGS) ${dst}
+rem When OBJCOPY is set to echo, this results in the following error:
+rem "echo" objcopy not needed for m:\...\PCD\Dxe\Pcd\DEBUG\PcdDxe.dll
+rem And CMD.EXE fails to find the DOS echo command because of the quotes
+@echo %*
+@goto :EOF
+```
+
+- Add the file to your PATH by executing:
+```
+> set PATH=<Path_to_the_echo_file>;%PATH%
+```
+
+## Building EDKII firmware
+
+1. To build the firmware image, follow the steps below and run the commands in
the terminal window.
+2. Set up the environment variables.
+
+```
+ set
GCC5_AARCH64_PREFIX=%WORKSPACE%\toolchain\arm-gnu-toolchain-12.2.rel1-mingw-w64-i686-aarch64-none-elf\bin\aarch64-none-elf-
+ set PACKAGES_PATH=%WORKSPACE%\edk2;%WORKSPACE%\edk2-platforms
+ set EDK_TOOLS_PATH=%WORKSPACE%\edk2\BaseTools
+ set GCC_HOST_BIN=n
+```
+
+Select the python version you wish to use and set the PYTHON_COMMAND
environment variable to your Python executable.
+
+Set the PYTHON_COMMAND to point to the Python3 executable.
+
+Check that your path is set up as it is stated in the development tools table
above. It should give access to:
+
+- The make executable
+- The echo.BAT script
+
+3. Configure the EDKII development environment by running the edksetup.bat
script.
+The Rebuild option can be skipped if the BaseTools have already been built.
+
+The ForceRebuild option can be used to do a clean build of the Base tools.
+```
+> call %WORKSPACE%\edk2\edksetup.bat [Rebuild | ForceRebuild]
+```
+
+### Build the firmware for Arm FVP Base AEMv8A-AEMv8A Model platform
+
+Run the following command to build the firmware for FVP Base AEMv8A-AEMv8A
platform.
+
+```
+> build -a AARCH64 -t GCC5 -p Platform\ARM\VExpressPkg\ArmVExpress-FVP-AArch64.dsc
-b < DEBUG | RELEASE >
+```
+
+The firmware binaries can be found at the following location:
