Introduction

This document provides the guideline to build UEFI firmware for Ampere Computing's Arm64 reference platforms.

Platform code is located under Platform/Ampere/{Platform Name}Pkg.

Silicon code is located under Silicon/Ampere/Ampere{SoC Name}Pkg.

Build machines

  • x86 Linux host machines running latest Ubuntu or CentOS releases.
  • Arm64 Linux host machines if native compiling. This has been tested on Ampere's eMAG and Altra hardware platforms with latest AArch64 CentOS or Ubuntu releases.

How to build (Linux Environment)

Please follow top-level Readme.md for build instructions.

Additional build tools

Ampere provides additional tools and documentation for automating the manual process described as described in the top-level README.md, and for building a final Tianocore UEFI image that can be flashed onto the target system.

To use these tools, clone the following to the WORKSPACE location:

$ git clone https://github.com/AmpereComputing/edk2-ampere-tools.git

Notes

If you run into any build issue with the Intel ASL+ Optimizing Compiler/Disassembler (IASL) that comes with your Linux distro, download and install the IASL compiler from https://acpica.org/. At the time of this write-up, we have tested with version 20200110.

$ wget https://acpica.org/sites/acpica/files/acpica-unix2-20200110.tar.gz
$ tar xzf acpica-unix2-20200110.tar.gz
$ cd acpica-unix2-20200110
$ make HOST=_CYGWIN && sudo make install
