This repository contains instructions and tools to assist in the compilation and final build of Tianocore for Ampere's platforms. It is an extension of what is already provided in the README located at edk2-platforms/Platform/Ampere/README.md

Manual Building

It is assumed that your build environment has been set up appropriately based on edk2-platforms/Platform/Ampere/README.md.

Throughout this document, Ampere's Mt. Jade platform is used to illustrate various steps to arrive at a final Tianocore UEFI image that can be flashed to the platform.

The process of creating a flashable image involves the following steps:

1. Building the UEFI image
2. Signing the UEFI image
3. Integrating Ampere's Arm Trusted Firmware binary and platform's board settings
4. Building the capsule update image that can be used to update Tianocore firmware via fwupdate or fwupd methods.

Building the UEFI image

Building EDK2 FD with the following command:

$ cd edk2-platforms && build -a AARCH64 -t GCC5 -b RELEASE -D SECURE_BOOT_ENABLE -p Platform/Ampere/JadePkg/Jade.dsc

Notes: Please refer to LinuxBoot.md for building EDK2+LinuxBoot FD.

The resulting image will be at

edk2-platforms/Build/Jade/RELEASE_GCC5/FV/BL33_JADE_UEFI.fd

We will be using edk2-platforms/BUILDS/jade_tianocore_atf for the final artifacts.

$ cd edk2-platforms
$ mkdir -p BUILDS/jade_tianocore_atf

Signing the image

You need to download and install cert_create and fiptool from Arm Trusted Firmware.

$ git clone --depth 1 https://github.com/ARM-software/arm-trusted-firmware.git
$ cd arm-trusted-firmware
$ make -C tools/cert_create
$ make -C tools/fiptool

Set up your $PATH to include cert_create and fiptool from above.

Perform the following to sign the image:

$ cd edk2-platforms
$ cert_create -n --ntfw-nvctr 0 --key-alg rsa --nt-fw-key edk2-platforms/Platform/Ampere/JadePkg/TestKeys/Dbb_AmpereTest.priv.pem --nt-fw-cert BUILDS/jade_tianocore_atf/jade_tianocore.fd.crt --nt-fw Build/Jade/RELEASE_GCC5/FV/BL33_JADE_UEFI.fd
$ fiptool create --nt-fw-cert BUILDS/jade_tianocore_atf/jade_tianocore.fd.crt --nt-fw Build/Jade/RELEASE_GCC5/FV/BL33_JADE_UEFI.fd BUILDS/jade_tianocore_atf/jade_tianocore.fip.signed

Integrating Board Setting and Ampere's Arm Trusted Firmware (ATF)

You need to obtain Ampere ATF image and Board Setting file compatible with this vesion of Ampere EDK2 in order to build a final firmware image.

Contact developer@amperecomputing.com for information.

Build Board Setting

Download nvparam.py from this repository to your build machine.

A sample working board setting file is located under Platform/Ampere/{Platform Name}Pkg/.

$ cd edk2-platforms
$ python nvparam.py -f Platform/Ampere/JadePkg/jade_board_setting.txt -o BUILDS/jade_tianocore_atf/jade_board_setting.bin

Build integrated UEFI + Board Setting + ATF image

Generating the final image with the following commands:

$ dd bs=1024 count=2048 if=/dev/zero | tr "\000" "\377" > BUILDS/jade_tianocore_atf/jade_tianocore_atf.img
$ dd bs=1024 conv=notrunc if=<ampere_atf_image_filepath> of=BUILDS/jade_tianocore_atf/jade_tianocore_atf.img
$ dd bs=1024 seek=1984 conv=notrunc if=BUILDS/jade_tianocore_atf/jade_board_setting.bin of=BUILDS/jade_tianocore_atf/jade_tianocore_atf.img
$ dd bs=1024 seek=2048 if=BUILDS/jade_tianocore_atf/jade_tianocore.fip.signed of=BUILDS/jade_tianocore_atf/jade_tianocore_atf.img

Result: BUILDS/jade_tianocore_atf/jade_tianocore_atf.img

Note that the jade_tianocore_atf.img image is flashed at the beginning of the ATF SLIM region according to the SPI-NOR Flash Layout.

Build Tianocore Capsule

For current Ampere ATF

$ build -a AARCH64 -t GCC5 -b RELEASE               \
    -p Platform/Ampere/JadePkg/JadeCapsule.dsc      \
    -D UEFI_ATF_IMAGE=<ampere_atf_image_filepath>   \
    -D SCP_IMAGE=<ampere_scp_slim_image_filepath>
$ cp Build/Jade/RELEASE_GCC5/FV/JADEUEFIATFFIRMWAREUPDATECAPSULEFMPPKCS7.Cap BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap
$ cp Build/Jade/RELEASE_GCC5/FV/JADESCPFIRMWAREUPDATECAPSULEFMPPKCS7.Cap BUILDS/jade_tianocore_atf/jade_scp.cap

Result:
    BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap
    BUILDS/jade_tianocore_atf/jade_scp.cap

For Ampere ATF version 1.05 and earlier

$ dd bs=1024 count=2048 if=/dev/zero | tr "\000" "\377" > BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap.img
$ dd bs=1024 conv=notrunc if=<ampere_atf_image_filepath> of=BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap.img
$ dd bs=1024 seek=1984 conv=notrunc if=BUILDS/jade_tianocore_atf/jade_board_setting.bin of=BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap.img
$ dd bs=1024 seek=2048 if=BUILDS/jade_tianocore_atf/jade_tianocore.fip.signed of=BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap.img
$ openssl dgst -sha256 -sign Platform/Ampere/JadePkg/TestKeys/Dbu_AmpereTest.priv.pem -out BUILDS/jade_tianocore_atf/jade_tianocore_atf.img.sig BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap.img
$ cat BUILDS/jade_tianocore_atf/jade_tianocore_atf.img.sig BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap.img > Build/Jade/RELEASE_GCC5/jade_tianocore_atf.img.signed
$ build -a AARCH64 -t GCC5 -b RELEASE -p Platform/Ampere/JadePkg/JadeCapsule.dsc -D UEFI_ATF_IMAGE=Build/Jade/RELEASE_GCC5/jade_tianocore_atf.img.signed
$ cp Build/Jade/RELEASE_GCC5/FV/JADEFIRMWAREUPDATECAPSULEFMPPKCS7.Cap BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap

Result: BUILDS/jade_tianocore_atf/jade_tianocore_atf.cap
