Agilex 5 E-Series GHRD Linux Boot Examples

Introduction

Overview

This page contains instructions on how to build Linux systems from separate components: Hardware Design, U-Boot, Arm Trusted Firmware, Linux kernel and device tree, Linux root filesystem. This is different from the Golden System Reference Design, where all the software is built through Yocto. While the instructions use Yocto for building the root file system, alternatives could be used there, such as the buildroot utility for example.

The following scenarios are covered:

• HPS Enablement Board: boot from SD card, and boot from QSPI
• HPS NAND Board: boot from eMMC flash
• HPS Test Board: boot from SD card

The instructions on this page are based on the GSRD.

Prerequisites

The following are required to be able to fully exercise the guides from this page:

• Altera Agilex 5 FPGA E-Series 065B Premium Development Kit, ordering code DK-A5E065BB32AES1. Refer to board documentation for more information about the development kit.
  • HPS Enablement Expansion Board. Included with the development kit
  • HPS NAND Board. Enables eMMC storage for HPS. Orderable separately
  • HPS Test Board. Supports SD card boot, and external Arm tracing. Orderable separately
  • Mini USB Cable. Included with the development kit
  • Micro USB Cable. Included with the development kit
  • Ethernet Cable. Included with the development kit
  • Micro SD card and USB card writer. Included with the development kit
• Host PC with
  • 64 GB of RAM. Less will be fine for only exercising the binaries, and not rebuilding the GSRD.
  • Linux OS installed. Ubuntu 22.04LTS was used to create this page, other versions and distributions may work too
  • Serial terminal (for example GtkTerm or Minicom on Linux and TeraTerm or PuTTY on Windows)
  • Intel Quartus Prime Pro Edition version 24.1. Used to recompile the hardware design. If only writing binaris is required, then the smaller Intel Quartus Prime Pro Edition Programmer version 24.1 is sufficient.
  • TFTP server. This used to download the eMMC binaries to board to be flashed by U-Boot
• Local Ethernet network, with DHCP server
• Internet connection. For downloading the files.

Development Kit

Refer to Development Kit for details about the board, including how to install the HPS Boards, and how to set MSEL dispswitches.

Release Notes

Refer to Release Notes for release readiness information and known issues.

HPS Enablement Board

This section demonstrates how to build a Linux system from separate components, targetting the HPS Enablement Board. Both booting from SD card and booting from QSPI are covered.

Boot from SD Card

Setup Environment

1. Create the top folder to store all the build artifacts:

sudo rm -rf artifacts.enablement
mkdir artifacts.enablement
cd artifacts.enablement
export TOP_FOLDER=`pwd`

2. Download and setup the build toolchain. It will be used only by the GHRD makefile to build the debug HPS FSBL, to build the _hps_debug.sof file:

cd $TOP_FOLDER
wget https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/binrel\
/gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu.tar.xz
tar xf gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu.tar.xz
rm -f gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu.tar.xz
export PATH=`pwd`/gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu/bin:$PATH
export ARCH=arm64
export CROSS_COMPILE=aarch64-none-linux-gnu-

3. Set up the Quartus tools in the PATH, so they are accessible without full path

export QUARTUS_ROOTDIR=~/intelFPGA_pro/24.1/quartus/
export PATH=$QUARTUS_ROOTDIR/bin:$QUARTUS_ROOTDIR/linux64:$QUARTUS_ROOTDIR/../qsys/bin:$PATH

Write SD Card

Write the SD card image sd_card/sdimage.img to the micro SD card using the included USB writer, and dd utility on Linux, or Win32DiskImager on Windows, available at https://win32diskimager.org/.

Write QSPI Flash

1. Power down board

2. Set MSEL dipswitch SW27 to JTAG: OFF-OFF-OFF-OFF

3. Power up the board

4. Write JIC image to QSPI:

cd $TOP_FOLDER
quartus_pgm -c 1 -m jtag -o "pvi;ghrd.hps.jic"

Boot Linux

1. Power down board

2. Set MSEL dipswitch SW27 to QSPI: OFF-ON-ON-OFF

3. Power up the board

4. Wait for Linux to boot, use root as user name, and no password wil be requested.

Boot from QSPI

This section presents how to build the binaries and boot from QSPI with the HPS Enablement Board. While the example is based on the GSRD, it contains the following differences:

• U-Boot tries to boot only from QSPI flash, does not try SD card
• U-Boot does not use a script to boot, instead it used the BOOTCMD environment variable directly
• kernel.itb file contains only one set of core.rbf, kernel and device tree files, targeted for this scenario

1. Prepare the top folder

rm -rf $TOP_FOLDER/qspi-boot
mkdir $TOP_FOLDER/qspi-boot

2. Build U-Boot:

cd $TOP_FOLDER/qspi-boot

HPS NAND Board

This section demonstrates how to build a Linux system from separate components, targetting the HPS NAND Board. Boot source is eMMC Flash.

Boot from eMMC

Setup Environment

1. Create the top folder to store all the build artifacts:

sudo rm -rf artifacts.emmc
mkdir artifacts.emmc
cd artifacts.emmc
export TOP_FOLDER=`pwd`

2. Download and setup the build toolchain. It will be used only by the GHRD makefile to build the debug HPS FSBL, to build the _hps_debug.sof file:

cd $TOP_FOLDER
wget https://developer.arm.com/-/media/Files/downloads/gnu/11.2-2022.02/binrel\

1. Write the helper JIC to QSPI:

• Power down board
• Set MSEL dipswitch SW27 to JTAG: OFF-OFF-OFF-OFF
• Power up the board
• Write JIC image to QSPI:

  cd $TOP_FOLDER
  quartus_pgm -c 1 -m jtag -o "pvi;helper-jic/flash.hps.jic"
  

2. Boot to U-Boot prompt with the helper JIC:

• Power down board
• Set MSEL dipswitch SW27 to QSPI: OFF-ON-ON-OFF
• Power up the board
• Wait for U-Boot to boot, press any key to get to U-Boot console

3. Use ifconfig on your host machine to determine the IP of your TFTP server

4. Copy the eMMC image $TOP_FOLDER/sd_card/sdcard.img to your TFTP server folder

5. Use the following U-Boot commands to download and write the eMMC image:

setenv autoload no
dhcp
setenv serverip <your_tftp_server_ip>
tftp ${loadaddr} sdcard.img
setexpr blkcnt ${filesize} / 0x200
mmc write ${loadaddr} 0 ${blkcnt}

Write QSPI Flash

1. Power down board

Build QSPI Image

cd $TOP_FOLDER

Build HPS RBF

This is an optional step, in which you can build an HPS RBF file, which can be used to configure the HPS through JTAG instead of QSPI though the JIC file.

cd $TOP_FOLDER
quartus_pfg -c agilex5_soc_devkit_ghrd/output_files/ghrd_a5ed065bb32ae6sr0.sof ghrd.rbf \
-o hps_path=$TOP_FOLDER/u-boot-socfpga/spl/u-boot-spl-dtb.hex \
-o hps=1

The following file is created:

Write SD Card

Write the SD card image sd_card/sdimage.img to the micro SD card using the included USB writer, and dd utility on Linux, or Win32DiskImager on Windows, available at https://win32diskimager.org/.

Write QSPI Flash

1. Power down board

2. Set MSEL dipswitch SW27 to JTAG: OFF-OFF-OFF-OFF

3. Power up the board

4. Write JIC image to QSPI:

cd $TOP_FOLDER
quartus_pgm -c 1 -m jtag -o "pvi;ghrd.hps.jic"

Boot Linux

1. Power down board

2. Set MSEL dipswitch SW27 to QSPI: OFF-ON-ON-OFF

3. Power up the board

4. Wait for Linux to boot, use root as user name, and no password wil be requested.
