The most important changes in SoC EDS 20.1 are:

Arm DS-5 is not automatically installed with SoC EDS.
Users need to download and install Arm DS separately. Arm DS is the successor of Arm DS-5 and offers similar functionality.
Mentor bare-metal toolchain for Cortex-A9 is not installed with SoC EDS
Users need to download and install Linaro bare-metal toolchain for Cortex-A9 separately. It offers similar functionality with Mentor bare-metal toolchain.
Arria 10 HWLIBs bare-metal timer example was updated to
- Use either the Linaro or Arm compiler
- Use either OCRAM or DDR memory
- Use either semihosting or UART for console
- Copy all relevant HWLIBs files in the project. This allows easy customization of HWLIBs source code without changing the master copy inside SoC EDS.

The SoC EDS User Guide will be updated at a later date.

Installation

The installation process consists of the following steps:

Download and install SoC EDS
Download and install Arm DS
Download and install Linaro bare-metal toolchain

In addition to the above, the following need to be installed on Windows machines:

Cygwin - offers a Linux-like enviornment on Windows, and is required by the Embedded Command Shell
MinGW - used as a platform to build the Newlib library used by the Linaro bare-metal toolchain.

SoC EDS Licensing

The only SoC EDS component which requires a license is the Arm DS Intel SoC FPGA Edition. Two license options are available:

Arm DS Intel SoC FPGA Edition License
30-day Evaluation of Arm DS Intel SoC FPGA Edition License

Note: The 30-day Evaluation of Arm DS Intel SoC FPGA Edition License applies only to latest version of Arm DS, downloadable from https://developer.arm.com/tools-and-software/embedded/arm-development-studio/downloads

Refer to Arm DS Intel® SoC FPGA Edition Toolkit for details about DS features, and editions, including licensing.

Getting the License

Follow the steps below to get the License:

For Arm DS Intel SoC FPGA Edition License - If you have purchased a SoC development kit or a stand-alone license for DS Intel SoC FPGA Edition AE, then you have already received an Arm license serial number. This is a 15-digit alphanumeric string with two dashes in between. Use this serial number to activate your license in DS Intel SoC FPGA Edition, as shown in the "Activating the License" section.

For 30-Day Evaluation of DS-5 Intel SoC FPGA Edition License - If you want to evaluate the DS Intel SoC FPGA Edition, you can get a 30-Day Evaluation activation code by going to Arm DS Intel® SoC FPGA Edition Toolkit then clicking on Activate license code for Arm DS.

Activating the License

This section presents how to activate and apply the license.

1. Go to ARM Licensing Portal to generate a license file based on the license code you got with your Development Kit.

2. Start DS IDE

3. First time it is run it will ask you to add a product license. Select Add product license and click Next.

5. Select License File and browse to the place where you stored your generated license. Click Next.

6. The Arm Development Studio Intel FPGA Edition license will be selected. Click Next to activate it.

7. License will be activated. Click Finish to complete the process.

Arria 10 Bare Metal Example Using SoC EDS Pro Edition

This section contains instructions on running the Arria 10 Timer bare-metal example provided with SoC EDS. The example targets the Arria 10 SoC Development Kit.

The following are covered:

Configuring the FPGA: the FPGA needs to be configured first, to be able to bring up HPS DDR
Running U-Boot SPL: the SPL needs to be ran to initialize hardware and bring up HPS DDR
Exercise Application: importing, building and running the sample application
Customize sample application: change compiler, memory and semihosting options

The example was created on Linux, but it will work similarily on Windows. The only step that can only be performed on Linux is compiling U-Boot.

Configure FPGA

1. Start an Embedded Command Shell

~/intelFPGA_pro/20.1/embedded/embedded_command_shell.sh

2. Configure FPGA with the SOF file included with SoC EDS:

quartus_pgm -c 1 -m jtag -o "p;$SOCEDS_DEST_ROOT/examples/hardware/a10_soc_devkit_ghrd/output_files/ghrd_10as066n2.sof"

Build U-Boot

Note: U-Boot can only be built on Linux.

1. Start an Embedded Command Shell

~/intelFPGA_pro/20.1/embedded/embedded_command_shell.sh

2. Build U-Boot

# Generate U-Boot device tree
cd $SOCEDS_DEST_ROOT/examples/hardware/a10_soc_devkit_ghrd/
rm -rf software/bootloader
mkdir -p software/bootloader
cd software/bootloader

# Get the U-Boot sourece code
git clone https://github.com/altera-opensource/u-boot-socfpga
cd u-boot-socfpga
git checkout -b test -t origin/socfpga_v2020.04

# Generate DTS include file based on the handoff file
./arch/arm/mach-socfpga/qts-filter-a10.sh \

# Build U-Boot
export CROSS_COMPILE=arm-eabi-
make socfpga_arria10_defconfig
make -j 24

The following files are created in $SOCEDS_DEST_ROOT/examples/hardware/a10_soc_devkit_ghrd/software/bootloader/u-boot-socfpga:

spl/u-boot-spl - SPL executable
spl/u-boot-spl-dtb.bin - SPL device tree
u-boot - U-Boot executable
u-boot-dtb.bin - U-Boot device tree
u-boot-with-spl.sfp - flash image file with 4 x SPL + U-Boot image

3. Create SPL debug script
