RISC-V on MAX10 User Guide

3.3 RISC-V GCC

This guide installs the toolchain under /opt/riscv, this path is configurable. For other Linux distributions

the toolchain can be installed similarly. For more information, please visit the official

Toolchain

repository.

Note: To use the RISC-V GCC toolchain on Windows the

The guide for Ubuntu then applies.

The first step is to download the prerequisites. Open a terminal window and enter the following command:

sudo apt-get install autoconf automake autotools-dev curl python3 libmpc-dev

libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool

patchutils bc zlib1g-dev libexpat-dev

Navigate to a temporary directory and clone the toolchain from github:

git clone https://github.com/riscv/riscv-gnu-toolchain

riscv-gnu-toolchain

Configure the build for the available architectures and run make to start the build:

Note: This step may take a while.

./configure --prefix=/opt/riscv

"rv32im-ilp32-rv32ima-;rv32imc-ilp32-rv32imac-;rv32imafc-ilp32f--"

sudo make

Add the build tools to the path by opening ~/.bashrc (or equivalent) and add the line:

export

PATH="$PATH:/opt/riscv/bin"

Finally reload the terminal with the following command:

source

~/.bashrc

Now the RISC-V tools are available on the terminal via riscv64-unknown-elf-(*)

3.4 Intel Quartus Prime

To synthesize the hardware design

free of charge, please make sure that the MAX10 Device support is included.

To make the RISC-V cores available for the Intel Platform Designer open Quartus and under the menu Tools

select Options. There select IP Settings > Ip Catalog Search Locations and add the the following

path to the Global IP search directory, substituting the path to the repository previously cloned:

<path to repository>/Cores/**/*

The MAX10 SoM is programmed via JTAG either through the intregrated PIC microcontroller using a

Serial Vector Format (.svf) file or through a Quartus Prime compatible USB-Blaster connected to the JTAG

Header on the Spider Baseboard.

Chapter 3. Requirements

Windows Subsystem for Linux

--with-multilib-generator="rv32i-ilp32--;"\

Intel Quartus Prime

is required. The lite edition is available from Intel

RISC-V GNU Compiler

is recommended.
