OBSOLETE

This is no longer the recommended way to get a Rust toolchain for RISCV. Instead, you can clone the riscv-rust/rust fork of Rust and build it as normal:

./x.py build

You can use

make toolchain

to build binutils and openocd for RISCV.

Rust Toolchain for RISCV

Supported boards

• hifive (RV32IMAC)

Getting started

1. Get the source

git clone --recursive https://github.com/riscv-rust/riscv-rust-toolchain
cd riscv-rust-toolchain

2. Install build dependencies See manifest.scm for a list of the required build dependencies.

3. Build the toolchain A list of all set environment variables is in build-env.sh, adapt to your distro if necessary.

# Builds llvm openocd binutils rust and xargo
make toolchain

4. Clone quickstart template

git clone https://github.com/riscv-rust/riscv-rust-quickstart
cd riscv-rust-quickstart

5. Follow instructions in riscv-rust-quickstart's README.md

RISCV crates

• riscv crate provides routines for riscv specific asm instructions and reading/writing csr's.

• riscv-rt crate provides startup code, linker script and interrupt handling code.

• e310x crate is a svd2rust generated api to Freedom E310 MCU peripherals.

• hifive crate is a board support crate for the hifive board.
