RaspberryPi PICO用のRust環境構築

Posted at

RaspberryPi PICO用のRust開発環境を構築していきます。

Rust Toolchainのインストール


% mkdir rust
% cd rust
% curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
info: downloading installer

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:


This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory located at:


This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:


This path will then be added to your PATH environment variable by
modifying the profile files located at:


You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Current installation options:

   default host triple: x86_64-apple-darwin
     default toolchain: stable (default)
               profile: default
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

info: profile set to 'default'
info: default host triple is x86_64-apple-darwin
info: syncing channel updates for 'stable-x86_64-apple-darwin'
info: latest update on 2021-12-02, rust version 1.57.0 (f1edd0429 2021-11-29)

  stable-x86_64-apple-darwin installed - rustc 1.57.0 (f1edd0429 2021-11-29)

Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).

To configure your current shell, run:
source $HOME/.cargo/env
% source $HOME/.cargo/env



% rustup --version
rustup 1.24.3 (ce5817a94 2021-05-31)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.57.0 (f1edd0429 2021-11-29)`
% rustc --version 
rustc 1.57.0 (f1edd0429 2021-11-29)
% cargo --version 
cargo 1.57.0 (b2e52d7ca 2021-10-21)


RP2040のアーキテクチャはデュアルARM Cortex-M0+ @ 133 MHzなので、Cortex-M0+がターゲットとなります。

ビルドされたファイルは、elf形式なのでuf2形式にしてRaspberryPi PICOにコピーする必要があります。


% vi .cargo/config.toml
# runner = "probe-run --chip RP2040"
runner = "elf2uf2-rs -d"

cargo runコマンドでファイルをRaspberryPi PICOに転送します。
