Linux x86_64

sh curl -L https://github.com/esp-rs/espup/releases/latest/download/espup-x86_64-unknown-linux-gnu -o espup chmod a+x espup

macOS aarch64

sh curl -L https://github.com/esp-rs/espup/releases/latest/download/espup-aarch64-apple-darwin -o espup chmod a+x espup

macOS x86_64

Quickstart

See Usage section for more details.

Install

• no_std sh espup install # Unix . ./export-esp.sh # Windows .\export-esp.ps1
• std: Installing esp-idf via espup is not mandatory, as esp-idf-sys already takes care of it, but has some benefits. sh espup install --espidf-version <ESPIDF_VERSION> # Unix . ./export-esp.sh # Windows .\export-esp.ps1

Warning

The generated export file, by default export-esp, needs to be sourced in every terminal before building an application.

Uninstall

sh espup uninstall

Update

sh espup update

``` Usage: espup

Commands: install Installs esp-rs environment uninstall Uninstalls esp-rs environment update Updates Xtensa Rust toolchain help Print this message or the help of the given subcommand(s)

Options: -h, --help Print help information -V, --version Print version information ```

Install Subcommand

Note

Installation paths can be modified by setting the environment variables CARGO_HOME and RUSTUP_HOME before running the install command. Xtensa Rust toolchain will be installed under <rustup_home>/toolchains/esp.

``` Usage: espup install [OPTIONS]

Options: -d, --default-host Target triple of the host

-e, --espidf-version ESP-IDF version to install. If empty, no esp-idf is installed. Version format:

      - `commit:<hash>`: Uses the commit `<hash>` of the `esp-idf` repository.

      - `tag:<tag>`: Uses the tag `<tag>` of the `esp-idf` repository.

      - `branch:<branch>`: Uses the branch `<branch>` of the `esp-idf` repository.

      - `v<major>.<minor>` or `<major>.<minor>`: Uses the tag `v<major>.<minor>` of the `esp-idf` repository.

      - `<branch>`: Uses the branch `<branch>` of the `esp-idf` repository.

      When using this option, `ldproxy` crate will also be installed.

-v, --toolchain-version Xtensa Rust toolchain version

      [default: 1.64.0.0]

-h, --help Print help information (use -h for a summary) ```

Known Issues or Limitations

• If installing esp-idf in Windows, only all targets is allowed.
• In Windows, when installing esp-idf fails with: ERROR: Could not find a version that satisfies the requirement windows-curses; sys_platform == "win32" (from esp-windows-curses) (from versions: none) ERROR: No matching distribution found for windows-curses; sys_platform == "win32" Traceback (most recent call last): File "<home_dir>/.espressif\esp-idf-ae062fbba3ded0aa\release-v4.4\tools\idf_tools.py", line 1973, in <module> main(sys.argv[1:]) File "<home_dir>/.espressif\esp-idf-ae062fbba3ded0aa\release-v4.4\tools\idf_tools.py", line 1969, in main action_func(args) File "<home_dir>/.espressif\esp-idf-ae062fbba3ded0aa\release-v4.4\tools\idf_tools.py", line 1619, in action_install_python_env subprocess.check_call(run_args, stdout=sys.stdout, stderr=sys.stderr, env=env_copy) File "C:\Python311\Lib\subprocess.py", line 413, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['<home_dir>/.espressif\\python_env\\idf4.4_py3.11_env\\Scripts\\python.exe', '-m', 'pip', 'install', '--no-warn-script-location', '-r', <home_dir>/.espressif\\esp-idf-ae062fbba3ded0aa\\release-v4.4\\requirements.txt', '--extra-index-url', 'https://dl.espressif.com/pypi']' returned non-zero exit status 1. Error: Could not install esp-idf _Solution_: Use a python version between 3.6 and 3.10 as 3.11 Python wheels are not yet released for Windows.
