Cross-compiling Rust project for Cortex-M4 in Windows
Cross-compiling a Rust project for Cortex-M4 on Windows involves a few steps. Here's a general guide to get you started:
Install Rust: If you haven't already, install Rust on your Windows machine by following the official Rust installation guide: https://www.rust-lang.org/tools/install
Install the Rust target: To cross-compile for Cortex-M4, you'll need to install the
thumbv7em-none-eabi
target. Open a command prompt and run the following command:sqlrustup target add thumbv7em-none-eabi
Install the ARM toolchain: Download and install the ARM GCC toolchain for Windows. You can use the GNU Arm Embedded Toolchain available from Arm Developer: https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads
Set environment variables: Add the path to the ARM toolchain binaries to your system's
PATH
environment variable. For example, if you installed the ARM toolchain toC:\Program Files (x86)\GNU Arm Embedded Toolchain\9 2020-q2-update\bin
, add this path to thePATH
environment variable.Configure the Rust project: Create or modify the
Cargo.toml
file in your Rust project to include the necessary target specification. Add the following lines to the[target.'cfg(target_arch = "arm")']
section:toml[target.'cfg(target_arch = "arm")'.dependencies]
cortex-m = "0.7"
cortex-m-rt = "0.6"
panic-halt = "0.2"
Cross-compile the project: Open a command prompt in the project's directory and run the following Cargo command to cross-compile for Cortex-M4:
csscargo build --target thumbv7em-none-eabi
This will build your project using the specified target.
Use the compiled binary: After a successful build, you can use the generated binary in your Cortex-M4 microcontroller environment.
Please note that this is a general guide, and the specific steps may vary depending on your project's requirements and the development environment you are using. Make sure to consult the Rust documentation and the documentation of any relevant libraries or tools for more detailed instructions.
Also, consider using build tools like cargo-binutils
and probe-run
to aid in debugging and flashing the compiled binary onto the microcontroller. These tools provide additional functionality for embedded development with Rust.
