This is a fork of https://github.com/rust-embedded/cortex-m-quickstart where I get some of their examples running on a NUCLEO-STM32G474RE board.
The goal of this repo is to make a few toy low level embedded stable rust programs that run on hardware.
I'm sticking to low-level hardware abstractions by only using a rust2svd-based
crate (stm32g4 in this case) for hardware abstraction.
I wrote these while following along with the rust-embedded
book
I used the following to build & run these embedded programs on Ubuntu 24.
- Rust 1.78, stable toolchain.
gdb-multiarch&openocdto run the programs on target hardware.- Install udev rules per the embedded book instructions if this is the first time you've used this devkit hardware.
rust-stdcomponents (pre-compiledcorecrate) for ARM Cortex-M4F target. Run:
$ rustup target add thumbv7em-none-eabihfCheck out the book if that doesn't work https://docs.rust-embedded.org/book/intro/install.html
- Build the examples in release and debug profiles with the following commands. The crash example only works in the 'release' profile, so that's why I build both profiles.
cargo build --examples
cargo build --release --examples- Connect the USB ST-LINK port of the NUCLEO-STM32G474RE board to a USB port on your computer.
- From a terminal in the root of this repo, run
openocd. That will pick up the configuration from openocd.cfg for connecting to your devkit. - From a separate terminal, run a gdb command that looks like one of these.
Make sure to pick up gdb configuration with
-x openocd.gdb.
$ gdb-multiarch -x openocd.gdb <path_to_example_binary>
$ gdb-multiarch -x openocd.gdb target/thumbv7em-none-eabihf/debug/examples/mtime
