Neotron-BMC-Nucleo

Introduction

This folder is for the Board Management Controller (BMC) when running on an STM32F4 Nucleo board.

This firmware runs on an ST Nucleo-F401RE, for development and debugging purposes. The STM32F401RET6U MCU has:

rustup and Rust
- see https://www.rust-lang.org
The thumbv7em-none-eabi target
- run rustup target add target=thumbv7em-none-eabi
probe-rs
- See https://probe.rs
flip-link
- run cargo install flip-link

Then to build and flash, connect a probe supported by probe-rs (such as a SEGGER J-Link, or an ST-Link) and run:

$ cargo run --release
