This example is mainly copied from the great Rust Embedded Cortex-M Quickstart and Jesse Braham's article Embedded Rust: From Zero to Blinky and tweaked for the STM32F446RE of the NUCLEO-F446RE board.

prerequisites: rust, opencd

0. rustup target add thumbv7em-none-eabihf
1. git clone https://github.com/krenzlin/rust-stm32f446-blinky
2. cd rust-stm32f466-blinky
3. cargo build
4. sudo ./flash_device.sh target/thumbv7em-none-eabihf/debug/blinky
5. press the blue user button to turn on the LED

Troubleshooting:
