A Rust-based implementation of Edge-rs for the Raspberry Pi Pico

Getting started

For more details see the following article on getting started for getting your environment set up on Mac/Linux: https://reltech.substack.com/p/getting-started-with-rust-on-a-raspberry

On a Mac, to run minicom: minicom -D /dev/tty.usbmodem14201 -b 115200. Note that you'll most likely need to find the current /dev link assigned to the Pico UART for your particular machine.

Requirements

• The standard Rust tooling (cargo, rustup) which you can install from https://rustup.rs/

• Toolchain support for the cortex-m0+ processors in the rp2040 (thumbv6m-none-eabi)

• flip-link - this allows you to detect stack-overflows on the first core, which is the only supported target for now.

Installation of development dependencies

rustup target install thumbv6m-none-eabi
cargo install flip-link
cargo install cargo-edit
cargo add panic_halt

Running

For a debug build

cargo run

For a release build

cargo run --release

Debugging

To debug you can use either cargo run which will try and launch a gdb session connecting to a local OpenOCD instance at localhost:3333, or you can use VSCode and the cortex-debug extension for VSCode to connect to the same OpenOCD instance.

For more information on getting set up to use OpenOCD with gdb for flashing and debugging your Pico target device, see this getting started guide.
