Development Requirements

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

• Rust nightly

• 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.

• probe-run

• A CMSIS-DAP probe. (J-Link and other probes will not work with probe-run)

  You can use a second Pico as a CMSIS-DAP debug probe. Details on other supported debug probes can be found in debug_probes.md

Installation of development dependencies

rustup install nightly
rustup +nightly target add thumbv6m-none-eabi
cargo +nightly install flip-link
cargo +nightly install probe-run --locked

Running

For a debug build

cargo run

For a release build

cargo run --release

If you do not specify a DEFMT_LOG level, it will be set to debug. That means println!(""), info!("") and debug!("") statements will be printed. If you wish to override this, you can change it in .cargo/config.toml

[env]
DEFMT_LOG = "off"

You can also set this inline (on Linux/MacOS)

DEFMT_LOG=trace cargo run

or set the environment variable so that it applies to every cargo run call that follows:

Linux/MacOS/unix

export DEFMT_LOG=trace

Setting the DEFMT_LOG level for the current session
for bash

export DEFMT_LOG=trace

Windows

Windows users can only override DEFMT_LOG through config.toml or by setting the environment variable as a separate step before calling cargo run

• cmd

set DEFMT_LOG=trace

• powershell

$Env:DEFMT_LOG = trace

cargo run

Roadmap

NOTE: This software is under active development. As such, it is likely to remain volatile until a 1.0.0 release.
