# Rust Raspberry Pi Pico / Rust rp2040 Resources
# WeirdConstructor's Rust Code Snippets/Projects for the rp2040 (Raspberry Pi Pico)
Setup your Rust installation for rp2040 development:
A link to the resource / link collection I made: ![rp2040 Rust resources](resources.md)
```
# Add the rp2040 CPU architecture:
rustup self update
rustup update stable
rustup target add thumbv6m-none-eabi
An overview of this repository:
# Useful to creating UF2 images for the RP2040 USB Bootloader
cargo install elf2uf2-rs --locked
# Useful for flashing over the SWD pins using a supported JTAG probe
cargo install --git https://github.com/rp-rs/probe-run.git --branch rp2040-support
# flip-link detect stack-overflows on the first core
# (which is the only supported target for now.)
cargo install flip-link
```

- [Github rp-rs org](https://github.com/rp-rs/)
- [rp2040-project-template](https://github.com/rp-rs/rp2040-project-template)
You will find infos to setup Rust, probe-run and flip-link here.

You will find other useful setup information here.

Use with care, and "it's probably safer to reserve heap space with linker scripts!"
