Rust Raspberry Pi Pico / Rust rp2040 Resources

Setup your Rust installation for rp2040 development:

# Add the rp2040 CPU architecture:
rustup self update
rustup update stable
rustup target add thumbv6m-none-eabi

# 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

A broad overview of the rp2040 Rust ecosystem:

• Github rp-rs org
  • rp2040-project-template You will find infos to setup Rust, probe-run and flip-link here.
  • rp-hal - rp2040 Hardware Abstraction Layer You will find other useful setup information here.
    • pico Rust examples
    • rp2040-hal examples
• elf2uf2 converter: cargo install elf2uf2-rs --locked
• Raspberry Pi Pico DapperMime CMSIS-DAP Debug Probe UF2 Image
  • See also: https://github.com/rp-rs/rp2040-project-template/blob/main/debug_probes.md
• heapless - statically allocated data structures
• Cortex-M allocator Use with care, and "it's probably safer to reserve heap space with linker scripts!"
