Overview

Project template for rp2040-hal

This template is intended as a starting point for developing your own firmware based on the rp2040-hal.

It includes all of the knurling-rs tooling as showcased in https://github.com/knurling-rs/app-template (defmt, defmt-rtt, panic-probe, flip-link) to make development as easy as possible.

probe-run-rp is configured as the default runner, so you can start your program as easy as

cargo run --release

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.

  • probe-run. Upstream support for RP2040 is not finished yet, so this template uses probe-run-rp for now. probe-run-rp is a version of probe-run using a probe-rs fork with support for the RP2040 chip. Note that this installs the binary with name probe-run-rp, so you can still have the original probe-run installed in parallel.

    This is important because probe-run-rp ONLY works with the RP2040 chip.

  • A CMSIS-DAP probe. (JLink probes sort of work but are very unstable. Other probes won't work at all)

    You can use a second Pico as a CMSIS-DAP debug probe by installing the following firmware on it: https://github.com/majbthrd/DapperMime/releases/download/20210225/raspberry_pi_pico-DapperMime.uf2

    More details on supported debug probes can be found in debug_probes.md

    typo: fix misspelled elf2uf2-rs

    In README.md, elf2uf2-rs has been misspelled as elf2usb2-rs in installation commands. In .cargo/config.toml, a quotation mark need to be added. For users who use VS Code with Rust Analyzer, setting target architecture could help them to avoid warning like no tests module.

    Failed to read register DRW at address 0x0000000c

    Hello, Please redirect me if this is the wrong resource to post this kind of issue, but I've found no place better than this issue tracker as I use this template to run Rust on my RPi Pico;

    With the guide in the Readme I connected two Picos, making one of them a probe and run debug build like this:

    DEFMT_LOG=trace cargo run

    It seems working, but it lasts only for a few seconds:

    If I re-run this command, it won't even start (and blinky stops work as well):

    However, when I reconnect the target Pico, it flashes and runs for a sec as before, then the same issue starts again.

  • Set DEFMT_LOG to

    Set DEFMT_LOG to "debug" from .cargo/config.toml

    This is for discussion: Since changing to defmt 0.3.0, most of the time I run a new firmware for the first time, I forget to set DEFMT_LOG. And during development, I usually want more logging than the default. So I wonder if it would be good to set this by default on rp2040-project-template.

    Pro:

    • it's usually a better choice when starting a new project
    • easier for new users (avoids questions like "why doesn't info!(...) work?")

    Con:

    • quite invisible, so new users don't learn about DEFMT_LOG

    Fix BSP name: pico to rp-pico, rp_pico

    Since BSP rp-pico has been renamed from pico (https://github.com/rp-rs/rp-hal/pull/245/commits/8f0a2788eb05813f61c38eb502fc88b5bba749b7), we cannot build this template. This commit will fix it.

  • Use pico bsp

    Use pico bsp

    The template is currently based around the HAL directly. BSP's help remove a bunch of boilerplate that never changes (configuring boot2, providing xtal freq, etc), and are generally more newbie-friendly - we should encourage ourselves and others to use them instead! This PR sets the BSP to Pico, with a few commented lines on how to switch this to the pro_micro_rp2040.

    Do not merge this until the boot2 changes are merged into the BSPs (https://github.com/rp-rs/rp-hal/pull/153) Resolves #9.

  = help: some `extern` functions couldn't be found; some native libraries may need to be installed or have their path specified
  = note: use the `-l` flag to specify native libraries to link
  = note: use the `cargo:rustc-link-lib` directive to specify the native libraries to link with Cargo (see https://doc.rust-lang.org/cargo/reference/build-scripts.html#cargorustc-link-libkindname)

    I expected it to at least generate the "binary" and fail at the install step, since I have not studied the exact procedure for getting firmware onto the RP2040 (The arduino IDE can send a sketch over the USB cable, but I have read other articles talking about holding the boot button while copying a file over USB)

    Did I fail to copy something, or has there been some API drift that broke the sample app?

    Add cargo embed config + docs

    We previously only had probe-run as a debug configuration. Now that cargo embed supports defmt, gdb and a bunch of other stuff we should document that as well. Need to use a git version, since the latest release does not support rp2040

  • repo / crate name

    repo / crate name

    This was originally intended to be used like https://github.com/knurling-rs/app-template, so an end-user would create a new project from this repo using cargo-generate and it would rename the crate, add authors, etc That's not how it currently works - and I'm not sure we even want that. Beginners are way more likely to clone/download this repo and then wonder why nothing works if they needed to run cargo-generate. And not everyone is comfortable around the terminal, we should want to support IDE-only users..

    So maybe this should be named rp2040-quickstart, or something more accurate and obvious.
