# 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` is configured as the default runner, so you can start your program as easy as
```sh
cargo run --release
```
If you aren't using a debugger (or want to use cargo-embed/probe-rs-debugger), check out [alternative runners](#alternative-runners) for other options

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 was added with version 0.3.1.
- 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 by installing either of the following firmware on it:
https://github.com/majbthrd/DapperMime/releases/download/20210225/raspberry_pi_pico-DapperMime.uf2
https://raw.githubusercontent.com/9names/binary-bits/main/rust-dap-pico-ramexec-setclock.uf2
More details on supported debug probes can be found in [debug_probes.md](debug_probes.md)
Installation of development dependencies
```sh
rustup target install thumbv6m-none-eabi
cargo install flip-link
# This is our suggested default 'runner'
cargo install probe-run
# If you want to use elf2uf2-rs instead of probe-run, instead do...
cargo install elf2uf2-rs --locked
```
Running
For a debug build
```sh
cargo run
```
For a release build
```sh
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`
```toml
[env]
DEFMT_LOG = "off"
```
You can also set this inline (on Linux/MacOS)
```sh
DEFMT_LOG=trace cargo run
```
or set the _environment variable_ so that it applies to every `cargo run` call that follows:
#### Linux/MacOS/unix
```sh
export DEFMT_LOG=trace
```
Setting the DEFMT_LOG level for the current session
for bash
```sh
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
```cmd
set DEFMT_LOG=trace
```
- powershell
```ps1
$Env:DEFMT_LOG = trace
```
```cmd
cargo run
```
Alternative runners
If you don't have a debug probe or if you want to do interactive debugging you can set up an alternative runner for cargo.
Some of the options for your `runner` are listed below:
* **cargo embed**
*Step 1* - Install [`cargo embed`](https://github.com/probe-rs/cargo-embed):
```console
$ cargo install cargo-embed
```
*Step 2* - Make sure your .cargo/config contains the following
```toml
[target.thumbv6m-none-eabi]
runner = "cargo embed"
```
*Step 3* - Update settings in [Embed.toml](./Embed.toml)
- The defaults are to flash, reset, and start a defmt logging session
You can find all the settings and their meanings [in the cargo-embed repo](https://github.com/probe-rs/cargo-embed/blob/master/src/config/default.toml)
*Step 4* - Use `cargo run`, which will compile the code and start the
specified 'runner'. As the 'runner' is cargo embed, it will flash the device
and start running immediately
```console
$ cargo run --release
```
* **probe-rs-debugger**
*Step 1* - Download [`probe-rs-debugger VSCode plugin 0.4.0`](https://github.com/probe-rs/vscode/releases/download/v0.4.0/probe-rs-debugger-0.4.0.vsix)
*Step 2* - Install `probe-rs-debugger VSCode plugin`
```console
$ code --install-extension probe-rs-debugger-0.4.0.vsix
```
*Step 3* - Install `probe-rs-debugger`
```console
$ cargo install probe-rs-debugger
```
*Step 4* - Open this project in VSCode
*Step 5* - Launch a debug session by choosing `Run`>`Start Debugging` (or press F5)
* **Loading a UF2 over USB**
*Step 1* - Install [`elf2uf2-rs`](https://github.com/JoNil/elf2uf2-rs):
```console
$ cargo install elf2uf2-rs --locked
```
*Step 2* - Make sure your .cargo/config contains the following
```toml
[target.thumbv6m-none-eabi]
runner = "elf2uf2-rs -d"
```
The `thumbv6m-none-eabi` target may be replaced by the all-Arm wildcard
`'cfg(all(target_arch = "arm", target_os = "none"))'`.
*Step 3* - Boot your RP2040 into "USB Bootloader mode", typically by rebooting
whilst holding some kind of "Boot Select" button. On Linux, you will also need
to 'mount' the device, like you would a USB Thumb Drive.
*Step 4* - Use `cargo run`, which will compile the code and start the
specified 'runner'. As the 'runner' is the elf2uf2-rs tool, it will build a UF2
file and copy it to your RP2040.
```console
$ cargo run --release
```
* **Loading with picotool**
As ELF files produced by compiling Rust code are completely compatible with ELF
files produced by compiling C or C++ code, you can also use the Raspberry Pi
tool [picotool](https://github.com/raspberrypi/picotool). The only thing to be
aware of is that picotool expects your ELF files to have a `.elf` extension, and
by default Rust does not give the ELF files any extension. You can fix this by
simply renaming the file.
This means you can't easily use it as a cargo runner - yet.
Also of note is that the special
[pico-sdk](https://github.com/raspberrypi/pico-sdk) macros which hide
information in the ELF file in a way that `picotool info` can read it out, are
not supported in Rust. An alternative is TBC.
## Roadmap
NOTE These packages are under active development. As such, it is likely to
remain volatile until a 1.0.0 release.
See the [open issues](https://github.com/rp-rs/rp2040-project-template/issues) for a list of
proposed features (and known issues).
