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
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
