rp2040tools

This repo contains all the tools used by Arduino to upload compiled code to the boards that use the rp2040 processor.

Tools

• picotool: a tool for interacting with a RP2040 device in BOOTSEL mode, or with a RP2040 binary
• elf2uf2: a tool to convert binary format
• rp2040load is a go tool which orchestrates the other two
• pioasm

CI

The CI is responsible for building and uploading the tools The release workflow is divided in:

• a job which uses a docker container (called crossbuild) with all the toolchains inside required to cross-compile the tools from raspberry pi. The binaries produced are as static and self-contained as possible.
• a job that cross-compiles the go tool called rp2040load.
• one last job used to move in the correct folders the binaries and to tar.bz2 them and upload them in the github release page and on s3 download server.
