Development Setup Guide

This project uses arduino-pico core for debugging RP2040-based Arduino Pico programs with local modifications.

Prerequisites

• Arduino Pico core
• PlatformIO
• CMSIS-DAP compatible debug probe

Setup Process

1. Clone those repositories:

git clone https://github.com/schkovich/arduino-pico.git 
cd arduino-pico
git checkout execute_sync_2433
git submodule update --init
cd ..
git clone [email protected]:schkovich/pico-sdk-tests.git
cd pico-sdk-tests

Project configuration

The arduino-pico core is configured in platformio.ini via platform_package option, pointing to the local folder and “Symbolic Link” feature:

[env:debug]
board = nanorp2040connect
framework = arduino
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board_build.core = earlephilhower
platform_packages =
    framework-arduinopico@symlink://../arduino-pico

Building Core Components

The pico-sdk build process:

1. Compiles core SDK libraries
2. Generates boot stage 2 code for different flash chips
3. Produces required build artifacts for both RP2040 and RP2350

For detailed build steps, see make-libpico.sh in the arduino-pico core.

Development Workflow

• Pico SDK and async_context are pre-built statically linked to the project
• The project is built using PlatformIO
• Debug using CMSIS-DAP probe
