This repository is the official ROS 2 build tooling package for micro-ROS. At runtime it exposes bash entry points (`create_firmware_ws.sh`, `configure_firmware.sh`, `build_firmware.sh`, `flash_firmware.sh`, `create_agent_ws.sh`, `build_agent.sh`) and a `component` CLI. These scripts scaffold a workspace containing a development ROS 2 workspace (`dev_ws`), a microcontroller client workspace (`mcu_ws`), and platform-specific code, then delegate to per-RTOS/per-board scripts under `config/`. It is an orchestration and configuration layer: actual micro-ROS client/agent code, RTOS kernels, and toolchains are fetched from GitHub via vcstool `.repos` files. The package supports FreeRTOS on several STM32 boards, ESP32, Crazyflie, Zephyr on multiple boards, native Linux host, Android NDK, Raspberry Pi cross-compilation, and generation of a standalone static library. CI builds a large matrix nightly, so platform support is verified at the level of 'a binary exists after build'. The code is pragmatic shell with significant duplication across platform folders; each platform directory follows a conventional `create/configure/build/flash` contract that the top-level scripts discover dynamically. Because platform toolchains are pinned by each `create.sh` (Zephyr 2.6.0, ESP-IDF 4.1, ARM GCC 8-2019q3), some entries are stale, and the README itself disclaims production readiness. Still, the repository is actively maintained, tracks current ROS 2 distributions, and its workflow is battle-tested for micro-ROS bring-up.
