UniRTOS SDK

English | 简体中文

UniRTOS SDK is a unified embedded development kit for multiple Quectel cellular module platforms. It provides consistent APIs and component architecture, supports cross-platform development and efficient porting, and integrates rich middleware, drivers, protocol stacks, and application examples to accelerate the development and deployment of intelligent embedded devices.

Key Features

• Multi-platform support (for example, eigen_718)
• Based on the FreeRTOS kernel and adaptable to multiple hardware architectures
• Modular design with flexible feature trimming
• Rich drivers and middleware (networking, storage, audio, camera, FOTA, NVM, and more)
• Kconfig-based configuration with menuconfig UI support
• CMake build system with Ninja/Make backends
• Standard application examples and secondary development interfaces

Quick Start

1. Install Toolchain and CLI

• Development Preparation
• Install Cross-Compilation Toolchain
• Install Python3
• Install Git
• Install unirtos-cli: pip install unirtos-cli

Verify the environment:

python --version # Python3
git --version
unirtos --version # 1.0.5 or later
unirtos-cli version # 1.0.15 or later

2. Create a Project with unirtos-cli

unirtos-cli new unirtos-app
cd unirtos-app

Edit env_config.json and configure at least:

• sdk.version
• build.module

Optional fields:

• build.version
• libraries.list

3. Pull SDK and Libraries

unirtos-cli env-setup

4. Configure, Build, and Clean

unirtos-cli menuconfig
unirtos-cli build
unirtos-cli clean

Build Outputs

• Build outputs are generated in qos_build/release/<version>/ under the project directory.
• <version> is resolved in this order: use the name passed by unirtos-cli build -v/--version first; if not provided, use build.version from env_config.json; otherwise, use the app root folder name (the folder containing env_config.json).
