TizenRT

TizenRT is a lightweight RTOS (Real-Time Operating System) designed to support low-end IoT devices. It aims to extend the Tizen platform device coverage to devices like home appliances without display and wearable bands with a small LCD. These devices are typically equipped with Cortex-M/R processors with MPU, less than 2 MB RAM, and less than 16 MB Flash.

Features

• RTOS-based Platform: Specifically designed for low-end IoT devices.
• IPv6 Support: Includes support for Neighbor Discovery (ND6), Multicast Listener Discovery (MLD), and ICMPv6 protocols.
• Docker Build Environment: Provides an easy way to build using Docker, eliminating the need for manual library and toolchain installations.
• Media Framework: Offers player/recorder functionalities for voice/audio streaming.
• Task Manager Framework: Enables control and messaging between applications.
• Network Monitoring Tool: Monitors real-time information regarding network sockets, network interface, and WiFi Manager.
• gRPC for Client Roles: Supports various RPC types and both insecure and secure modes of RPC execution.
• HTTP/2 Support: Ported nghttp2 version 1.32.0 from Github.

Components

• Kernel and System: Provides features like stack trace in text, new pthread_tryjoin_np API, and Docker build environment.
• Network and Connectivity: Offers IPv6 support, network monitoring tools, gRPC for client roles, and HTTP/2.
• Framework: Includes a media framework, voice control manager, task manager framework, and Wi-Fi manager framework.
• External: Incorporates libc++, protocol buffer, cURL, and a stress test tool.
