The Tactile Intelligence RK3506 core board/Star Flash development board has achieved a significant breakthrough, being the first to complete the adaptation of the open-source Harmony OpenHarmony 5.1 L1 (small system), while also supporting Hisilicon Star Flash wireless communication (Star Flash + WiFi + Bluetooth).
This technological achievement marks Tactile Intelligence’s realization of 100% domestically produced software and hardware for the RK3506 core board, launching the “Star Flash + Open Source Harmony OpenHarmony” hardcore solution.
Tactile Intelligence also takes this opportunity to introduce the types of the open-source Harmony OpenHarmony system and its application cases.
Types of Open Source Harmony OpenHarmony System
Open Source Harmony is a full-scenario open-source distributed operating system designed with a component-based architecture, supporting the operation of system components on devices with RAM resources ranging from 128KiB to xGiB. Device developers can freely choose system components for integration based on the target hardware capabilities.To ensure ease of integration on different hardware, OpenHarmony currently defines three basic system types. Device developers can complete the configuration of required components by selecting a basic system type, thus enabling the development of their minimal system. The reference definitions for these three basic system types are as follows:
- Lightweight System (mini system), referred to as L0 level
This is aimed at MCU-class processors, such as Arm Cortex-M and RISC-V 32-bit devices, with extremely limited hardware resources. The minimum memory supported is 128KiB, providing various lightweight network protocols, a lightweight graphics framework, and rich IoT bus read/write components. Supported products include connection modules, sensor devices, and wearable devices in the smart home field.
- Small System (small system), referred to as L1 level
This is aimed at application processors, such as Arm Cortex-A devices, with a minimum memory of 1MiB. It can provide higher security capabilities, standard graphics frameworks, and multimedia capabilities for video encoding and decoding. Supported products include IP cameras, electronic peepholes, routers in the smart home field, and dash cameras in the smart travel domain.Product Case: Tactile Intelligence RK3506 development board, Open Source Harmony OpenHarmony + Star Flash dual ecosystem.
- Standard System (standard system), referred to as L2 level
This is aimed at application processors, such as Arm Cortex-A devices, with a minimum memory of 128MiB. It can provide enhanced interaction capabilities, 3D GPU and hardware synthesis capabilities, more controls, and richer graphical capabilities with complete application frameworks.The product case: Tactile Intelligence Purple Pi OH Harmony development board, which is at the standard system L2 level, has won the 2025 Star Development Board and multiple XTS certification honors.
Application Cases of Open Source Harmony Small System
- Home Security
A smart home security system designed based on OpenHarmony detects harmful gases, smoke, light, and rainfall. When the measured values exceed the set thresholds, it processes the current situation accordingly and reports it to the Huawei IoT platform.
- Gas Safety Monitoring
A city gas pipeline monitoring solution connects gas sensors through the OpenHarmony gateway, detecting leaks in real-time and controlling valves, supporting remote management via an app, effectively reducing the risk of gas accidents and improving emergency response efficiency.
- Medical Health Management
A smart medicine cabinet that realizes automatic inventory, counting, and real-time monitoring of medicines, addressing safety issues in hospital medicine management, achieving closed-loop management of medicine information, and supporting distributed data synchronization.
