Research on the Porting and Adaptation of OpenHarmony Based on the SCDAYU800A Development Board

文章详细介绍了针对润开鸿鸿锐开发板SCDAYU800A的OpenHarmony操作系统的移植适配过程。润开鸿鸿锐开发板SCDAYU800A基于平头哥高性能RISC-V架构曳影TH1520芯片，具备强大的AI算力和丰富的功能接口。通过对OpenHarmony的适配，实现了从产品定义、工具链适配到内核移植、驱动适配等关键环节的完整流程。并重点探讨了RISC-V架构下针对标准系统Linux内核的移植以及触摸屏驱动的开发，为基于RISC-V架构的嵌入式系统研究提供了实践参考。This paper provides a detailed introduction to the porting and adaptation process of the OpenHarmony operating system for the RunKaiHong Hongrui development board SCDAYU800A. The SCDAYU800 development board, based on the Pingtouge high-performance RISC-V architecture Yieying TH1520 chip, features powerful AI computing capabilities and a rich set of functional interfaces. By adapting to OpenHarmony, the entire process from product definition to toolchain adaptation, kernel transplantation, and driver adaptation has been successfully implemented. The paper focuses on the adaptation of the transplantation of the Linux kernel under the RISC-V architecture, and the development of the touchscreen driver, providing practical references for embedded system development based on the RISC-V architecture.
