鸿蒙系统在Cortex-M内核架构上的移植和应用

Transplantation and Application of HormonyOS on Cortex-M Kernel Architecture

鸿蒙是华为推出的面向全场景的操作系统,已在华为手机上成功应用两年多,但在各种嵌入式市场主流的芯片架构上鸿蒙操作系统的应用还比较少。介绍了在ARM Cortex-M4架构的芯片STM32F405RGT6上移植鸿蒙轻量型系统的全过程和关键代码修改步骤,并通过串口输出实验验证了移植系统的性能,实验证明鸿蒙系统具有实时性好、易剪裁等优点,比较适合作为微小型智能终端的底层软件。

HarmonyOS is an all-scene operating system launched by Huawei.It has been successfully applied in Huawei mobile phones for more than two years,but it is still rarely applied in the mainstream chip architectures of various embedded markets.This paper introduces the whole process and key code modification steps of the lightweight system transplanted to the chip STM32F405RGT6 of ARM Cortex-M4 architecture,and verifies the performance of the transplanted system through the serial port output experiment.The experiment proves that the system has the advantages of good real-time performance and easy tailoring.It is more suitable as the bottom software of micro intelligent terminal.
