摘　　要：具有相同的RISC-V指令集的处理器实现并不相同。本文将针对基于RISC-V开源指令集的处理器芯片GD32VF103 MCU,介绍FreeRTOS在IAR EWRISC-V编译和开发环境下的移植过程。采用RTOS后,嵌入式系统很难监控系统的运行时行为、发现应用存在的问题,本文基于Tracealyzer分析工具直观地跟踪系统行为,分析系统中可能的错误,提高代码的鲁棒性。Processor implementations with the same RISC-V instruction set are not the same.This paper will introduce the migration process of FreeRTOS under IAR EWRISC-V environment for the processor chip GD32VF103 based on RISC-V open source instruction set.With the RTOS,it is difficult to monitor the runtime behavior of the system and find problems in the application.This article will use the Tracealyzer analysis tool to visually system behavior,analyze possible errors in the system,and improve the robustness of the code.
