工具与软件：

大家好！

当使用 HalCoGen 生成的 FreeRTOS 端口尝试在我的项目中进行软件复位时、会遇到数据中止异常。

当 RTOS 未运行时、重置效果很好、但一旦涉及到 FreeRTOS、就会出现问题。

相关代码如下：

/** @file sys_main.c 
*   @brief Application main file
*   @date 11-Dec-2018
*   @version 04.07.01
*
*   This file contains an empty main function,
*   which can be used for the application.

有没有人遇到过这种情况或对使用 FreeRTOS 时软件复位失败的原因有任何见解？非常感谢您提出任何建议！

提前感谢您！
