问题原因

Include包含路径错误，在输入包含路径时，最左边少了一个"，写成了

${ProjDirPath}/../../nuclei_sdk/SoC/rn831x_rn861x_dualcore_mcu/Common/Include"

解决方法

正确包含路径写法：

"${ProjDirPath}/../../nuclei_sdk/SoC/rn831x_rn861x_dualcore_mcu/Common/Include"

问题分析

1、实际错误提示中，已指示是调用GNU RISC-V Cross Assembler编译intexc_xxxx_xxxx.S发生错误，

2、在编译该文件时，加载包含文件，查看加载文件序列，可以看到除了问题文件是-ID:/....."，其他是-I"D:/....."；

3、结合错误提示syntax error: unterminated quoted string

从以上分析，很容易找到出问题的点就是intexc_xxxx_xxxx.S文件所需的GNU RISC-V Cross Assembler包含文件路径错误
