TMS320F28027: 工程编译的时候有关于 ".cio"的警告，下载代码后点击运行键会有提示，具体如下：

1.Description Resource Path Location Type #10247-D creating output section ".cio" without a SECTIONS SPWM(ONLYOPEN) HF C/C++ Problem

2.Invalid CIO command (255) in the CIO buffer at address (0x3F0000) was not recognized. Please check the device and program memory maps.

但我在整个工程中并没有搜到cio 请问这怎么解决？

CMD文件中并没有cio的定义
