ccs5.5 debug之后出错，如何解决？

如图，点运行之后出现如下错误

文字版：
TMS320C55x: AutoRun: Target not run as the symbol "main" is not defined

TMS320C55x: Can't Run Target CPU: Check the linker command file / map file for any part of the program going into reserved area and correct the problem when Program Counter is 0x80 NOTE: Reset the target, reload the corrected program and continue execution

TMS320C55x: Can't Single Step Target Program: Unknown Fatal Error
附上.cmd选用的是simulator环境，没有用板子

求各位解答怎么改错
