你好：
在调用fpu32_fast_supplement库中的void sincos(float32 radian, float32* PtrSin, float32* PtrCos);进行计算的时候，结果异常，于是单步进行分析。
在调用这个函数的时候，有这样的信息提示：Can't find a source file at "/home/ubnuser/ti/c2000ware/libraries/math/temp/source/fpu32/sincos_f32.asm"Locate the file or edit the source lookup path to include its location.
然后单步执行，发现在执行这个函数的时候程序跳转到地址0x08314eb
感觉这个地址异常，没有在FPUmathTables，于是查找map文件，这个函数的地址确实是0x0834eb
然后查找FPUmathTables的地址，认为这个地址应该是正常的
认为sincos应该在FPUmathTables中，但是没有
关于这个计算错误的现象，能不能给点建议，多谢

Susan Yang：
抱歉，目前手边没有板子。我会在明天测试后给您回复。
请先确认下面的信息：
您是使用的TI例程还是自己的程序？若是例程的话，请给出路径；若是自己程序的话，允许的话，请私信或上传一下工程，我们在开发板上测试一下，谢谢
,
Tobby Guo：
使用的是自己的工程，而且公司有加密系统，代码无法上传，
。
能否看一下还需要我提供什么信息，或者有什么方向的尝试，多谢
,
Susan Yang：
您需要将FPUmathTables加载到 FLASH，即在链接器命令文件中将 FPUMathTables 分配给 FLASH 部分。
