修改了存放fft数据的地方，我感觉还是FFT部分配置的有问题在RAM里是可以的，固化到Flash里就不行了，其他部分都可以在FLASH正常运行
烧写的时候还会出现错误
Warning: This program contains initialized RAM data.
It may run successfully under Code Composer Studio
but not as a standalone system because of this. If
your Flash program requires initialized data in RAM,
you will need to write Flash code to initialize RAM memory.
Erase/Program/Verify Operation succeeded
**** End Erase/Program/Verify Operation. ***
把和FFT相关的部分去掉就不会出现这个警告
