DSP软件仿真问题

新手在调试TI的FFT程序时，执行增加的64点FFT时碰到的问题Error: Can't write to data memory 0x800, check memory config [-2184]
调用如下程序：
fft.init(&fft);
RFFT32_brev(data_acq,ipcb,N);
fft.calc(&fft);
fft.split(&fft);
fft.mag(&fft);
执行到fft.split(&fft)时就弹出错误Error: Can't write to data memory 0x800, check memory config [-2184] ，在调试128点到2048点都没有碰到这个问题，只有这个64点的碰到了，有没有碰到这个问题的指导一下，不胜感激。
CMD文件如下：
