上面程序数组是4096啊，也就是4k，怎会超过0X00001000了
user4418123：
上面这个例程是TI自带的Test_FPU_RFFTF32_ADC，输入信号为signal文件，里面有4096个数。

Eric Ma：
定义的数组长度太大，对应的RAM放不下，可以把数组改小，或是把RAM合并弄成一大块。
你定义的是浮点型，相当于long，你改成int类型就没问题。

Gavin J：
另外，你的RFFTdata2/ RFFTdata3/ RFFTdata4 是定义在那个RAMLx里呢？
如果是用的 RAML5 | RAML6 | RAML7方式定义的话，建议使用楼上的方法，定义一个长的RAM字段，例如： RAML5 : origin = 0x00D000, length = 0x003000
或者，把RFFTdata2/ RFFTdata3/ RFFTdata4 还是定义在RAML5 | RAML6 | RAML7段.但对应的数组定义需要分别放在不同的.c文件里。
