TI中文支持网工程师们，你们好！
问题：在仅添加串口输出语句下，测试DSPF_sp_fftSPxSP_674_LE_ELF工程时，程序卡在了以下语句，没有继续往下执行。
DSPF_sp_fftSPxSP( N, &ptr_x_i[0], &ptr_w[0], ptr_y_i, brev, rad, 0, N);
具体情况：
（1）一开始编译不成功，以上语句也没有高亮，按F3也无法追踪到对应头文件中。把_d.c文件中对上述函数的声明注释掉后，即高亮，可追溯，编译成功；
（2）工程includes目录下有一个路径为灰色，不知是否有关，对应参数如下
（3）生成的map文件中，应该有引入对应的执行语句，详情见附件的119行；

（4）程序采用starterware提供的bootloader和该fft运行。

谢谢工程师们！
Nancy Wang：
单步进入DSPF_sp_fftSPxSP可以调试吗？
,
user6446474：
你好，Nancy Wang！
还没购买仿真器，无法进行单步调试。
请问我列出具体情况的（1）、（2）点，特别是（2）点，会导致上述问题发生吗？
DSPF_sp_fftSPxSP函数是用汇编写的，我能找到对应asm文件，是否需要引入到工程中？
,
Nancy Wang：
不知道你是怎么调试的，最好是用仿真器调试，如果是缺少头文件话的编译的时候就会有问题。
