通过EMIF16将外接FPGA输出的信号传给DSP，请问下能不能提供个EMIF的例程？

C66X EMIF测试例程：http://www.deyisupport.com/question_answer/dsp_arm/c6000_multicore/f/53/t/6242.aspx
                                                                          

你好Andy Yin,
我试了一下你提供的例程,编译之后出现了跟原帖一样的问题.

如原帖所说，该例程是基于C6614，如果使用C6678的话，两者底层CSL的一些宏定义不一样，你需要在C6678 CSL中找到相应的宏替代。
                                                                          

Andy Yin1你好,
我将csl宏定义更正,现在这部分没报错了(我将CE0改成CS2,这样对应正确么?比如CSL_EMIF16_AWCCR_CE0WAIT_SHIFT改成CSL_EMIF16_AWCCR_CS2WAIT_SHIFT，另外其他参数比如程序中的i也需要改么?)
现在我的程序仍有错误,如下所示
Description Resource Path Location Type
identifier "DEVICE_EMIF_NAND_ALE_OFFSET" is undefined flash_nand.c /EMIF/src/FLASH line 456 C/C++ Problem
identifier "DEVICE_EMIF_NAND_CLE_OFFSET" is undefined flash_nand.c /EMIF/src/FLASH line 451 C/C++ Problem

struct "" has no field "NFECCCE0" flash_nand.c /EMIF/src/FLASH line 615 C/C++ Problem
但是比如我去源码中找,比如第一个提示错误NAND_ALE_OFFSET,因为调用了flash_nand.h, 所以是定义了的,能直接跳到
#define NAND_ALE_OFFSET     DEVICE_EMIF_NAND_ALE_OFFSET, 但是为什么还会提示错误？
谢谢解答。
