不知道为什么刚开始一直没有成功，正当准备放弃的时候自己又好了，总之是十分诡异啊。
首先去fatfs官网下载最新版的文件，最新版是R0.14a，链接如下：

然后是w25q16的驱动文件前面已经测试完毕了，看前面的测评**即可。
全部分fatfs文件包如下：
我们需要进行的是diskio.c文件的修改和ffconf.h文件的配置。
首先需要进行的是头文件的包含，不知道为什么头文件放在diskio.c中老是报错，我干脆都放在diskio.h中了。

首先是当配置为#define FF_FS_NORTC 0的时候，是需要get_fattime这个函数的，我们在ffconf.c中人为的配置get_fattime这个函数。
