不好意思，忘了回复楼主了。
static const char * FR_Table[]=
{
"FR_OK：成功", /* (0) Succeeded */
"FR_DISK_ERR：底层硬件错误", /* (1) A hard error occurred in the low level disk I/O layer */
"FR_INT_ERR：断言失败", /* (2) Assertion failed */
"FR_NOT_READY：物理驱动没有工作", /* (3) The physical drive cannot work */
"FR_NO_FILE：文件不存在", /* (4) Could not find the file */
"FR_NO_PATH：路径不存在", /* (5) Could not find the path */
"FR_INVALID_NAME：无效文件名", /* (6) The path name format is invalid */
"FR_DENIED：由于禁止访问或者目录已满访问被拒绝", /* (7) Access denied due to prohibited access or directory full */
"FR_EXIST：由于访问被禁止访问被拒绝", /* (8) Access denied due to prohibited access */
"FR_INVALID_OBJECT：文件或者目录对象无效", /* (9) The file/directory object is invalid */
"FR_WRITE_PROTECTED：物理驱动被写保护", /* (10) The physical drive is write protected */
"FR_INVALID_DRIVE：逻辑驱动号无效", /* (11) The logical drive number is invalid */
"FR_NOT_ENABLED：卷中无工作区", /* (12) The volume has no work area */
"FR_NO_FILESYSTEM：没有有效的FAT卷", /* (13) There is no valid FAT volume */
"FR_MKFS_ABORTED：由于参数错误f_mkfs()被终止", /* (14) The f_mkfs() aborted due to any parameter error */
"FR_TIMEOUT：在规定的时间内无法获得访问卷的许可", /* (15) Could not get a grant to access the volume within defined period */
"FR_LOCKED：由于文件共享策略操作被拒绝", /* (16) The operation is rejected according to the file sharing policy */
"FR_NOT_ENOUGH_CORE：无法分配长文件名工作区", /* (17) LFN working buffer could not be allocated */
"FR_TOO_MANY_OPEN_FILES：当前打开的文件数大于_FS_SHARE", /* (18) Number of open files > _FS_SHARE */
"FR_INVALID_PARAMETER：参数无效" /* (19) Given parameter is invalid */
};
返回0C的话就是 "FR_NOT_ENABLED：卷中无工作区", 有可能是USB对FatFS的接口函数有问题。 |
