使用SD卡和Flash做2个磁盘，将SD或flash做为卷0，程序都可以正常访问目录，文件，另外可以对卷1进行格式化，但是却访问不了卷1的目录；有没有知道什么问题的？
void ShowSDFiles(u8 index)
{
FILINFO finfo;
DIR dirs;
char path[100] = {""};
printf("\nSD file system starting! \n");
disk_initialize(index);
printf("f_mount %d\n", f_mount(index, &fs));
printf("f_mkfs %d\n", f_mkfs(index, 0, 512)); // SD 卡时为4096
printf("----------------------------------------------------\n");
printf("f_opendir(&dirs, \"/\") = %d;\n", f_opendir(&dirs, "/"));
if(f_opendir(&dirs, path) == FR_OK)
{
while(f_readdir(&dirs, &finfo) == FR_OK)
{
if(!finfo.fname[0]) break;
if (finfo.fattrib & AM_ARC)
{
printf(" file name is: %s ", finfo.fname);
printf("file size is: %d \n", finfo.fsize);
if(File_type_Check((u8 *)finfo.fname, "txt"))
{
printf("file contex is:");
res = f_open(&fsrc, finfo.fname, FA_OPEN_EXISTING | FA_READ);
while(1)
{
memset(buffer, 0, sizeof(buffer));
if(f_gets(buffer, 512, &fsrc))
{
printf("%s", buffer);
}
else break;
}
f_close(&fsrc);
}
}
else
{
printf("Path name is: %s\n", finfo.fname);
continue; //break;
}
}
res = f_open(&fsrc, "armjishu.txt", FA_CREATE_ALWAYS | FA_WRITE);
res = f_write(&fsrc, &armjishu, sizeof(text), &bw);
f_close(&fsrc);
else
{
printf(" err: f_opendir\n");
}
printf("----------------------------------------------------\n");
f_mount(index, NULL);
}
