【求助】mount 文件系统的问题

elvispl

谁知道mount SD卡时出现下面的错误是什么意思啊？
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev spi_mmc.

我在一个网站上看到说：
logread will normally give some clue as to the nature of the problem - for example in the above case /dev/sda3 was not a FAT partition:

kernel: FAT: bogus number of reserved sectors
kernel: VFS: Can't find a valid FAT filesystem on dev sda3.

但是我已经在windows下格式化成fat格式啊

你的mount命令是怎么写的？

elvispl

mount -t vfat  /dev/mmc /mnt/mmc
