求助！！！
在Ubuntu下挂载树莓派镜像
$sudo mkdir /mnt/rasp-pi-rootfs
$sudo mount -o loop,offset=62914560 2015-05-05-raspbian-wheezy.img /mnt/rasp-pi-rootfs
出现以下错误：
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

刚刚按照您的方法操作了一遍，还是不行 我用的是ubuntu 12.04 LTS
显示如下：
mount：文件系统类型错误、选项错误、/dev/loop0 有坏超级块，
缺少代码页或助手程序，或其他错误
有些情况下在 syslog 中可以找到一些有用信息- 请尝试
dmesg | tail 这样的命令看看。

看看咱俩的 2015-05-05-raspbian-wheezy.img 一样吗？我的是从这下载的：

关键是 -o offset 要正确(122880*512=62914560)，-t ext4 文件系统类型要正确
