I'm using Kernel 4.1.0 btw.

I tried to find the filesystem of /dev/mmcblk0p1 with
root at OpenWrt:/# tune2fs -l /dev/mmcblk0p1
tune2fs 1.42.12 (29-Aug-2014)
tune2fs: Bad magic number in super-block while trying to open /dev/mmcblk0p1
Couldn't find valid filesystem superblock.

root at OpenWrt:/# fdisk
Disk /dev/mmcblk0: 3875 MB, 3875536896 bytes
235 heads, 20 sectors/track, 1610 cylinders
Units = cylinders of 4700 * 512 = 2406400 bytes

        Device Boot      Start         End      Blocks  Id System
/dev/mmcblk0p1               1        1610     3781632   6 FAT16


How may I mount this partition?
