hi all,
I am able to get the entry for MMC in /proc/devices and also got a node in /dev
directory with the name mmcblk0 n mmcblk0p1.
1.the problem i am facing is that when i insert MMC then system gets hang and
comes out by hiting a key.
2.when I try mount the MMC card i am geting the following error
# mount /dev/mmcblk0 /mnt/mmc/
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev mmcblk0.
yaffs: dev is 266338304 name is "mmcblk0"
yaffs: Attempting MTD mount on 254.0, "mmcblk0"
yaffs: dev is 266338304 name is "mmcblk0"
yaffs: Attempting MTD mount on 254.0, "mmcblk0"
mount: you must specify the filesystem type
any body can suggest me what i am missing and what i should do.
thanks and regards
Vivek
