can not mount 4gb card of transend

dear all :

 I have one question.

I have one sd card which is 4gb  card  of transend .when I want to mount this card to linux ,

 mount -t vfat  /dev/mmcblk0p1 /mnt/sddisk/
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev mmcblk0p1.
mount: wrong fs type, bad option, bad superblock on /dev/mmcblk0p1,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

Note 1) I have added SDHC support into my linux,

2) I can mount any other card such as scandisk card (4gb sdhc card ) kinston card(4gb sdhc card ,16gb)

3) I have changed transcend card into FAT32 under win XP

4) The csd structure version of transcend is 2.0 . But the C_SIZE is 512 times of other card.

5) My environment is :DM365 + MontaVista(R) Linux(R) Professional Edition 5.0.0 (0801921)

 

 Thanks a lot!

    Can you try re-partitioning the card on the DUT itself? You can use fdisk to remove existing paritions and create fresh one. Then use mkfs.vfat to create a vfat partition.

    Also, just to make sure the card is OK, can you try if a Linux PC is able to mount it correctly?

    SDHC support is natively available on DM365 as part of the PSP 3.01 release (2.6.32-rc1 kernel). Can you download a pre-built uImage of that release and do the same test to ensure the SDHC changes done by you are not the issue?

    Thanks,
