mounting sd card

Can't mount SD card.

[root@FriendlyARM /]# mount -t ext3 /dev/mmcblk0 mnt/sd_card
mount: mounting /dev/mmcblk0 on mnt/sd_card failed: Invalid argument

No, there are no partitions on the card. Just an ext3 file system.

[root@FriendlyARM /]# mount -t ext3 /dev/mmcblk0p1 /mnt/sd_card
mount: mounting /dev/mmcblk0p1 on /mnt/sd_card failed: No such file or
directory

Card leaving and coming is recognized.

Any suggestions?

Thanks.

Check /dev/mmcblk0p1 node is exists? If no, then check mdev or udev utils
in your filesystem

I tried the same command you use but without -t option. it gives me a
warning but it works fine for me
[root@FriendlyARM /]# mount /dev/mmcblk0p1 /mnt/sd_card

Check "/proc/filesystems" if it lists the ext3 filesystem as supported. If
not, re-build your kernel with ext3 support.
