Unable to mount SD memory card in linux 2.6.15 kernel

[gangireddy]

Hi,

I am trying to mount a SD memory card in linux 2.6.15 kernel. The slot I am using is Arasan PCI card which has a SDIO slot. When I inserted the module sdmmc.ko corresponding to Arasan card, in the dmesg I am able to see the card information like manufacture id, memory size, 4 bit etc.

But, the device is not shown in the /dev/. I tried to do the following steps but it has given me the error shown below.

# mknod /dev/sdmmc0p1 b 252 0 (because in the /proc/devices the device is shown at 252)
#mount -t vfat /dev/sdmmc0p1 /mnt/

I am getting this error when I saw in dmesg.

FAT: Bogus number of reserved sectors
VFS: Cant' find a valid FAT filesystem on dev sdmmc0p1

But the issue is with the card as the same card is working in 2.6.18 kernel. Please let me know whether there was any problem in the way I am mounting the device or is there a different way to mount the device.

Thanks,
Gangi

I find that the best way to use SD cards with Linux (though Ubuntu on my laptops work just fine with the built-in sd reader) is to use a USB thumb drive sd reader. That way, it looks to the system as a standard USB thumb drive - you just plug it into a USB port. I don't even bother with the SD readers any more, generally.
