Hi,Ian Campbell
  Thanks for your help.
  My CF card have a single partition with FAT filesystem.
  but when I mount this device,some errors as following:
[root@AT91RM9200DK /proc]$mount -t vfat /dev/hda /mnt/cf
hda: lost interrupt
hda: lost interrupt
hda: lost interrupt
hda: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error }
hda: task_no_data_intr: error=0x04 { DriveStatusError }
hda : bad access: block=0, count=1
end_request: I/O error, dev 03:00 (hda), sector 0
FAT: unable to read boot sector
mount: Mounting /devhda: 15680 sectors/ (8 MB)h w/1KiB Cached, CHS=245/2/32a
 Partition check:
o nhda: /mnt/cf failed: Invalid argument

 I can't mount /dev/hda1 so I use /dev/hda.

 some infomations after run command cardmgr as following:
[root@AT91RM9200DK /proc]$cardmgr
at91_pcmcia_configure_socket(): config socket 0 vcc 33 vpp 0
at91_pcmcia_configure_socket(): config socket 0 vcc 33 vpp 0
Trying to free nonexistent resource <c2a0c000-c2a0c00f>
hda: SanDisk SDCFB-8, CFA DISK drive
ide0 at 0xc2a0c000-0xc2a0c007,0xc2a0c00e on irq 3
hda: attached ide-disk driver.
