PCMCIA / compact flash / au1x00

[Aeschbacher, Fabrice]

Hi,

[kernel 2.6.20.7 / mips]

I am having trouble using a compact flash connected to a PCMCIA socket
on an Alchemy au1550 board (mips).

The CF seems to be recognized:

  # insmod au1x00_ss.ko

  => dmesg output:
    pccard: PCMCIA card inserted into slot 0
    pcmcia: registering new device pcmcia0.0

  # pccardctl ls          
  Socket 0 Bridge:        [au1x00-pcmcia]         (bus ID:
au1x00-pcmcia.0)
  Socket 0 Device 0:      [-- no driver --]       (bus ID: 0.0)

  # pccardctl info
  PRODID_1="TRANSCEND"
  PRODID_2="TS2GCF120"
  PRODID_3=""
  PRODID_4=""
  MANFID=000a,0000
  FUNCID=4

  # pccardctl status
  Socket 0:
    3.3V 16-bit PC Card
    Subdevice 0 (function 0) [unbound]

Problem: I can't access the CF by its device (hda):

  # fdisk /dev/hda
  Unable to open /dev/hda



Here is the relevant part of the kernel config:
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDECS=m
CONFIG_PCCARD=y
CONFIG_PCMCIA_DEBUG=y
CONFIG_PCMCIA=y
CONFIG_PCMCIA_IOCTL=y
CONFIG_PCMCIA_AU1X00=m

Neither hotplug nor udev is installed (I only installed
/sbin/pccardctl).

I know cardmgr is no more used in recent kernels. Anyway, if I try to
run it, I become following result:

  # cardmgr
  cardmgr[976]: watching 1 socket
  cardmgr[976]: could not adjust resource: IO ports 0xc00-0: Invalid
argument

and following output in dmesg:
  ds: ds_open(socket 0)

Can someone tell me what I missed?

Note: the CF used to work correctly with a kernel 2.4.26
