Unable to access PCMCIA with O2 Micro OZ711MP1/MS1

Mon Feb 4 09:01:44 EST 2008

Hello,

I hope I am contacting the appropriate list for this. Please, let me 
know if I should search somewhere else.

There seems to be a problem accessing PCMCIA cards with O2 Micro 
OZ711MP1/MS1 Controller and it would be really great if I could get some 
hints from this list to get around it.

On a Fujitsu Siemens Celsius H240 a 2.6.22-3-amd64 kernel from Debian 
testing is in use. PCMCIA utilities for Linux 2.6 version 014-4 are 
installed. I concatenated the the output of lspci and lshal below.

When I insert a CardBus adapter, for instance a CNET CNF401 fast 
ethernet, everything works fine and the adapter becomes available to the 
system -- in this example the NIC with working LAN access. The lspci and 
lshal output then reflects the new hardware.

When I insert a PCMCIA adapter, for instance a 3com 3CCE589EC or an 
compact flash adapter, almost nothing happens: In the case of the 3com I 
just get (dmesg):

	pccard: PCMCIA card inserted into slot 0

In the case of the compact flash adapter at the first insert dmesg gives:

pccard: PCMCIA card inserted into slot 0
cs: memory probe 0x0c0000-0x0fffff: excluding 0xc0000-0xfffff
cs: memory probe 0x60000000-0x60ffffff: excluding 0x60000000-0x60ffffff
cs: memory probe 0x88000000-0x8fffffff: excluding 0x88000000-0x8fffffff
cs: memory probe 0xa0000000-0xa0ffffff: excluding 0xa0000000-0xa0ffffff
cs: memory probe 0xf0300000-0xf03fffff: excluding 0xf0300000-0xf03fffff

Later dmesg issues just "pccard: PCMCIA card inserted into slot 0"

In both PCMCIA examples the lshal output doesn't change, in the lspci 
output the original line:

	BridgeCtl: Parity- SERR- ISA- VGA- MAbort- >Reset+ 16bInt+
	PostWrite+                                  ^^^^^^

changes to:

	BridgeCtl: Parity- SERR- ISA- VGA- MAbort- >Reset- 16bInt+
	PostWrite+                                  ^^^^^^

In the case of the compact flash neither "modprobe ide_cs" nor "modprobe 
pata_pcmcia" yield anything -- not even in dmesg.

As I do not want to access a SmartCard I did not try the o2scr driver 
from gna.org/projects/o2scr.

Now the command output will follow, but before that:

Best regards, Alexander.
