PCMCIA issues ---> cs: unable to map card memory 0x1000!

[Mathieu Bertrand]

Hi,

I'm currently working on a home made board based on a MIPS processor and a
Marvell MV64340 memory controller.
The MV64340 PCI bus 1 is connected to a TI 2050 PCI/PCI bridge connected to
a PCI/PCMCIA TI 1520 cardbus bridge.
Now, I encounter troubles using PCMCIA/pccard cards... I 've tried several
cards and the issue is the same.
I use Linux 2.6.8.

Here is my PCI bus configuration :

When I call cardmgr (from the console), I have the following infomation :
# cardmgr
cardmgr[1633]: cannot access /lib/modules/2.6.10-rc2: No such file or
directory
cardmgr[1633]:cs: memory probe 0xc0000000-0xc1ffffff: excluding

And here is the mapping of config.opts file :
include port 0x00000000-0x00000fff, port 0x00001000-0x00001fff
include port 0x00002000-0x00002fff, port 0x00003000-0x00003fff
include memory 0xc0000000-0xc1ffffff, memory 0xc4000000-0xc5ffffff
include memory 0xc2000000-0xc3ffffff, memory 0xc6000000-0xc7ffffff

I don't really know what to do.
Thank you for your precious help !
