Subject: 16-bit PCMCIA resource allocation
I am having difficulty getting 16-bit PCMCIA cards to work on a custom
MPC8245-based board. I am running kernel 2.6.14.2 with pcmciautils-014.
I have successfully run the network off a 32-bit PCMCIA network card so
I am certain that the interface to the PCMCIA socket is functional. I'm
thinking it is just a resource allocation issue but I am having
difficulty understanding how it is supposed to work. When I insert the
card or call "pccardctl insert" I receive the error "cs: unable to map
card memory."
>From following the source I can tell that the error occurs when the
kernel is trying read the cards CIS and it fails to allocate/map memory
to do so. Do I need to tell the kernel to reserve a block of memory for
16-bit PCMCIA cards? I assume this would be from the PCI busses address
space. Is this done using the "/etc/pcmcia/config.opts" file? I was
under the impression that I didn't need this file for a Yenta socket in
a PPC environment. Could is be the way my PCIbus is setup? ...
Any hints are greatly appreciated.
