PCMCIA on an MPC860
Hi, Alex:
You might want to use 'ksymoops' to find more useful information from this
oops.
It's smart to tell you which routine caused the trouble.

PCMCIA on an MPC860
I've not used the driver together with a 2.4 kernel,
so I'm not sure how well modules from pcmcia-cs plays
with pcmcia stuff in the kernel.
Linux-2.4.19 has a version of the driver that
Matthew Locke modified and bugfixed. Maybe that one
works better with 2.4 kernels.
What happens if you decode the OOPS?
To get symbols, use the file System.map from
the kernel together with the map generated by
"insmod -m".
Or use /proc/ksysms from the running system.
"cardctl ident" and "cardctl status" only reads
the CIS and checks the pin status. (Correct me
if I remember wrong).
I think it will be the ide-driver that starts
accessing the IO-space. Maybe that doesn't work.

I suggest you switch on PCMCIA_DEBUG in CS, put some extra printk's into ide_cs.c _and_ in ide_init_hwif_ports() to find out which addressen are used! Can you backtrace 'cardmgr' ?

The crash occurs in the ide_cs client. The order of calls is: (CARD INSERTION) -> ide_event() -> ide_config() -> ide_register(). The crash occurs somewhere in ide_register(), but I find reading through that code a bit hairy as I don't really know anything about IDE myself. I suspect that I've got a problem with byte ordering. This would explain the problem I get when I insert an ethernet card. When I do this, the client 3c574_cs tries to write a command to a register on the card, and read another register to determine when the command has been completed - however, this never happens. This could be a result of performing reads and writes in the wrong order. In Magnus' email (http://lists.linuxppc.org/linuxppc-embedded/25/msg00227.html) he talks about Endianness. However, I've been through the source files he talks about (my kernel is linux-2.4.4-2001-11-24) and all of the changes he refers to are already there. Any ideas?

PCMCIA on an MPC860
Alex,
actually I had the Card Service running on MPC855/860 systems with Ethernet,
WaveLAN and ATA Cards.
It's a while back so I try to remember realy hard now!
I had this problem too.
1.) Did you try another PC Card, i.e. ethernet?
2.) How are your settings for IDE in your kernel configuration?
3.) I think I remember that I had to change something about the request_irq /
request_8xxirq.
I think the oops comes because the driver can't request the irq!!!
Could you please show us you're oops!?

PCMCIA on an MPC860
Steven,
Thanks for your reply. I did try an ethernet card as well. With that
I got a different problem -
after insmodding the client driver I got the following error message:
eth1: command 0x5800 did not complete!
I also got this error whenever I tried to ping.
My Kernel IDE config is as follows:
# ATA/IDE/MFM/RLL support
#
CONFIG_IDE=y
#
# IDE, ATA and ATAPI Block devices
#
CONFIG_BLK_DEV_IDE=y
# CONFIG_BLK_DEV_HD_IDE is not set
# CONFIG_BLK_DEV_HD is not set
CONFIG_BLK_DEV_IDEDISK=y
(everything else IDE related is not set)
Here's my Oops:

PCMCIA on an MPC860
All,
Has anybody had any luck getting PCMCIA to work on an MPC860?
I have a custom MPC860 board, with a single PCMCIA socket connected to Slot B.
This is what I have
so far done:
1.
Downloaded pcmcia-cs-3.2.0.tar.gz
2.
Added board specific definitions in modules/m8xx_pcmcia.c for
hardware_enable()
hardware_disable()
voltage_set()
socket_get()
3.
Cross compiled for the 8xx.
4.
In my kernel (linux-2.4.4-2001-11-24 from Denx) I added the following lines
include/asm-ppc/.h:
/* define IO_BASE for pcmcia */
#define _IO_BASE 0x8000
#define _IO_BASE_SIZE (1024*64)
arch/ppc/mm/init.c:
void __init MMU_init(void) {
...
ioremap(_IO_BASE,_IO_BASE_SIZE);
...as suggested by Magnus Damm in
http://lists.linuxppc.org/linuxppc-embedded/25/msg00227.html
HOWEVER,
5. When I boot my board with a Flash card in the PCMCIA slot, and I run:
/etc/rc.d/rc.pcmcia start
I find that ide_cs.o causes an Oops when it calls ide_register().
"cardctl status"
and "cardctl ident" work though.
Can anybody suggest what I'm doing wrong?
Thanks in advance,
Alex
