Re: 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!?

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/<board>.h:
                        /* define IO_BASE for pcmcia */
                        #define _IO_BASE 0x80000000
                        #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/200005/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
