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
