PCMCIA Problems

PCMCIA Problems

[clark]

	Hello,

	I seem to be having trouble with getting pcmcia-cs working. I am using a
custom board with a MPC850 running PPCBoot and HardHat Linux. Everything
seems to work fine up until Cardmgr loads. I know I need to define _IO_BASE
and its size but I'm not sure how to figure out what to set it to. I have
tried to set it to various values 0x80000000, 0xEC000000, 0xC0000000, and
0xD0000000 all with no luck. Do I need to do more than declare it?

here is typical output.

	With a silly scope I can see the pcmcia device assert the RDY/BSY_B line

explodes in my face.

Any help apprieciated, Many thanks in advance.

I set _IO_BASE to 0x80000000 and it worked fine in 2.2.14.  My patches
are on our ftp site.

pcmcia problems

[Fend, Matthias]

hello everybody,

i'm trying to run pcmcia service (ISDNCard (Fritz PCMCIA V2.0) on a custom
mpc860 board.

i started with pcmcia-cs-3.1.33 i changed the  PCMCIA_MEM_WIN_BASE in
m8xx_pcmcia to 0xE0000000
i also implemented the adapter methods for the voltage selection

in /arch/ppc/mm/init.c  MMU_init(void)
i added the line
  ioremap(0xE0000000,0x1000);

i load the modules pcmcia_core.o ds.o and m8xx_pcmcia.o

the iopins (CD,VS,WP..) seem to work fine (tested with cardctl status 0)

but if i try to run
> ./cardctl ident 0
i only get:
> no product info available
> function: 2 (serial)
>sh-2.03#

if i turn debug on i get this message
cs: overrun in get_next_tuple for socket 0


so now it don't know if it is a software problem or a hardware problem...

Q1: any ideas what i could try in next step

Q2: what is the difference between MEM_BASE and IO_BASE

Q3: cardmgr always think that he detects an anonyoumous memory and start this
service .. is this caused by the
bad cis reading or is this another problem?

thx matthias

Re: pcmcia problems

[Leiying Du]

Q3. You are right. This is caused by the bad CIS or you do not have CIS info
on the card at all. Try to use the dump_cisreg & dump_cis utilities to see
what's on your card.
