Hi,
[We are using Hard HAt Linux (Kernel 2.2.14) and PCMCIA
patch for pcmcia-cs-3.1.19]
I am trying to get IBM microdrive based on PCMCIA up on CLLF
board(RPXCLASSIC).
With _IO_BASE=0x80000000(in mpc8xx.h), kernel doesnt come up at all,
just prints a kernel panic msg about access to memory..
So, we tried changing the IO_BASE to 0(this was the value in older
versions before the patch of pcmcia-3.1.19 was put up).
With this as IO_BASE the kernel comes up and we get the shell prompt
also.(BUt what is the correct value of _IO_BASE for cllf rpxclassic
board)?
Now when trying to get the IBM microdrive up as an ide disc, when we
invoke cardmgr(after doing insmod of the pcmcia basic modules),
the following error is shown..

two patches need to be applied to the kernel to get PCMCIA ide cards to
work. Did you apply both patches? they are on
ftp://ftp.mvista.com/pub/area51/ppc_8xx
That should be the only issue. I have not tested the IBM microdrive
specifically, but other IDE flash cards work fine.
since the RPX-lite and cllf do not have PCI, 0x80000000 will work.

Hi Mathew Locke,
Thanks for the response, and the new status...
kernel version: 2.2.14
pcmcia-c version: 3.1.22
We have applied both the patches to the kernel put up on your site.
The pcmcia-3.1.22 has compilation problems as the mpc8xx_bdinfo is not
defined. It is used only for the frequency, hence we hard coded it to
40MHz(which is our boards operating freq).
Then we gave _IO_BASE = 0x80000000
This still did not work and the kernel panics. We had to comment out
a line in ll_rw_blk.c( where and outb_p is called)..
After this the kernel comes up.
Wpe suspect some goof up in the file: arch/ppc/kernel/m8xx_setup.c
Here ATA_FLASH is defined to 1.(and the comment is:
/* Define this to make a PCMCIA ATA Flash card work.
*/
)
But with this define, the function rpx_pcmcia_config() doesnt get
called at all.
Does anyone have a patch for this file?
Also, what should be the values in the config.opts for this?
I HAVE READ IN THE MAILING LIST from Dan dated TUE 02, may 2000
that he has successfully used IBM Micro drive with MPC860 PCMCIA.
has anybody got the detail information ?
thanx
Govindan

yeah, i forgot to export that in my patch.

So, IO_BASE = 0x80000000 does work, ll_rw_blk.c is an unrelated bug.

It may be a little confusing, but since it works for me I doubt there is a
goof up. The confusing part is that there is code in there to bypass card
services for ATA cards. Instead of deleting it, I left it so that people
who don't want the overhead of card services (my guess is that it doesn't
really affect perfomance that much) don't have to use it.
>Does anyone have a patch for this file?
you have the patch that works.
>Also, what should be the values in the config.opts for this?
config.opts is not used for the 8xx.
you can send me a microdrive and I will figure out what the problem is.

I don't think Dan uses card services. He has code in the kernel that
connects the ide driver directly to the 8xx pcmcia controller.

What are you guys using for a kernel? This outb_p "bug" was fixed
in ancient times (or you didn't properly configure the kernel).

Yes, this works. It sounds like you are mixing the internal ATA hack
with card services. You can't use both........

That's right, no card services when I wrote that message. I just
used the PCMCIA interface as a dedicated ATA interface. The purpose
was simply to verify the hardware would work correctly, and to provide
a method for embedded systems to use this interface directly without
card services.

Hi..
We got the IBM microdrive on pcmcia up on RPXclassic
with the changes(given in patch file as attatchment).
Kernel: 2.2.14
pcmcia-cs:3.1.22
This, unlike dan's implementation, uses the card
services also. There are mainly 3 changes:
1. _IO_BASE
2. Hooking the IRQLVL of PCMCIA PGCR to 9(9 is used by
ide.. else we get a lost interrupt error).
3. ide_ack_intr to clear PCSR.
