Problem with PCMCIA and RPXCLASSIC

[Govindan]

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

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,


[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..

Any idea what the problem is..

Thanks in advance,
