Problem with PCMCIA and RPXCLASSIC

[Matthew Locke]

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,
