Re: Re: CS_BAD_VCC Error during Card Configaration.

Hi,

After i made the change to ignore mismatch in Vcc....my call to
cardservices(RequestIO) is
failing and the error returned is Resource in use.

But i neglected this failure and procedded..so now card is
configured and next failure
occured when i try to write to WLAN card register. In this case
Baseaddress returned
is 0 and i have done the modifications to add _IO_BASE to the base
address. (As mentioned
in mail archives).

what might be wrong for RequestIO failure??

Thanks,
Naren

But as i found through debug message, socket is configured for
5volts and the CIS read from my card wants 3.3V. So my
Config()
routine is failing since there is a mismatch in configured Vcc
and
Requested Vcc. and Kernel is crashing.

You are using a 3.3V card in an 5V socket. If the card can do
this - and I think Prism 2 can - you  can bypass the code which
checks if the Vcc is correct. You will maybe find it if you look
in the WLAN drivers source code and search for conf.Vcc.

Have you checked which is really the value used for _IO_BASE? It is
configured several times in the kernel. The value in
include/asm/<board>.h has to be correct.

It maybe helps if you post the error and tell us which kernel and board
you use.
