CS_BAD_VCC Error during Card Configaration.

Hi.

I am involved in porting WLAN driver to Embedded Planet RPX-LITE
board.

I am using HHL - 2,4,2 and Pcmcia-cs (3.1.24). When i insert
D-Link DWL 350 prism2 card (intersil) my driver is invoked by
cardmgr.

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.

Where i need to do modification to configure EP socket for 3.3v?

Should i need to make any modification in m8xx_pcmcia.c?

I didn`t come across this problem when i tested my driver in
Compaq Armada notebook.

I am struck at this point. All inputs are welcome.

Thanks in advance,

Regards,
Naren

Which wireless driver are you using?

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.
