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??
