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
