Hi,
    Just going through the sdio specs and ossman's patch.


   What are these functions and thier numbers in CMD 53

   Does that mean an SDIO Card can support upto 8 different functions?.

   An sdio card can be used as a wlan and camera (if it supports 2
functions wlan and camera).

  Is it like that?. Because i have not come across a card which
supports more than one function.

  What does "function" mean - does that mean some kind of firmware
inside the card or some kind electronics.

  I dont understand.


Thanks and Regards,
Jo

Exactly.
It supports one or zero memory functions, and up to 7 (8?) IO functions.

AIUI, there are at the moment cards with memory and wifi.

I have wondered about expander cards - a card with a microcontroller to 
do enumeration and several sockets.
This is quite complex though.
