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.
