Hello and welcome to LQ!

Yes, we will help and assist you, but just remember, we will not do your homework for you. That being said, can you show us your code so far? Or don't you have any yet?

hi,
Thank you,sure, just i want some guide, someone who is more competant than me,because,it's the first time that i practise embeded developement.
So, this is the link which describe in general how to initialize, detect, disconnect...the SDIO card version 2.00:
http://www.cs.fsu.edu/~baker/devices/lxr/http/source/linux/drivers/mmc/core/sdio.c?v=2.6.25.8#L27
and maybe, you may need the description of the card initialization flow in SD mode (exactly the function mmc_rescan):

And this is the physical specification of the SDIO card version 2.00:
