Pin assignment for the SD Card on DE2-70

I have problem to find the pin assignment for the SD-card on the DE2-70 development board. I want to connect to the SD-Card without using the Nios II.  

Anyone have a clue which pin to use?

Hi... 

 

just wondering: can those pins also be used for the DE1 board? I've been having the hardest time finding any documentation on that... 

 

Thanks a lot,

I am trying to interface the University IP SD Card Interface with the DE0 board. 

As far as I can tell there are two PDF's, one from 2009 and the other from 2011 

Both come up on Google, and it took me a while to realise there were two. 

The 2009 version lists the pins for the DE1, 2 and 3. The 2011 version lists DE0, 1, 2, 2-70, 2-115, 3 and 4.

I'm struggling to get the IP to detect the device. Will start a new thread now. =)
