Using SD-Card reader on DE1 board (with Nios)

Hello all,

I have the same problem with quartus 11.

When I compile the project I get the error: Error: Node instance "packet_memory" instantiates undefined entity "Altera_UP_SD_Card_Memory_Block"

But when i add the files Altera_UP_SD_Card_Memory_Block to the project, I can compile the project, but when I run it, sd doesn't work. Just at if(alt_up_sd_card_is_Present()) and doens't work

In quartus 13 works fine. But I need run it on quartus 11.

Any solution?

Thank you
