use University Program SD Card ip core - DE2

Hi all;

I am a student from China,I'm using the University Program sd card ip core in my nios ii ,I have read the SD_Card_Interface_for_SoPC_Builder.pdf and use the program in the pdf. But the function alt_up_sd_card_is_Present() always return 0,seems that there is no sd card in my board ,

PS: device_reference = alt_up_sd_card_open_dev(SD_CARD_INTERFACE_NAME) suceeds.

:eek:

Any help would be greatly appreciated. It's quite curious.

I'm using quartus 11.1sp2

    Hi,

    u said -"seems that there is no sd card in my board" -

    There is no SD card by default on the board on DE2. Insert it into the slot at the bottom correctly and check again .

    Have you included the SD Card module on your SOPC Builder / Qsys project?

    Have you used the alt_up_sd_card_open_dev function to open your device first?

    Could you please tell me how did you configure your system step by step. I have added University IP cored(SD card) to my project and in nios ii I checked with the provided programme in the manual. In the nios ii project there are no errors and when I print the sd card reference it refers to a place in SDRAM. Also alt_up_sd_card_is_Present() function is not working. But there are no errors. Can you give me any help. Thank you very much...
