Need Help For Learning Sd Card Ip Core

Hi, I want to make a SD CARD SPI MODE Host controller. I tried to make it using vhdl code only. But in the middle of it , I realized that it was to complex without using SOPC builder and NIOS II. Since ,I'm new using iP core. I don't know how to start.

I'm already search in the web for any example SD CARD IP Core, but 'till now it's all not free :( . Please if anyone can help me ?

    Hi quray,

    sd_controller_dev_init'sd_open_wrapper'sd_close_wrapper',etc Is it a function ?

    If it is a function please check Have you already include the .h file that describe the function ?

    I'm new in here but i'll try my best to share my experience.:)

    Than you very much.I have solved this problem.

    sopc builder in Quartus 8.1 is different from Quartus 6.1 .

    in \neek_alternate_sd_card_controller\sd_card_controller_component\SD_Card_Controller_SPI\HAL\src

    create component.mk ,and add # This file generated on 2006.03.22.10:57:43

    C_LIB_SRCS += sd_controller.c\

    fat.c\

    fat_file.c

    ASM_LIB_SRCS +=

    INCLUDE_PATH +=

    # end of file

    in this file.
