Need Help For Learning Sd Card Ip Core

[Altera_Forum]

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.  http://www.cnblogs.com/oomusou/archive/200...mponent_mk.html (http://www.cnblogs.com/oomusou/archive/2008/12/06/ip_component_mk.html)
