DE2 Board : Using SD Card without NIOS II

Hello, I'm Korean Student studying VHDL.

Sorry for my english....

I'm making Drum loop machine for my term project.

It loads wav files as drum beat from sd card then play it.

I don't know about nios II,

so I want to use SD Card without nios II.

But I can't find any appropriate example or solutions....

May I borrow your hand???

    Reading a file from a file system is typically something that is way easier to do in software than in hardware. I'm not aware of any project that can read a file without using a CPU.

    You need to read SD_CARD registers

    There are many registers associated with SD_CARD with different addresses

    It is much more efficient to read SD_CARD by using a CPU like Nios II
