Hardware problem of Compact Flash Card.

Hello,

I made a CF card used in my Mtx.Cyclone.Board. It connects with the short Santa Cruz Connector. I use the Proto_IO[0:41], PROTO_SELn and PROTO_RSTn in the short Santa Cruz Conn.

I made this card followed the Compact Flash Socket Schematics in Altera 1C20 board and change some resistors value of FDC6323L-Integrated Load Switch.

Now, the card can not work(Before I use the card, I test the power first. It seems OK. Then, I use fopen, but can not open CF card). I do not know what the problem is and how to deal with my card. I think it is the hardware problem, but I do not know how to test the hardware.

If can paste schematics of my CF card, I will do. (I do not know how to paste my schematics(pdf file or image file)).

Someone can help me to test my Compact Flash Card.

Or, if someone has nios reference schematics of compactflash, can mail me one?

Thank you very much.
