Sorry, I meant MMC Card, not SD Card.

By mfr link, I mean: where exactly did you buy this board? What is the vendor's website? If you didn't buy it, what more do you know about it other than "cobra5329 based on MCF5329 coldfire processor"? A quick googling turned up senTek and domologic, e.g.

What I am hoping is that somewhere on the vendor website is support information detailing exactly the state of MMC Card support. You can do this yourself, of course (and I expect you should have before posting here). I am merely trying to lend a hand.
