I ported the FATfs to a CW project on a STM3210E-EVAL bd. The interface is SDIO. The real-time clock stuff is untested, but we will be implementing a full clock-calender and I will post again then. The project is attached. The main code formats the card then creates and writes a file. Also displays some card info. If you do not comment out the format code block your card will get formatted.
