5.2.6 microSD™ Card Drivers
The Dynamic C
Card memory devices on an SPI bus. More information on these function calls is available
in the Dynamic C Function Reference Manual.
Application developers are cautioned against modifying the BIOS code to insert application-
specific external I/O (IOE) instructions before the GOCR register and its shadow are initial-
ized by the standard BIOS code. Such IOE code will cause the microSD™ Card select to
toggle, possibly interfering with the microSD™ Card operation.
The microSD™ Card is ideally suited to store files with a directory structure. The Dynamic
C FAT file system included with Dynamic C provides support for a file system and for for-
matting the microSD™ Card for use in a Rabbit-based system. This allows files to be read
and written in a PC-compatible manner. The supporting documentation for the Dynamic C
FAT File System and the sample programs in the
illustrate the use of the Dynamic C FAT file system.
RabbitCore RCM3900 User’s Manual
NOTE: Dynamic C has a utility for partitioning storage devices. Rabbit recommends that
you do not partition the microSD™ Card since doing so would make it not PC-compati-
ble.
