Adding an SD card to the RCM6700

You could use:

Our customers will probably also want FAT file system support for the custom SD card. In FAT_CONFIG.LIB, the RCM6700 entries and definitions should be modified, once again following the RCM4300's example for the SD card. It is also possible, but more complicated, to set up the SD card as a secondary FAT device while leaving the on-core serial flash as the primary FAT device. The best example for this dual-device FAT file system support is actually in Dynamic C 9.62, where that version's FAT_CONFIG.LIB's RCM3900 conditional section demonstrates how to set up two different FAT interface drivers with two different devices, the second device being an SD card.
