If you have a HPC (PIC18F8722) with the SD/MMC PICTail then I can send you an image you can test.

Dear asmallri,

I don't have the standard SD/MMC pigtail as I have designed my own circuit board ...

You might want to check out my file system driver. It concurrently supports FAT12, FAT16 and FAT32. FAT16 and FAT32 have been extensively tested. I generally recommend FAT16 for the PIC because it r ...

I just see the CCS code defaults to FAT32 but I remember reading somewhere the FAT16 is more stable. In FAT.c change to FAT16: /// Define your FAT type here ///
//#define FAT16

Dear crystal_lattice,

I think the return carriage character is well understood as it is the only character that isn't echoed back (as specified in the code.. so it is recognized).
