19 years agoHi Karis,
We also had to implement FAT file system on our own-design board without OS. I found two very useful papers on the subject, one by Jack Dobiash and another by Microsoft - fatgen102.pdf. Both are easy to find on google. In fact, with both documents there is everything you need to know to write a FAT file system (apart form details of long file names). These may help you understand the example project. If your project only needs to read and/or write CF cards then you need only write those functions. Use a CF card read/writer on a PC to format and manage the cards. CF cards now have high capacity for relatively little cost so it makes sense to only support FAT32 (on 64Mb+ cards). Good luck. Banx.
