There is sample code in the Xilinx ML40x reference designs, under
software applications. In particular, there is an example program for
MicroBlaze that shows how to read and write files from the DOS partition
on the compact flash card. I don't think you have to worry about
partitions and all that, it's handled by some Xilinx FAT filesystem code.
