after some time and headache here is some results. It's just amazing what IAR can do, atollic is just waste of time, same code compiled with IAR runs lot faster than compiled with atollic. Get 50MHz IO toggle so far, and with atollic can get around 3MHz (PLL and clock settings are the same)

Good luck with the FAT file system, it's a pain in the :-x, especially if you want long file name support.
You can make life easier by only implementing a subset of the functionality. 8.3 filenames and no subdirectories would be a good starting point.
FTDI make a device called the Vinculum. Among its many uses, it converts USB thumb drives to SPI or RS232, and has a FAT file system driver embedded in it.
