Build OpenFat

Get a copy of the openfat source from here

Steps:

tar -zxf tmolteno_openfat_xxx.tar.gz
cd openfat_xxxx
make HOST=stm32
cd stm32
make

Testing Openfat

To test, you need a Fat32 image. To do this,

cd unix
sudo make fat32.img
sudo mount fat32.img /media/test
sudo cp Makefile /media/test
sudo umount /media/test

The last line copies a file onto the fat32 filesystem.
