Your message doesn't tell in which environment. Are you using
arm-wince-cegcc or arm-wince-mingw32ce tools ?
Also a simple test program would help things. I am attaching a simple
one which I have used a lot. It creates a file and writes about 20 lines
of text.
It could be simplified more but then I'd have to wake up before sending
this mail :-)
You may want to change the line that defines FN so it fits your PDA's
directory structure.
