It might be better to change the function so that each call toggles
the LED rather than turn it off and on.

What do you mean by going to the main function? Which function is
that? In some configurations you might end up with a dummy main()
thread which will just exit, it won't have any effect on your program.

Can you still get this program running as it was originally intended,
with just the printf()s? If so, what then happens if you then add the
led functions? Try to work out what differs between the working
version and the non-working version.
