Help, hello_world_small can not display

Printf is large by default so try these: small c library, turn off the clean exit, reduced drivers, and 4 file descriptors (this is all in the system library properties). Also there is a hello world small example design, I forget how big it is but you may be able to cut and paste from it. When you compile, you will be told down at the bottom of the screen how big your program is and how much room is left for the heap and stack. Keep an eye out for those numbers.
