A simple example on how to use the UART interface on xmc2go using DAVE4 (NO DAVE APPS) for xmc2go by Infineon. Main.c was taken from here The rest of the files was generated using DAVE4 (simple main template).
Import with project wizard, compile, connect xmc2go and debug. Open putty on respective serial COM port with 115200 8 N. Press 'A' to toggle with of the red LED's on the board.
Minimal working example without all the crap.
