Hi, I am working with uVision2 V2.40a and i am writing an application for MC C515C-L of Infineon. While using the simulator, the program works exactly as it should. When debugging the programm directly on the Hardware, the program stops running when using printf. Whenever printf is called, the programm remains waiting for an interrupt signal which is never receveid. Has any body had the same problem ? best regards Hammoud
