Hello World not working in NIOS II

I have a Altera EP2C8Q208C8 FPGA and 256MB SDRAM ,50MHz Oscillator, EPC4S Hardware , in order to test the hardware Hello world in NIOS II is being tested. In Quartus 10.1, cpu , SDRAM , JTAG UART , epcs controller ansd some PIO are used. Auto assign base address and Auto assign IRQ are done, SOPC are built successfully . All IC pin connection are done by Pin Planner , and the Quartus are compiled successfully. In Nios II IDE workspace are chosen in project directory and Hello world are selected , under project name system library , stdout and others are selected jtag_uart , Program memory(text) , read only data memory and others SDRAM are used. Under project name right click mouse and select run as NIOS II hardware and let the program runs. In Console the following words are seen but without the words "Hello from Nios II!".
