Nios II runs Hello world by chance

[Altera_Forum]

I have EP2C8Q208C8 with 64M SDRAM running NIOS II ( 11.0 SP1 ) Hello World example with Signal Tap II, console output word " Hello World " by chance , only have these words below 

 nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)   without output the word " Hello world " I know that NIOS CPU is not working ( no data output from Signal Tap II ) , can someone help me how to solve this problem ??

The words above are printed by the nios2-terminal host application when it starts up - they do not come from the nios2 processor. 

 I would start by checking that your clock is running, that your reset drives at the correct time and is not stuck asserted and that you are getting no critical warnings from the timing analyser.  Once you've done that check the output from `jtagconfig -n` contains a Nios II processor and check what nios2-download says about it.
