Hello World project without return message

[Altera_Forum]

Hello, 

I built a SOPC with NIOS II/f, on-chip RAM, pll, and sysid. NIOS II/f operates at 100MHz. And when I trying to run hello world as NIOS II Hardware, the following messages show in the console window: Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Pausing target processor: OK Reading System ID at address 0x00081020: verified Initializing CPU cache (if present) OK Downloading 00040000 ( 0%) Downloaded 42KB in 0.7s (60.0KB/s) Verifying 00040000 ( 0%) Verified OK  Leaving target processor paused   the "Hello from Nios II!" is not appeared. Is it normal? What should I do to fix this problem? Thanks for every trying to help me!   PS. No error or warning occurs in building & runing the hello world project

Do you have a jtag uart and is it defined as standard output?

How to define the jtag uart as a standard output? 

I've include a jtag uart in my system.

Dear Daixiwen: 

I also check the jtag_uart_input_stream.dat and output_stream.dat There are only 00000000 in input_stream.dat and nothing in output_stream.dat  Thanks for reply!

And modify the system.h based on the corresponding parameter. And pass compilation, runing well.But still no "Hello XXXX" in console window.

If you have any idea, please tell me! 

Thanks again everyone!

The problem is fixed now!

[Altera_Forum]

How did you fix it?

[Altera_Forum]

Just rename the jtag_uart_0 to jtag_uart and rebuild the system. 

Set N2 terminal communication device. After these steps, the hello world fully works. Sorry for wasting your time in this stupid bug.

It isn't time wasted, civing the solution could help others that have the same problem. 

I find it strange though, from the system.h extract that you gave, it seems that the tools identified correctly the name of your uart... Anyway I'm glad it is working now!
