nios2 / terminal

Hi,

Do you have experience with nios2 and a specific terminal (hyperterminal,
tera pro, or others) ?.
I have problem to only have an easy printf message !!....

I 'm using Stratix(10) Altera Develop KIT with UART "console" DB9.
I'm using example 'standart' (this example have an uart)
In the Nios software I'm using example 'hello_word".

jtag_uart is OK,  I receive this message 'hello_word' in the NIOS IDE
console.

How could I obtain this result with "uart" and a terminal.
How can I do choices ('jtag_uart' and/or 'uart') to write this message ('IDE
console' and/or 'terminal') ?.
(for example options in properties of system library => std_out, std_err,
std_in)

When I'm trying this example with UART, I have two result :

=> if I don't connect first the COM of the terminal:
         nios2-terminal: connected to hardware target using UART on
/dev/com1 at 115200 baud
         nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)
=> if I connect first the COM of the terminal :
          nios2-terminal: can't open uart: Permission denied
(So I'm using COM2 as terminal, and I connect the cable to this COM2, and I
configure the properties of system library as COM1.  )

(no hardware problem with RS232 c�ble, loopback test is OK with pin 2 and 3
of DB9).

Regards,

H.

check also niosforum.com

normal printf goes to stdout, this depends on the settings
in system library properties (stdout).
if a special device should be used then use
fopen("device_name") and fprintf(filepointer,...)
in your debug settings ( use Run-> debug... ) tab "Target connection",
"NiosII Terminal Communication device" and set it to the device the 
integrated terminal should use.
e.g. set it to none if you want to use hyperterminal.
