Rs232 Uart Nios

Hello,

I am trying to get hyperterminal or Putty to show either the boot messages or the stdout of my NIOS II program. I have tried configuring my HAL to output stdout to uart_0 (instead of jtag_uart) and I have tried configuring the log messages to come out of uart_0 but nothing seems to be showing up on the terminal.

I have pinned everything out correctly on my fpga side and made sure to have matching baud rates, etc.

I am trying to output a simple "hello world" out of the uart or at least see the boot messages show up so I know some real connection is there between my NIOS II inside the fpga and my physical RS-232 serial port. Obviously I instantiated a UART via sopc, etc.

Any help?

    in the IDE project properties make sure you select UART for stout

    You mean in the BSP Editor where you configure the HAL right? Because I already did that. Still nothing...no evidence that anything is actually going through to the serial port.

    Any other clues?

    It's as if my serial port is not connected - which it is. But it would be the same effect if it were not.
