Trying to use JTAG UART

Hiya

I'm trying to use the JTAG UART, and the obvious thing that needs to be done is to add

"C:\altera\72sp3\ip\sopc_builder_ip\altera_avalon_jtag_uart"

to the list of include paths.

However, it seems to be difficult to add a new include path! Everything I've tried so far hasn't worked! This would take me 5 seconds in Visual C++.

What procedure do I need to follow?

    Hello,

    I can add the line:

    # include <altera_avalon_jtag_uart.h>

    to a source file and it compiles, without having to add a search path. I assume the IDE automatically searches the correct paths for the hardware you have defined. In a different project with no JTAG UART defined in the hardware, the# include line fails to compile. Have you added a JTAG UART to your SOPC component?

    Cheers

    Ahaa......

    OK, added the JTAG UART to the system, I can now compile and run the system with the JTAG UART. The UART appears to send characters, however they don&#39;t appear on the "console" window in the IDE.

    However, if I do Run-Debug, and select "jtag_uart" under "Target Connection", I now get an error dialog saying "The NIOS II Terminal communication device &#39;jtag_uart&#39; does not exist in the current SOPC Builder system file".

    Closed and restarted the NIOS IDE, then in the debug dialog, I used "Load JDI File". That seemed to overcome the previous problem, now on the console the following appears:

    nios2-terminal: There are no JTAG UARTs available which match the --device and

    nios2-terminal: --instance options you provided.

    Hmmmm.
