Working with the Nios II Development Environment

• The application itself, including implementations of the event handler

functions and callback handler functions of the FTXL LonTalk API.

• The FTXL non-volatile data driver. You can modify the driver from the

example applications.

• The FTXL operating system abstraction layer. You can modify the FTXL

OSAL from the example applications to provide support for an operating
system other than the Micrium μC/OS-II operating system or to change

the settings for the operating system.

• The FTXL hardware abstraction layer. If your FTXL device’s hardware

differs from the design recommendations in the

FTXL Hardware Guide

you might need to modify the FTXL HAL. To debug the FTXL HAL, you
should run the FTXL Bring-Up application, which is described in the

FTXL Hardware Guide

To debug the application from the Nios II IDE:

1. Ensure that the FPGA device board is powered on and that a device

programmer (such as a USB-Blaster download cable) is connected to the

board’s JTAG header connector.

2. Start the Nios II IDE.
3. Right-click the FTXL application project from the Nios II C/C++ Projects

pane and select Debug As → Nios II Hardware. The Nios II IDE
recompiles the project, and opens the Debug perspective.

4. If you have a valid Nios II development license, and have already loaded

the configuration data (the JTAG Indirect Configuration (*.jic) file or

SRAM object file (*.sof)) into the FPGA device, proceed to step 6.

5. If you do not have a valid Nios II development license, or have not loaded

the configuration data into the FPGA device, follow the procedure listed

on page

6. The Nios II IDE halts the application at the first executable statement.

You can step into the code, step over functions, or run the application to a
breakpoint.

To verify that the application runs as expected, connect the FTXL device to a

ORKS

network, and commission it using a network management tool, such

as the LonMaker Integration tool.
