Chapter 5: Creating the Software Application 5–7

Run the Software Application on the NEEK

Preliminary

Run the Software Application on the NEEK

Running an application on the target hardware requires the following two image files:

■ FPGA hardware image SRAM Object File (.sof)

■ Software executable image (.elf)

In Chapter 4, Completing the Quartus II Project, you configured the FPGA by

downloading the .sof to the FPGA. After you configure the FPGA, it is ready to run

the software application. You download the application through the USB cable that

remains plugged in to the NEEK board.

To run the software project on the Nios II processor you configured on the NEEK,

perform the following steps:

1. Right-click neek_picture_viewer.

2. Click Run As > Nios II Hardware.

3. If the message You have more than one JTAG cable available appears in the

Nios II IDE Console window, perform the following steps:

a. On the Run menu, click Run.

b. On the Target Connection tab, for JTAG cable, click USB-Blaster.

c. Click the Run button.

The Run or Run As command rebuilds the software project to create an up–to-date

executable and then download the code to memory. The debugger resets the Nios II

processor, and the Nios II processor then executes the downloaded code.

Console Output

After the application begins executing, it relays messages to the Nios II IDE through

the JTAG interface. Figure 5–7 shows the output in the Nios II IDE Console window.
