4. Click OK. The BSP regenerates, the Properties dialog box closes, and you return to
the Nios II SBT for Eclipse.
5. In the Project Explorer view, right-click the count_binary project and click Build
Project.
The Build Project dialog box appears, and the Nios II SBT for Eclipse begins
compiling the project. When compilation completes, a "count_binary build complete"
message appears in the Console view.
Run the Program on Target Hardware
In this section you download the program to target hardware and run it. To download
the software executable to the target board, perform the following steps:
1. Right-click the count_binary project, point to Run As, and then click Nios II
Hardware. The Nios II SBT for Eclipse downloads the program to the FPGA on the
target board and the program starts running.
1 If the Run Configurations dialog box appears, verify that Project name and
ELF file name contain relevant data, then click Run.
When the target hardware starts running the program, the Nios II Console view
displays character I/O output. Figure 1–22 shows the output. If you connected
LEDs to the Nios II system in “Integrate the Qsys System into the Quartus II
Project” on page 1–24, then the LEDs blink in a binary counting pattern.
2. Click the Terminate icon (the red square) on the toolbar of the Nios II Console
view to terminate the run session. When you click the Terminate icon, the Nios II
SBT for Eclipse disconnects from the target hardware.
You can edit the count_binary.c program in the Nios II SBT for Eclipse text editor and
repeat these two steps to witness your changes executing on the target board. If you
rerun the program, buffered characters from the previous run session might display in
the Console view before the program begins executing.
f For information on running and debugging programs on target hardware, refer to the
tutorial in the Getting Started with the Graphical User Interface chapter of the Nios II
Software Developer’s Handbook.
