● alt_sys_init.c: an initialization file that initializes the devices in the system.● Hello_world_0.elf: an executable and linked format file for the application located inhello_world_0 folder under the Debug directory.7.5 Build and Run the ProgramIn this section you will build and run the program.To build the program, right-click the hello_world_0 project in the Nios II C/C++ Projects tab andselect Build Project. The Build Project dialog box appears and the IDE begins compiling theproject. When compilation completes, a message ‘Build complete’ will appear in the Console tab, asshown in Figure 7-57.Figure 7-57 Nios II IDE hello_world_0 Build CompletedNote: If there appears in the console tab, an error, “region onchip_memory2 isfull(hello_world_0.elf section .text). Region needs to be XXX bytes larger.” , please right-clickhello_world_0 , select System Library Properties menu, then pop a window. In the System LibraryProperties window, select Small C Library, then click OK to close the window. Rebuild the project.122
After a successful compilation, right-click the hello_world_0 project, select Run As > NIOS IIHardware. The IDE will download the program to the target FPGA development board and beginexecution. When the target hardware begins executing the program, the message ’Hello from NiosII!’ will appear in the NIOS II IDE Console tab, as shown in Figure 7-58 for an example.Figure 7-58 Hello_World_0 Program OutputNow you have created, compiled, and run your first software program based on NIOS II. And youcan perform additional operations such as configuring the system properties, editing and re-buildingthe application, and debugging the source code.7.6 Edit and Re-Run the ProgramYou can modify the hello_world.c program file in the IDE, build it, and re-run the program toobserve your changes, as it executes on the target board. In this section you will add code that willmake the green LEDs, on the DE0-Nano board, blink.Perform the following steps to modify and re-run the program:1. In the hello_world.c file, add the text shown in blue in the example below:#include 123
