Running make
nios2-bsp places all BSP files in the BSP directory, specified on the command line with argument --bsp-
dir. After running nios2-bsp, you run make, which compiles the source code. The result of compilation
is the BSP library file, also in the BSP directory. The BSP is ready to be linked with your application.
You can specify multiple targets on a make command line. For example, the following command removes
existing object files in the current project directory, builds the project, downloads the project to a board,
and runs it:
make clean download-elfr
You can modify an application or user library makefile with the nios2-lib-update-makefile and nios2-
app-update-makefile utilities. With these utilities, you can execute the following tasks:
• Add source files to a project
• Remove source files from a project
• Add compiler options to a project’s make rules
• Modify or remove compiler options in a project’s make rules
Creating Memory Initialization Files
To create memory initialization files for a Nios II system, you can use the Nios II Command Shell. Change
to the software application folder, and type:
make mem_init_generater
This command creates the memory initialization and simulation files for all memory devices. It also
generates a Quartus II IP File (.qip). The .qip file tells the Quartus II software where to find the initializa‐
tion files. Add the .qip file to your Quartus II project.
