1.4.3.1. Regenerating and Downloading ELF File

By default, the ELF file is generated when you generate the dynamic design example.
Note: You need to regenerate the ELF file if you modify a software file such as the main.c or config.h files or when you modify and regenerate the dp_core.qsys file. Regenerating the dp_core.qsys file updates the .sopcinfo file, which requires you to regenerate the ELF file.
  1. Go to <project directory>/software and edit the code if necessary.
  2. Go to <project directory>/script and execute the following build script:
    source build_sw.sh.
    • On Windows, search and open Nios® II Command Shell. In the Nios® II Command Shell, go to <project directory>/script and execute source build_sw.sh.
    • On Linux, launch the Platform Designer, and open Tools > Nios® II Command Shell. In the Nios® II Command Shell, go to <project directory>/script and execute source build_sw.sh.
  3. Make sure an .elf file is generated in <project directory>/software/dp_demo.
  4. Download the generated .elf file into the FPGA without recompiling the .sof file by running the following script:
    nios2-download <project directory>/software/dp_demo/*.elf
  5. Push the reset button on the FPGA board for the new software to take effect.
