Makefile not up to date.
C:/Users/Administrator/Desktop/NIOS/NOIS_cpu.sopcinfo has been modified since the BSP was generated.
Generate the BSP to update the Makefile, and then build again.
To generate from Eclipse:
1. Right-click the BSP project.
2. In the Nios II Menu, click Generate BSP.
To generate from the command line:
nios2-bsp-generate-files --settings=<settings file> --bsp-dir=<target bsp files directory>
