Tool: Nios® II SBT


In the Nios II SBT that comes with Quartus® II v14.1 or earlier, it can be specified at compile time by right-clicking on the application project (without _bsp) ⇒ Properties ⇒ Nios II Application Properties User Flag cannot be set.
A workaround is to edit the Makefile directly.
Open the Makefile in the Nios II SBT application project (without _bsp) and add the flags you want to specify to the following lines.

(Before editing)
APP_CFLAGS_USER_FLAGS :=

(after editing)
APP_CFLAGS_USER_FLAGS := -mcustom-fwrx=0 -mcustom-fwry=1 -mcustom-frdxlo=2

If you save the Makefile, you can see that the Nios II Application Properties are set to the values you specified.
