16.16 Downloading the Nios II Hardware and Software
Projects
To execute your software on a Nios II processor, you must configure the FPGA
with the Nios II hardware reference design and then you can download the
compiled program code to the processor's program memory.
Connect the USB cable. Verify that the
Run/Prog
switch on the DE board is set
to
Run
, and then turn on the DE board. Select
Tools
Quartus II
Programmer…
to configure the FPGA. When the
Quartus II Programmer
appears, click on
Add File…
and select the
rpds16.sof
file from your project
directory. Click
Open
to add the selected file to the download chain. Check the
