If you have generated a .sof that operates without a software design file, you can still
use the Board Update Portal to upload your design. In this case, leave the Software
File Name field blank.
Programming Flash Memory Using the Nios II EDS
The Nios II EDS offers a nios2-flash-programmer utility to program the flash memory
directly. To program the .flash files or any compatible S-Record File ( .srec ) to the
board using nios2-flash-programmer , perform the following steps:
1. Set the USER_PGM switch (S8.2) to the off position to load the Board Update
Portal design from flash memory on power up.
2. Attach the USB-Blaster cable and power up the board.
3. If the board has powered up and the LCD displays either "Connecting..." or a valid
IP address (such as 152.198.231.75), proceed to step 8. If no output appears on the
LCD or if the CONF DONE LED (D2) does not illuminate, continue to step 4 to
load the FPGA with a flash-writing design.
4. Launch the Quartus II Programmer to configure the FPGA with a .sof capable of
5. Click Add File and select <install
dir> \kits\cycloneIVGX_4cgx15_starter\factory_recovery\c4gx15_starter_bup.s
of .
6. Turn on the Program/Configure option for the added file.
7. Click Start to download the selected configuration file to the FPGA. Configuration
is complete when the progress bar reaches 100%. The CONF DONE LED (D2) and
the four user LEDs (D5-D8) illuminate indicating that the flash device is ready for
programming.
8. On the Windows Start menu, click All Programs > Altera > Nios II EDS > Nios II
Command Shell .
9. In the Nios II command shell, navigate to the <install
dir> \kits\cycloneIVGX_4cgx15_starter\factory_recovery directory (or to the
nios2-flash-programmer --base=0x08000000 <yourfile> _hw.flash r
10. After programming completes, if you have a software file to program, type the
following Nios II EDS command:
nios2-flash-programmer --base=0x08000000 <yourfile> _sw.flash r
11. Set the USER_PGM switch (S8.2) to the on position and power cycle the board, or
press the PGM_SEL button (S2) until the PGM 0 LED (D4) is on and the PGM 1
LED (D3) is off and then press the PGM_CONF button (S1) to load and run the
user hardware 1 design.
Programming the board is now complete.
