User Guide
After your design files are in the .flash format, use one of the following to write the
.flash
files to the user software locations of the flash memory:
■ Board Update Portal. Refer to “Using the Board Update Portal to Write User
Designs” on page 5–2 for more information.
■ Nios II EDS nios2-flash-programmer utility.
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 .srec file to the board using
nios2-flash-programmer
, do the following:
1. Set the SW4.3 DIP switch to the FACT ON (logic 0) 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 Config Done LED (D7) does not illuminate, continue to step 4 to load
the FPGA with a flash-writing design.
4. Run the Quartus II Programmer to configure the FPGA with a .sof capable of flash
programming. Refer to “Restoring the MAX V CPLD to the Factory Settings” on
page 4–5 for more information.
5. Click Add File and select
dir>\kits\cycloneVGT_5cgtfd9ef35_fpga\factory_recovery\c5gt_fpga_bup.sof.
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 Config Done LED (D7)
illuminates 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
dir>\kits\cycloneVGT_5cgtfd9ef35_fpga\factory_recovery directory.
You can also navigate to the directory of the .flash files you created in “Creating
Flash Files Using the Nios II EDS” on page A–2 )
10. Type the following Nios II EDS command:
nios2-flash-programmer --base=0x00000000 _hw.flash
r
11. After programming completes, if you have a software file to program, type the
following Nios II EDS command:
nios2-flash-programmer --base=0x00000000 _sw.flash
r
12. Set the SW4.3 DIP switch to the FACT OFF (logic 1) position and power cycle the
board.
Programming the board is now complete.
