Using the Board Update Portal to Update User Designs

Stratix IV GT 100G Development Kit User Guide October 2010 Altera Corporation

f You can also navigate directly to the Stratix IV GT 100G Development Kit page of the

Altera website to determine if you have the latest kit software.

Using the Board Update Portal to Update User Designs

The Board Update Portal allows you to write new designs to the user hardware

portion of flash memory. Designs must be in the Nios II Flash Programmer File

(.flash) format.

1 Design files available from the Stratix IV GT 100G Development Kit page of the Altera

website include .flash files. You can also create .flash files from your own custom

design. Refer to “Preparing Design Files for Flash Programming” on page A–2 for

information about preparing your own design for upload.

To upload a design over the network into the user portion of flash memory on your

board, perform the following steps:

1. Perform the steps in “Connecting to the Board Update Portal Web Page” to access

the Board Update Portal web page.

2. In the Hardware File Name field specify the .flash file that you either downloaded

from the Altera website or created on your own. If there is a software component

to the design, specify it in the same manner using the Software File Name field,

otherwise leave the Software File Name field blank.

3. Click Upload.

4. To configure the FPGA with the new design after the flash memory upload process

is complete, press PGM_SEL (S10) until the POF 1 LED illuminates, and then press

LOAD (S11) to configure the user hardware portion of flash memory.

1 As long as you don’t overwrite the factory image in the flash memory device, you can

continue to use the Board Update Portal to write new designs to the user hardware

portion of flash memory. If you do overwrite the factory image, you can restore it by

following the instructions in “Restoring the Flash Device to the Factory Settings” on

page A–4.
