Non-Volatile Configuration  
1
Intel-format HEXOUT files contain data that is not actually  
written to the flash memory. The Write2Flash executable file  
(provided in the <installation directory>/utilities/  
Flash_Programmer directory) parses the HEXOUT file and  
creates a file with the extension .hexout.flash that contains the  
data to be written to flash memory. The designer can then send  
this file serially to the board via an RS-232 cable and write it to  
flash memory by the factory configuration as described in the  
next section.  
Factory & User Configurations  
The configuration controller can manage four separate Stratix II device  
configurations as HEXOUT data stored in flash memory: three user  
designs and a factory design. On power-up, the configuration controller  
reads one of the four (user or factory) designs from the flash memory and  
programs the Stratix II device accordingly. The user can select which  
design the Stratix II device is programmed with by setting the DIP  
switches on SW2.  
DIP switches 1 through 3 on SW2 select one of four possible Stratix II  
configuration images upon power-up. When DIP switch 4 is in the  
“OPEN” position the configuration controller is enabled. If DIP switch 4  
is in the “OPEN” position and there are no valid user-defined images, the  
Stratix II device is programmed with the factory configuration. Table 2  
shows the DIP switch combinations used to select the available images.  
See “Non-Volatile Configuration” on page 7 for more details.

An alternative method of configuring the device with the  
factory design is to press push-button switch SW3.
