Configure the Stratix II Device Directly
You can configure the Stratix II device directly, without turning off power,
using the Quartus
® II software and the USB Blaster cable, as follows.
1. Attach the cable to J21, also labeled “JTAG Stratix II”.
2. Open a Quartus II SRAM Object File (.sof), which starts the
Quartus II Programmer.
3. Select USB Blaster as the hardware.
4. Set the mode to JTAG.
5. Click Start.
After successful configuration, the CONF_DONE LED (LED5)
illuminates.
f
Refer to Quartus II Help for instructions on how to use the USB Blaster
cable.
Nonvolatile
Configuration The designer must reconfigure the Stratix II device each time power is
applied to the Stratix II DSP development board. For designers who want
to power up the board and have a design immediately present in the
Stratix II device, the board has a nonvolatile configuration scheme. This
scheme consists of flash memory and a configuration controller (U10),
which is an Altera EPM7256 PLD. The configuration controller device is
non-volatile (i.e., it does not lose its configuration data when the board is
powered down) and it comes factory-programmed with logic that
configures the Stratix II EP2S180F1020C3 device (U18) from data stored in
flash (U17) on power-up. Upon power-up, the configuration controller
begins reading data from the flash memory. The flash memory, Stratix II
device, and configuration controller are connected so that data from the
flash configures the Stratix II device in fast passive-parallel mode.
Factory & User Configurations
The configuration controller can manage two separate Stratix II device
configurations stored in flash memory: one user design and a factory
design. On power-up, the configuration controller reads one of two (user
or factory) designs from the flash memory and programs the Stratix II
device accordingly. The user can select with which design the Stratix II
device is programmed by setting the DIP switches on SW2.
