Flash Memory (U17)
U17 is a 16-Mbyte flash memory device connected to the Stratix II device.
It can be used for two purposes:
■
A Nios II embedded processor implemented in the Stratix II device
can use the flash as general-purpose readable memory and
non-volatile storage.
■
The flash memory can hold a Stratix II device configuration file that
is used by the configuration controller to load the Stratix II device at
power-up.
Refer to
Table 19
for Stratix II pin-outs for flash memory device U17.
Hardware configuration data that implements the sines reference design
is prestored in this flash memory and configures the Stratix II device with
this design on boot up. A Nios II reference design can identify the 16-
Mbyte flash memory in its address space, and can program new data
(either new Stratix II configuration data, Nios II embedded processor
software, or both) into flash memory. The Nios II integrated development
environment (IDE) provides a Flash Programmer feature, which you can
use to program flash memory. Altera also provides Nios II routines for
writing and erasing flash memory. To program or erase flash memory,
you need to install the Nios II development tools from the Nios II
Embedded Processor Windows, version 6.0 CD-ROM included in your kit,
and use the Nios II IDE Flash Programmer. To use the Flash Programmer
with the DSP board, you must specify an SOPC Builder setting that
locates a board description file for the DSP board. Perform the following:
1.
Start the Quartus II software.
a.
Choose Tools > SOPC Builder... to start SOPC Builder from the
Quartus II software.
b.
In SOPC Builder choose File > SOPC Builder Setup
c.
In the Componet/Kit Library Search Path enter the path to the
Stratix II DSP board component. Use "+" to delineate multiple
paths. Specify the following path:
C:\altera\kits\StratixII_DSP_Kit-v6.0.1\Examples\<board
name>\NiosII
