Abstract This application note describes the files for programming the serial Flash memory and the
StrataFlash memory for the MicroBlaze™ Development Kit - Spartan
®
-3A DSP 1800A Starter
Platform. The reference system is created to execute the HelloWorld software application to run
from the Serial Flash using SPI configuration mode and the BlueCat Linux image from the
StrataFlash in BPI configuration mode. All files needed to run the BlueCat Linux reference
system from the StrataFlash memory and the HelloWorld application from the Serial Flash are
provided for the user with the Development Kit. This application note describes how to use the
provided files, as well as create new files, to run the reference system successfully from the
Flash memories.
Introduction The SP3ADSP1800A board supports a variety of FPGA configuration options. One of the
options is to program the on-board Intel StrataFlash parallel NOR Flash PROM, then configure
the FPGA from the image stored in the Flash PROM using the BPI configuration mode. The
other option is to program the on-board Serial Flash, then configure the FPGA from the image
stored in the Serial Flash PROM using the SPI configuration mode.
Hardware and
Software
Requirements
The hardware and software requirements are:
• Xilinx Spartan-3A DSP 1800A Starter Platform
• Xilinx Parallel Cable IV (PC4) or Platform Cable USB with flyleads
• RS232 serial cable and serial communications utility, such as HyperTerminal
• Xilinx Platform Studio 10.1.3
• Xilinx Integrated Software Environment (ISE®) 10.1.3
Configuration
Using the Intel
StrataFlash
To boot the BlueCat Linux image from parallel Flash, the Linux image, the root file system, and
a bootloader application must be programmed into Flash. The bootloader application copies
the Linux image from Flash to DDR2 memory and boots BlueCat Linux.
The files required to run the BlueCat Linux demonstration out of the StrataFlash memory are
provided with the Development Kit, and are documented by UG486
.
The steps for programming the BlueCat Linux image into parallel Flash are detailed in the
subsequent sections.
After programming all the files into the Flash memory as directed, the Flash memory will have
the address map shown in Table 1. The files do not neccessarily take the entire space
assigned. Each file starts on a block boundary so that each can be erased individually without
affecting the other files in the device.
