Executing the Reference System

Executing the Reference System

Provided with this Reference System

A µClinux-ready MicroBlaze system and µClinux kernel are provided in this reference
system. This basic µClinux implementation is built using the µClinux version 2.4.32
distribution.
The µClinux kernel image is stored in the Intel StrataFlash PROM and is available in
/uClinux_images under the project root directory.
Note:
Executing the µClinux Reference System
To execute the µClinux reference system, the hardware bitstream and the µClinux kernel
image must be downloaded into main memory (DDR) by:
1.
2.

Generating the Bitstream

The system netlist and bitstream can be generated by:
1.
2.

Downloading the Bitstream

To configure the Spartan-3E device, the bitstream can be downloaded by using one of two
methods:
1.
2.
The bitstream can be found under the project root directory as
/ready_for_download/download.bit.
Downloading the µClinux Kernel
Before the µClinux demonstration can be executed, a serial communications utility, such as
HyperTerminal, must be set up. To configure the HyperTerminal and run the µClinux
demonstration on MicroBlaze, the following steps are followed:
1.
14
The method and details for building a µClinux kernel are beyond the scope of this document.
Downloading the bitstream directly from the /ready_for_download directory or
by generating it from the project in XPS. The bitstream is composed of the hardware
configuration and a simple bootloop software application, which loops the MicroBlaze
processor at a known location until another application is executed.
Downloading the µClinux kernel image from the directory /uClinux_images under
the project root directory.
Opening the µClinux project in XPS, then
Generating the bitstream by selecting Hardware → Generate Bitstream in XPS
Using the download option in XPS, then connecting the USB cable from the PC to the
board and selecting the Device Configuration → Download Bitstream option
Using the iMPACT configuration tool and downloading the bitstream.
A serial cable from the COM port of the PC to the DTE serial port on the board is
connected.
