Working with pre-flashed software

SPEAr evaluation boards come with default embedded Linux software already stored in

(serial NOR) Flash memory, according to a pre-defined generic configuration. Using a

SPEAr board with pre-flashed software is initially useful to get familiar with the target

hardware platform and the embedded Linux environment.

This activity does not strictly require the installation of the SPEAr Linux support package

(software development environment). This can be performed later as, described in

Chapter 3 of this document.

Before powering-on target hardware, hence booting the pre-flashed software, please

carefully check the specific hardware configuration (for example, DIP switches) according to

what is described in the relevant hardware manuals.

Host PC requirements

2.1.1

Windows PC

In order to control the target hardware, use a PC with a Microsoft Windows operating

system (XP, Vista, Windows 7).

The first step is to set up a serial port for interacting with the embedded consoles (Linux

shell or U-Boot boot loader). If a RS232 serial port is not available on the PC, you can use a

USB/RS232 adapter (not provided in the kit).

The second step is to obtain a terminal emulation program. Windows comes with the built-in

HyperTerminal, but any equivalent tool can be used as an alternative. For instance, Tera

Term is an open source free application with more features and higher flexibility, especially

its scripting capability.

You can download and find more technical information about Tera Term on:

http://en.wikipedia.org/wiki/Tera_Term

In order to configure the serial port with TeraTerm;

Launch the tool

Click on "Setup > serial port"

The configuration must reflect that shown in Figure 2.

To save the proper setting, click on "Setup > save setup".
