EVALSPEAr300 - evaluation board for the SPEAr300

1 Description

The EVALSPEAr300 evaluation board for SPEAr300 is intended to be used for three main
purposes:

■ To allow you to quickly evaluate and debug software for the SPEAr300

■ Act as a learning tool to rapidly get familiar with the SPEAr300 features

■ Provide a starting point for the development of the final application board

It is equipped with most of the interfacRev 2es offered by the SPEAr300.

5.1 Unpacking

ELECTROSTATIC WARNING:
The EVALSPEAr300 Evaluation board is shipped in protective anti-static packaging.
The board must not be subjected to high electrostatic potentials. General practices
for working with static sensitive devices should be applied when working with this
board.

● Wear an anti-static wristband - Wearing a simple anti-static wristband can help to

prevent ESD from damaging the Spear300 evaluation board.

● Self-grounding - Touch a grounded conducting material before handling and

periodically while handling the Spear300 evaluation board.

● Use an anti-static pad - When configuring the Spear300 evaluation board, place it on

an antic-static pad to reduce the possibility of ESD damage.

● Only handle the board edges - When handling the Spear300 evaluation board.

5.2 Connection

● Connect a serial cable (RS232 on J4) to a host PC (see Figure 4).

● On a host PC running Windows or Linux, start the Terminal program.

● Connect the AC Adapter to a power outlet.

● Power ON the board (plug the jack of the AC/Adapter on J11). A sequence of boot

messages is displayed, followed by the Linux console prompt.

For more information, refer to the SPEAr300 evaluation board software getting started user
manual available on www.st.com/spear.

5.3 Booting procedure

The SPEAr300 Board is able to boot a Linux kernel pre-installed in the serial NOR Flash.

At power on, the serial port outputs a brief header message with some uBoot information
(uBoot version, SDK version, and some internal hardware information). At this point you can
choose to:

1. Stop the system directly in uBoot: For this you have to press the spacebar on the
host computer keyboard before the boot delay time expires (default is 3 seconds).

2. Boot Linux: The system logs you in automatically as super user and the Linux shell
prompt is displayed on the screen.
