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.

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

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.
