3.1

Unpacking

Warning:

This board contains static sensitive devices.

The EVALSPEAr320HMI evaluation board is shipped in protective anti-static packaging. Do

not submit the board to high electrostatic potentials, and follow good practices for working

with static sensitive devices.

●

Wear an anti-static wristband. Wearing a simple anti-static wristband can help

prevent ESD from damaging the board.

●

Zero potential. Always touch a grounded conducting material before handling the

board, and periodically while handling it.

●

Use an anti-static mat. When configuring the board, place it on and anti-static mat to

reduce the possibility of ESD damage.

●

Handle only the edges. Handle the board by its edges only, and avoid touching board

components.

3.2

Connecting

Carefully plug the CPU board into the expansion board.

On the EVALSPEAr320CPU board, set Switch 2 to parallel NAND 8 boot mode:

Connect a serial cable from the expansion board (connector CN500: RS232_0/UART0)

to the host PC (see Figure 2: Expansion board layout).

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

Connect a power supply to the SPEAr320 HMI evaluation board as described in

Section 4.6: Power supply on page 15.

Apply power to the board. The Terminal program displays a sequence of boot

messages followed by the Linux console prompt.

For more information, refer to user manual UM0844, Getting started with Linux for SPEAr,

available at www.st.com/spear.

3.3

Booting

The SPEAr320 HMI evaluation board can boot a Linux kernel pre-installed in the parallel

NAND 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:

●

Stop the system directly in uBoot: Before the boot delay time expires (default is

3 seconds), press the spacebar on the host computer’s keyboard.

●

Boot Linux: The system boot is finished when the login prompt appears in the console.

The default login user name for super user is root; no password is required.

Positions 1, 4, 6, and 7: Off

Positions 2, 3, 5, and 8: On
