Leopard Board DM355 Hardware Setup

From Texas Instruments Embedded Processors Wiki

Setting up the Hardware

Follow the steps below to setup the hardware and enable communication with the Leopard Board. Verify that the Leopard Board's SW1 (boot from nand flash) switch is correctly set. Both positions to on.

Pin #	1	2
Position	1	1

• If you plan to use UART port for a console window, connect the serial cable to the serial port of your computer and to the UART port of your Leopard Board.

• If you want to use networking, connect the Ethernet cable to one of the Ethernet ports on the Leopard Board and to an Ethernet network port.

• Connect the power to your Leopard Board:

To power through USB: Connect the mini-B USB cable. The mini-B end to the J11 of Leopard Board and the type-A end to a USB port

Or Connect the power cable to the power jack on the board. To be safe, plug in the other end of the power cable only after you have connected the power cord to the board.

Connecting to a Console Window

You can open a console window that allows you to watch and interrupt the board's boot messages.

Steps to communicate with the board

1. Connect a serial cable between the serial port on the Leopard Board and the serial port (for example COM1) on a PC.

2. Run a terminal session (such as Minicom on Linux or TeraTerm on Windows) on the workstation and configure it to connect to that serial port with the following characteristics:

Bits per Second: 115200

Data Bits: 8

Parity: None

Stop Bits: 1

Flow Control: None

Transmit delay: 0 msec/char, 100 msec/line

Serial Device : /dev/ttyS0 (the device can change)

3. When you power on the Leopard Board, you will see boot sequence messages (If you have a boot loader in flash. If you do not have a boot loader in flash see the section). You can press a key to interrupt the boot sequence and type commands in the U-Boot command shell.
