Introduction

This Quick Start Guide explains the basics: how to connect and set up your target on the network; how to install the SDK; and how to build the firmware images. For more detailed information, refer to the User Guide supplied with this product or our Lantronix Web site www.lantronix.com/support/downloads.

Overview

The Lantronix Linux Software Developer’s Kit (SDK) is an embedded hardware and software suite that enables Linux developers to create applications on Lantronix’ embedded networking modules.
The MatchPort AR module can be used to add networking capabilities to your device. The development board includes two RS-232 serial ports and a 10 /100Base-TX network connection (RJ45).
The XPort Pro module can be used to add networking capabilities to your device. The development board includes an RS-232 serial port and a 10/100Base- TX network connection (RJ45).
The EDS1100 & EDS2100 are external device servers that can be used to add networking capabilities to your device. The EDS1100 has one RS-232 serial port and a 10/ 100Base-TX network connection (RJ45). The EDS2100 has two RS-232 serial ports and a 10/100 Base-TX network connection (RJ45). Based on the 2.6 Linux kernel, and leveraging existing open source software, the SDK simplifies the process of adding custom applications. Device drivers, GNU toolchain, pre- defined configuration profiles, and sample applications are all included

Connecting an Evaluation Board – Ethernet

**One Step** Connect the PC to the evaluation or demo board with a cross- over cable, or a hub/switch and two regular RJ45 cables.

1. Select the appropriate power plug adaptor for your geographical location. Insert it into the slot on the Universal Power Supply; then plug the power supply into an outlet.
2. Connect the output plug of the power supply to the EDS1100/EDS2100.
3. Connect one end of the supplied DB9F/F (DB25F on EDS1100) serial cable to the serial port on the laptop or desktop.
4. Connect the other end of the supplied serial cable to the serial port on the EDS1100 (CON1 on EDS2100).
5. Connect the PC to the evaluation or demo board with a cross-over cable, or a hub/switch and two regular RJ45 cables.

Booting the Target Device

To boot your target device (MatchPort AR, XPort Pro, or EDS1100 / 2100):

1. From the host computer, open a terminal emulation program for the serial port.
2. Configure the following serial port settings:
   • baud rate: 115200
   • data length: 8
   • parity: None
   • stop bit: 1
   • flow control: None
3. Turn the power on.
   A series of boot messages displays before the Linux shell prompt of ‘#’ appears.

Configuring an IP Address

By default, the target device (MatchPort AR, XPort Pro, or EDS1100 / 2100) will attempt to obtain an IP address via the DHCP protocol. Type the following command at the Linux shell prompt to determine the IP address:

$ ifconfig eth0
The ifconfig command can also be used to set an address, but it will not persist across a reboot.

To set a temporary static address, issue the following command (replace angle bracketed items with actual values):
$ ifconfig eth0

To set a static address that persists across reboots:

1. Use the vi text editor to edit /usr/local/etc/netcfg. (Consult a vi manual for details on using this text editor).
2. Add the following lines to the netcfg file (replace angle bracketed items with actual values) IPADDR= NETMASK= GATEWAY=
3. Write the changes to the file and exit the from the vi editor. 4. Issue the ‘reboot’ command to reset the target for changes to take effect.

To set a static address that persists across reboots:

1. Use the vi text editor to edit /usr/local/etc/netcfg. (Consult a vi manual for details on using this text editor).

2. Add the following lines to the netcfg file (replace angle bracketed items with actual values)
   IPADDR=
   NETMASK=
   GATEWAY=

3. Write the changes to the file and exit the from the vi editor.

4. Issue the ‘reboot’ command to reset the target for changes to take effect.
