Before Using the Product

This chapter provides information you should know before using the product.

About the Unit

This product is a micro controller that employs an on-board high precision Marvell Kirkwood SoC with

integrated ARM® processor.

The high precision Marvell Kirkwood SoC with integrated 1.2GHz ARM® processor has 512 MB of

DDR2 SDRAM system memory. For storage, this product employs cost-effective microSD cards and

also supports high-speed, high-capacity microSDHC cards.

Optimal for applications that require a controller that takes up less power and space than a PC.

Features

- Fan-less operation reinforcement platform

The high precision Marvell Kirkwood SoC with integrated 1.2GHz ARM® processor employs a generic

open source platform with 512MB of system memory.

- Employs Linux OS

Linux OS (Kernel 2.6) utilizes an extensive series of open source libraries, allowing a broad range of

field-specific applications to be constructed freely.

- High reliability operation, 24 hours a day, 365 days a year

Optimal for use in situations where 24hr/365 day a year maintenance-free operation is required, such as

the information communication terminal of a home gateway or router, smart meter or solar power

managing terminal, or appliance devices such as biometric security systems.

The root password is "root".

Use /dev/mtdblock0 as /.

When the data is mounted as read only. To read/write to the data remount with parameters #

rommode rw.

When the data is mounted as read/write. To read only to the data remount with parameters #

rommode ro.

Get the IP address for eth0 (B side) from dhcpclient.

At /etc/dhcp3/dhclient-enter-hooks, create /tmp/resolv.conf for dns and /tmp/named.conf.options for

bind.

Set iptable at /home/filter.sh and launch from /etc/network/interface.

When setting “eth0” to “DHCP client”,

edit “/etc/network/interface”.

auto eth0

iface eth0 inet dhcp

When setting “eth0” to a fixed IP address.

(An example)

Edit “/etc/network/interface”.

iface eth0 inet static

address 192.168.3.1

netmask 255.255.255.0

gateway 192.168.3.251

eth1 (A side) has a static IP address (192.168.1.254).

Perform initial settings at /home/rc.local.a.

The DHCP server boots up at eth1.

The settings are logged in /etc/dhcp3/dhcpd.conf.

3. Setup

SSH grants root login permissions to eth0 and eth1.

Perform any necessary settings.

#ssh-keygen -b 2048 -t rsa -P xxxx

If using the serial console, download the serial drivers from the following site:

http://www.ftdichip.com/Drivers/VCP.htm

http://www.ftdichip.com/Drivers/CDM/CDM20808.zip

Connect a USB cable between the MC-300 USB port (miniB) and the computer. You can now login to

the serial console.

(Serial settings: Baud Rate: 115200bps, Data: 8bit,

Parity: none, Stop: 1 bit, Flow control: none)

Connect the miniB cable to the USB (miniB) port on the MC-300 after it starts. Every time after

rebooting, the serial chip is reset and the computer terminal software must be restarted.

You can disable the serial chip reset by setting the facade DIP switch (SW1) to ON, however this

feature is meant for debugging so please ensure that this switch is normally set to OFF.

When displaying the U-Boot command prompt, the DIP switch (SW1) must be set to ON.

3. Setup

MC-300B-DC5-455

About the 100Mbps LAN

The factory setting is 100Mbps Full Duplex.

If setting to Half Duplex, or resetting Full Duplex, perform the following:

Set to 100Mbps Full Duplex setting at /home/rc/local.a.

< When setting to 100Mbps Full Duplex (Factory setting)>

/usr/sbin/ethtool -s eth0 speed 100 autoneg off

/usr/sbin/ethtool -s eth1 speed 100 autoneg off

Set any other connected devices or hub to 100Mbps Full Duplex.

If connected to a device that does not allow this setting, set the connected device to 100Mbps Half

Duplex.

< When setting to 100Mbps Half Duplex >

/usr/sbin/ethtool -s eth0 speed 100 duplex half autoneg off

/usr/sbin/ethtool -s eth1 speed 100 duplex half autoneg off

How to mount Read only

The damage of NAND Flash due to the power failure etc. can be reduced by changing to the setting into

which NAND Flash (/dev/mtdblock0) mount with read only after an installation and various settings of

the application are completed.

1) MC-300 is started, and MC-300 does serial connection by using the USB cable and logs it in.

<Default when factory is shipped> user : root, passwd : root

2) A front DIP switch (SW1) is turned on.

3) It reactivates.

# reboot

4) It presses return key by U-Boot, and the command of U-Boot is input.

5) The environmental setting is changed.

Marvell> setenv bootcmdra 'setenv bootargs console=ttyS0,115200 root=/dev/mtdblock0 ro

rootwait rootfstype=jffs2 mtdparts=nand_mtd:0x1BFE0000@0x4020000(mtdfs)rw'

The command of setenv is input by one line.

6) The setting is preserved.

Marvell> saveenv

7) It reactivates.

Marvell> reset

8) A front DIP switch (SW1) is turned off.

It will move from next time with read only when the above-mentioned is set.

Please set it by 5) as follows when you make the start default read/write.

Marvell> setenv bootcmdra 'setenv bootargs console=ttyS0,115200 root=/dev/mtdblock0 rw

rootwait rootfstype=jffs2 mtdparts=nand_mtd:0x1BFE0000@0x4020000(mtdfs)rw'

The command of setenv is input by one line.
