1 Prepare Development EnvironmentIf you want evaluate system via device integrated web pages,

you need have below items prepared:

● A host computer with browser pre-installed

● A network cable for the device which allow the host computeraccess the device

● Vantron provided dedicate 12V power adapter.

● Have already read the “Release Note” and are trying to followinstructions list in current “User Manual”.

If you want to login into device console via Telnet, SSH or UARTDebug Port, the below items are required.

● A Terminal Tool should be installed on the host computer(SecureCRT, PUTTY, or telnet/ssh/minicom of Linux).

● A female-male non-crossed RS232 cable, if you want login intothe Debug UART Console.

If you want to compile your own source code with Vantronprovided toolchain, and download it onto the device to start it, thebelow Operating System is suggested to be pre-installed on the hostcomputer.

● Ubuntu 11.10 64 bits, Ubuntu12.04 32bits and Ubuntu 10.04 32bits are verified to be okfor development. Other Linux popular distributions should be okbut not verified by Vantron.

12V DC into the power jack. Device will be powered up within 20seconds until a short buzz.

2.1 Web Page Login

Commonly the default IP address of L335 is “192.168.0.1”, thedefault login username and password are “admin/admin”. Thesesettings are listed in the Software Release Note, which might bevariable between different distributions.

The first login requires user to change the default username andpassword. These modified login settings will affect login via webpages, SSH and Telnet.

3 Advanced Console DebugBesides change and evaluate settings via web pages, users are

allowed to login into the device console, and then input commandsand check response to do some advanced debugging andevaluations.

3.1 Console LoginUsers can login into the console via TELNET or SSH, but first

need confirm these daemons (services) are set to start enabled.Login via serial debug is always allowed, a female-male serial cableshould be connected between the serial debug ports of VT-M2M-L335 device and a host computer.

The default login account and password are “root/admin”, thismight be different within different software distributions. Users aresupposed to get the login account from the Software Release Note.

[A sample to login via telnet on Linux Operating System]# telnet 192.168.0.1Default username: rootDefault password: admin

3.2 Console Test CommandsThis chapter describes all useful console commands. With these

commands, power on and off, data in and out would be manuallyestablished and controlled. This is very helpful when users are tryingto dig into the low level of implementation, or debugging attachedexternal module with Linux commands or tools and without thedisturb of web pages or exist logical process.

3.2.1 External Modules Power ControlBefore read from or write to one external module, the power of

that module should be enabled first. Under the file system directory“/sys/power”, most external modules have correspond powermanage entries. Writing 0 or 1 to these entries will cause thecorrespond modules being powered on or off.

The details of specific module will be described in the followingchapters. Here is a sample of 3G module.# echo “0” > /sys/power/3g-on // power on 3g module

# echo “1” > /sys/power/3g-on // power off 3g module# cat /sys/power/3g-on // check power status of 3gmodule

3.2.9 CANThis chapter describes a way to evaluate CAN communication

between two VT-M2M-L335 devices. If users have customized CANend devices and special data protocol that need customization fromVantron, please contact Vantron Support.

Prepare two VT-M2M-L335 devices, their CAN physicalconnection should be:

Device A Device BCANH <-> CANHCANL <-> CANLSend Data -> Receive Data

Then, first run candump on B# echo 1 > /sys/power/can_power# ip link set can0 type can bitrate 100000//Configure can, set can’s baud rate to 100000(100kbps) ~1000000(1000kbps)# ifconfig can0 up# candump can0

Send data from A# ifconfig can0 up# cansend can0 5A1#11.2233.44556677.88 // Data will print on B

3.2.10 Get CPU FreqCheck the current CPU freq:~ #cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

3.2.11 Bluetooth

If the Bluetooth PAN service has been started ,the chapter of3.1.15.1’s commands have been running.So we can overleap thecommands in this chapter.

3.2.12 Services InitAfter booting up the target, type the following command in turn tostart bluetoothd service.# start_bluetooth.sh (has already been started by default)# sdptool add --channel=10 OPUSH

Type command 'hciconfig <dev> piscan', other device would beseen it.# hciconfig 0 piscan[Note :] please do not use iphone to test this function, android is ok,the same 7056 is better.

3.2.15 Pair to other device

In some occasions, pairing other device may use pincodes.Disable the simple pairing, type command as bellow:# hciconfig 0 sspmode 0If in the disabled simple pairing mode, "0000" is the PIN.Input the previous PIN code at target device, pairing will be finished.

In simple pairing mode, (hciconfig 0 sspmode 1), tool "agent" mayusing simple mode PIN to pair.# agent --adapter hci0 --path /test/agent 0000 &

[Note:] hci0 is local bluetooth device, the dir "test/agent" couldchange, "0000" is the PIN.

In simple mode, other device pair to target will show the random PINcode in device,and will display in terminal.

In terminal:Confirmation request of 837114 for device/org/bluez/1898/hci0/dev_74_51_BA_E0_EB_97 //The "837114" isthe random PIN.

5 Update and boot

The board support to boot from on-board eMMC or externalMicro SD card. Booting from the external Micro SD card will makethe program debugging more convenient, because it’s very easy toupgrade the Micro SD content. Booting from on-board eMMC is astandard for Linux tablet, the on-board eMMC is the internalstorage, and the Micro SD card is the external storage. Everydistribution package released from Vantron must have identifiers toindicate the package is released for Micro SD booting, eMMCbooting, or both. If you need to change selection between the 2booting ways, you must know how to set the physical bootingjumpers.

Set S1 to 1100 (from PIN 1 to PIN 4, 0 means off while 1means on) , the board will boot from the on-board eMMC chip.This is the factory setting.

[Table 5-1 Boot Jumpers]

5.1 Update from Micro SD card

5.1.1 Making the Recovery Install tool SD driverTo make a recovery install tool SD driver, you need:

1. A 4GB or larger Micro SD card.2. An X86 PC runs Linux OS.

Then do like follow:1. Insert the Micro SD card into your host computer.2. Open a terminal window.3. Change to the root user, go to the release package then

execute the following commands to transfer the recoveryimage to the target device.~# cd img/sdcard/~# sudo ./usb_upgrade.sh ./vt-m2m-l335-usb-update-<date>-<MD5SUM>.tar.gz /dev/sdX

BOOT Mode Pin1 Pin2 Pin3 Pin4eMMC ON ON OFF OFFSD card OFF OFF ON OFF


Page 50 / Total 52

NOTE: Replace the placeholder /dev/sdX with the specificdevice file assigned to your Micro SD card when it wasinserted.If the Micro SD card mounted automatically when youinserted it (that is, if an icon appeared on the desktop or afile manager window opened), you must unmount it first.

4. After the command prompt returns and the activity light (ifany) on your flash drive stops blinking, remove the Micro SDcard from your PC.

5.1.2 Recovery to EMMC1. Set S1to 0010, connect the debug UART to the device.2. Insert the recovery install tool SD driver into the SD slot.3. Power on VT-M2M-L335 and login in, then execute:

# cd /opt/#./mkemmc.sh

4. Unplug the evaluation image recovery tool Micro SD card.5. Set S1 to 1100, then power on VT-M2M-L335.

5.2 Update kernel, u-boot, rootfs VIA Web PageWhen system is up, you can update system via web browser.

Please refer to chapter 2.6.5 Firmware Upgrade for more details.Again, update file for web page always has name of ‘vt-m2m-

l335-remote-upgrade-xos-<date>.tar.gz’.

5.3 Update m3 firmware VIA Web PageWhen system is up, you can update system via web browser.

Please refer to chapter 2.6.5 Firmware Upgrade for more detailsAgain, update file for web page always has name of ‘vt-m2m-

l335-m3app-remote-upgrade-xos-<date>.tar.gz’.

6 Restore Factory SettingsThere are three ways restore F/W back to factory settings.

6.1 Restore by pressing reset buttonKeep pressing Renew button more than 5 seconds, system will

restore factory settings and then follows a reboot. Partition etc anddata will slave.

6.2 Restore via web pageOpen a browser to access device’s web page ‘Administration ->

Factory Defaults’, select “YES” then click “Apply Settings”. Pleaserefer to chapter “2.6.4 Factory Defaults” for details. Partition etcand data will slave.

6.3 Restore all partsReset the device, at the same time, we press "Restore" button

until listen the beep on and off.
