3 Advanced Console Debug

Besides change and evaluate settings via web pages, users are allowed tologin into the device console, and then input commands and check responseto do some advanced debugging and evaluations.

3.1 Console Login

Users can login into the console via TELNET or SSH, but first needconfirm these daemons (services) are set to start enabled. Login via serialdebug is always allowed, a female-male serial cable should be connectedbetween the serial debug ports of VT-M2M-G335 device and a host computer.

The default login account and password are “root/admin”, this might bedifferent within different software distributions. Users are supposed to get thelogin 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 Commands

This chapter describes all useful console commands. With thesecommands, power on and off, data in and out would be manually establishedand controlled. This is very helpful when users are trying to dig into the lowlevel of implementation, or debugging attached external module with Linuxcommands or tools and without the disturb of web pages or exist logicalprocess.

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”, mostexternal modules have correspond power manage entries. Writing 0 or 1 tothese entries will cause the correspond modules being powered on or off.

The details of specific module will be described in the following chapters.Here is a sample of 3G module.# echo 0 > /sys/power/3g_power // power on 3g module# echo 1 > /sys/power/3g_power // power off 3g module

4 Update and boot

4.1 Boot Mode

The board support to boot from on-board eMMC or external Micro SD card. Bootingfrom the external Micro SD card will make the program debugging more convenient,because it’s very easy to upgrade the Micro SD content. Booting from on-board eMMCis a standard for Linux tablet, the on-board eMMC is the internal storage, and the MicroSD card is the external storage. Every distribution package released from Vantron musthave identifiers to indicate the package is released for Micro SD booting, eMMC booting,or both. If you need to change selection between the 2 booting ways, you must knowhow to set the physical booting jumpers.

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

[Table 5-1 Boot Mode Switch]

The Boot Mode Switch is set to “ON:ON:OFF:ON” by default, and the unit bootfrom the on-board eMMC.Before change the Boot Mode Switch, please unpack the cover of unit.

4.2 Booting fromMicro SD card

To make a bootable Micro SD card, you need:1. a 4GB or larger Micro SD card2. a X86 pc runs linux OS

Then do like following: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 recovery image to the targetdevice.

~# cd image/sdimg/~#sudo ./usb_upgrade.sh ./vt-m2m-G335-usb-update-<date>-<MD5SUM>.tar.gz/dev/sdX
