Set static IP: Stop the DHCP process
advantech# /etc/init.d/dhcpc eth0 stop advantech# /etc/init.d/dhcpc eth1 stop
Set the static IP as below.
advantech# /sbin/ifconfig eth0 172.21.73.191 netmask 255.255.255.0 advantech# /sbin/route add default gw 172.21.73.253 eth0 advantech# echo 'nameserver 172.21.128.251' >> /etc/resolv.conf advantech# /sbin/ifconfig eth1 192.168.3.102 netmask 255.255.255.0 advantech# /sbin/route add default gw ... eth1 advantech# echo 'nameserver 172.21.128.251' >> /etc/resolv.conf
If you want to reserve the setting after rebooting the device, set as below
advantech# echo "/sbin/ifconfig eth0 172.21.73.191 netmask 255.255.255.0; /sbin/route add default gw 172.21.73.253 eth0;echo 'nameserver 172.21.128.251' > /etc/resolv.conf;" > /etc/adv.d/netcfg.eth0 advantech# echo "/sbin/ifconfig eth1 192.168.3.102 netmask 255.255.255.0; /sbin/route add default gw ... eth1;echo 'nameserver 172.21.128.251' > /etc/resolv.conf;" > /etc/adv.d/netcfg.eth1

Matrix GUI User‘s Guide
Overview
When you boot up the target system, Matrix GUI should be automatically started. Matrix is an HTML 5 based application launcher created to highlight available applications and demos provided. There are two forms of Matrix, local and remote Matrix. All of the example applications and demos are available using either the local or remote version. Matrix comes as a 6x4 matrix of icons or as a 4x3 matrix depending on the display resolution. The launcher for Matrix is just a simple QT application that displays a Webkit base browser that points to the URL http://localhost:80. 
Launching and Stopping Matrix
If the Matrix GUI does not start with the system, you can manually start the program by the following command:
advantech# /etc/init.d/matrix-gui-2.0 start
If you want the Matrix to start with the system by default, please run the following command
advantech# cp /etc/init.d/matrix-gui-2.0 /etc/rc5.d/S97matrix-gui-2.0
When you want to cancel the default startup, just remove the S97matrix-gui-2.0 file. For more information on the use of Matrix, please refer to the following website: http://processors.wiki.ti.com/index.php/Matrix_Users_Guide.
Adding a Matrix Application
Below are step-by-step instructions for Adding a New Application/Directory to Matrix.
- Create a new folder on your target file system at /usr/share/matrix-gui-2.0/apps/. The name should be a somewhat descriptive representation of the application or directory. The folder name must be different from any existing folders at that location.
- Create a desktop file based on the parameters discussed below. It is recommended the name of the desktop file match the name of the newly created folder. No white spaces can be used for the desktop filename. The desktop file parameters should be set depending on if you want to add a new application or a new directory to Matrix. The Type field must be set according to
your decision. The desktop file must have the desktop suffix.
- Update the Icon field in the desktop to refer to any existing Icon in the /usr/share/matrix-gui-2.0 directory or subdirectories. You can also add a new 96x96 png image and place it into your newly created folder.
- Optionally for applications you can add a HTML file that contains the application description in your newly created directory. If you add a description page then update the X-Matrix-Description field in the .desktop file.
- Refresh Matrix using the application "Refresh Matrix" located in the Settings submenu. Blank template icons for Matrix can be found here:
http:// gforge.ti.com/gf/download/frsrelease/712/5167/blank_icons_1.1.tar.gz The .desktop file is based on standard specified at the URL: http:// standards.freedesktop.org/desktop-entry-spec/latest/ Additional fields were added that are unique for Matrix. Format for each parameter: <Field>=<Value> The fields and values are case sensitive.
Screen rotation for Qt application
Please export the Environments:

- Remove a Startup items:
update-rc.d [-n] [-f] [-r <root>] <basename> remove
basename is your service script name
eg. update-rc.d -f matrix-gui-2.0 remove
- Add a Startup items:
Firstly,You must ensure that the service script is exists,then run the flowing command:
update-rc.d [-n] [-r <root>] [-s] <basename> start|stop NN runlvl [runlvl] [...] .
start|stop : when system start /shutdown the basename wiil run automatically
NN: 0~99
runlvl: advantech AM335x platform runlevel is 5(default);
eg. update-rc.d networking start 40 5 .
then you can find the S40networking in rc5.d directory;
