G2Link

The Advanced View is for users with basic familiarity with a UNIX command line. It is primarily a terminal emulator, but also includes additional tools to retrieve or edit information from the display module. To open the Advanced View, on the main window’s menu bar click on View → Advanced View. The Advanced View will open in a new window.

There are three important parts of this window:

• Text Output Area: Occupies the bulk of the Advanced View window. When a command is run, messages will be displayed in this area. Text can be copied from this area, but it cannot be changed or edited. When the window is resized the output area will resize automatically.
• Command Input Field: To send a command to the display module, type it in this field and either click the Send button or press the Enter key on your keyboard. This will send the command to the display module, and the command and the output will show up in the Text Output Area above.
• Command Buttons: See descriptions below.

Debug QML Viewer

This button stops the QML Viewer, the TIO Agent, and the SIO Agent, and restarts them in debug mode. This causes the programs to print extra information on the Text Output Area, which can be useful when trying to determine why messages from the external controller are not being seen by the QML application.

Edit SIO Settings

This button brings up a dialog to edit the Serial IO Agent settings, which edits the /etc/init.d/sio-agent file on the display module. The TTY port and baud rate of the SIO Agent can be changed.

View Module Information

This button activates a popup dialog box and displays information about the display module.

• IP Address: This shows the display module’s IP address used to communicate over the network.
• MAC Address: A unique number used to configure the display module.

Not in the popup, but in the Text Output Area behind it, the Kernel Version data shows how Reach Technology built the software installed on the display module. This information cannot be changed, but it can be selected and copied to other applications.

Save Startup Messages

Retrieves debug information about the display module. After a moment, a dialog will appear asking where to save the information, which by default is saved as dmesg.txt.

Publish to Flash

Publish to Flash is used to copy your QML application from the SD Card to the NAND FLASH. Start by uploading the application to the display module (when booted from the SD Card). Then, in G2Link, click on Publish to Flash. Progress will be displayed in the Text Output Area, but be sure to wait until you see the Finished message before restarting the display module. Here is an example:

publish-flash.sh

Remember to move the jumper as described in the Using a Jumper to Select Boot Media section.

Restore Flash

Restore Flash is used to completely re-initialize the NAND FLASH from the SD Card. Start by writing the desired image to an SD Card, and boot the display module from that updated card. Then, in G2Link, click on Restore Flash. Progress will be displayed on the screen, but be sure to wait until you see the Done message before restarting the display module. Here is an example (edited for brevity):

Stop QML Viewer

When clicked the QML Viewer will stop and will not restart. The touch screen test will also forcibly quit.

Send Ctrl-C

This button forcibly stops a long-running command. It sends the Ctrl-C signal to the terminal. It is useful for commands like ping which will continue running until killed.
