This section discusses how to access the command line interface (CLI) of the ADTF-3175x. Doing so gives the user access to Linux.
Out of the box, the user can write to the file system. However, any written data will be lost on reboot or power cycle of the device. The device can be setup such that changes to the file system survive reboots and power cycles. The following discussed how this can be done.
When operating the ADTF-3175x with a read/write partition it is highly recommended that Linux be shutdown prior to disconnecting power, not doing so may result in a corrupted file system. Issue the following command in the CLI to power down the system:
Disclaimer: It is rather easy to stop the proper functioning of the ADTF-3175x via an errant Linux command. The user is responsible for the state of the device once they start using the CLI. If the ADTF-3175x does stop functioning it is trivial to re-flash the stock micro-SD card image from the installation package.
The image for the micro-SD card is shipped with the Linux partition as read only. It is possible to make the Linux partition read-write.
Once again, not the introduction at the top of this page.
The micro-SD card image has two partitions:
When the micro-SD card is inserted into a Windows machines the FAT partition will become available. For example:
If your organization encrypts file transfers to external drives, it is recommended to use a personal pc to run this step. Once the change is made it is permanent and the user can go back to their work PC.
If using a personal PC is not an option, mapping the windows partition as a network drive could allow the user to bypass encryption (Although your mileage may vary)
Connecting to the ADTF-3175x is accomplished via a USB-Serial link via micro-USB cable. Referring to the below, the micro-USB port is shown in the red circle.
We use PuTTY for a terminal. PuTTY can be downloaded from here (PuTTY download).
Before running PuTTY we need to discover the COM port of the device.
For example, in the case shown in the image below, the COM port is COM7.
Example of configuring PuTTY:
Example of opening PuTTY (note, you may need to press 'enter' to see the login prompt):
The ADTF-3175x device has Wifi support. Through the Wifi connection it is possible to connect to a router then to the Internet. Having Wifi
Setting up Wifi is as easy on the ADTF-3175x as it would be on any Ubuntu device.
