Accessing the ADTF-3175x

This section discusses how to access the command line interface (CLI) of the ADTF-3175x. Doing so gives the user access to Linux.

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:

sudo systemctl poweroff

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.

Making the SD Card Writable

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:

  • Windows FAT
  • Linux ext4

When the micro-SD card is inserted into a Windows machines the FAT partition will become available. For example:

Case 1: You computer does __not__ encrypt files on external storage devices.

  • Open the FAT partition that is available once the camera is connected
  • Open extlinux.conf file in the extlinux folder with notepad
  • Replace all ro with rw as shown below

Case 2: You computer encrypts files on external storage devices.

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)

  • Go to the partition properties and click on 'Advanced Sharing'

  • Check 'Share this folder' and create a name for the drive

  • In the properties folder copy the Network Path, and paste in File Explorer to open the drive

  • Modify the extlinux.conf file as mentioned in Case 1

Connecting to the ADTF-3175x

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.

  1. Plug the USB-C cable into the NXP to power up the device.
  2. Without the micro-USB cable connected to the ADTF-3175x device,
  3. Open 'Device Manager' on Windows. If you do not know how, please see the here.
  4. In the 'Device Manger' window, find 'Port (COM & LPT)', then expand the selection.
  5. Now plug in the micro-USB cable back into the ADTF-3175x.
  6. When booting is complete you should see a new COM port, note this COM port for use in PuTTY.

For example, in the case shown in the image below, the COM port is COM7.

Onto PuTTY:

  1. Open PuTTY
  2. You will see the 'Putty Configuration' window.
  3. In the 'Session' category: Select the 'Connection type' as 'Serial'; set the 'Serial line' to the value observed in the 'Device Manager'; set the 'Speed' to 115200; finally click 'Open'.
  4. PuTTY should open a terminal window at the login prompt of the ADTF-3175x.

Example of configuring PuTTY:

Example of opening PuTTY (note, you may need to press 'enter' to see the login prompt):

Logging into the ADTF-3175x

User name: analog Password: analog

Example of logging into the console of the ADTF-3175x via PuTTY.

Setting up Wifi

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.

  1. wpa_passphrase <SSIDOfYourNetwork> <Password> | sudo tee /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
  2. sudo systemctl enable wpa_supplicant@wlan0
  3. sudo reboot
