USB Drive Functions
Each Athena EST Unit device is configured with a series of possible USB Drive Functions; these are operations that take place when a USB drive is inserted into the device.
•Once a usb drive is inserted into the machine, a gui scrolled text screen will appear with important messages regarding the usb drive function (if a monitor is attached to the unit).
•All messages from the function will be logged in a file on the inserted USB during the operation
•In order for a USB to be validated and perform a USB Drive Function, it must contain a text file named sharedKey.txt which should match the sharedKey.txt file located in /home/pi/.est
•The name of the USB does not matter when executing USB Drive Functions
•The USB Drive Function to execute is determined by the state of the device and the name of the files or folder at the base level of the USB Drive
An EST Unit would be in the pre-owned state for one of three reasons:
•Recently purchased and not yet configured.
•The SD card had to be replaced.
When an EST Unit is in the pre-owned state there is only one possible USB Drive Function, "Take Ownership."
•Take Ownership: Configures the EST Unit to be owned by the specified user and configures the device for run time operations.
The directory structure of an owned USB Drive attempting to perform a USB Drive Function should be similar to the following:
USB Drive (E:)/
NOTE: The name of the 'USBFunctionDir' and the files it contains will vary between USB Drive Functions
•Providing WIFI Credentials to and Changing Network Settings on Targets, Monitors, and Displays
•Manually Installing a New EST Build and Downloading Definition Files
•Retrieving Local Logs from an EST Unit
To perform a USB Drive Function on an EST Unit, perform the following steps:
1.Configure the USB drive to match the file structure required by the wanted USB Drive Function
2.While an est unit is on and completely booted up, insert the USB drive into any USB port on the machine
3.Remove the usb after a message is displayed stating it is safe to do so. If no monitor is available (such as on the NC100 target), wait at least 30 seconds for the operation to complete .
Once the USB Drive Function is complete, a text log file should appear in the base of the USB, which should contain the date-time the USB was detected, the hostname of the machine the USB was inserted, and any debug messages that occurred during the function's execution.
