Introduction to Device Provisioning

Introduction

Additional customization options allow OEM-specific changes to our product core. The Provisioning settings can be added to boot partition before the first boot or to data partition after the first boot. Below you will find an introduction to the different Device Provisioning options and step-by-step tutorial on how to add them to the correct partition.

Note: The OEM-specific device configuration used to be downloaded automatically during the installation of emteria.OS with the official installer application, now they need to be manually applied to the correct partition.

Note: The Device Provisioning is available in the Advance and Premium plan.

Watch our tutorial video forDevice Provisioning on our YouTube channel.

How to set up Device Provisioning in the Device Hub

Log in to yourDevice Hub.
Navigate toProvisioning.
Choose existing provisioning settings or create a new one.
Go throughdifferent options, set you your Provisioning settings, clickSaveandExport.
A .json file has been downloaded to your computer.

How to apply Provisioning settings before the first boot

Note: Before the first boot provisioning settings are added to the boot partition.

Install emteria.OS on a SDcard.
Insert it into your computer and mount it:
Right click onStart> right click onSDcard partition (usually BOOT (D:)) >Change Drive Letter and Paths >Add>Ok.
OpenFile Explorer >This PC >BOOT (D:)
Rename your downloaded .json file to oem.json and replace it with the one inside BOOT.
Insert SD card into your device and boot it up.

How to apply Provisioning settings after first boot

Note: After the first boot provisioning settings are added to the data partition.

Rename downloaded .json file to config.json file on your computer and connect your device to a network.
Use ADB to connect to your device with your computer.

After establishing connection write the following commands:

 adb push C:\Path\to\file\config.json /data/local/tmp/
 adb shell

Now that you have an open shell on the device, write the following commands:

 sushell
 mv /data/local/tmp/config.json /data/oem/config.json
 chown system:system /data/oem/config.json
 am start com.emteria.setupwizard/.activities.ResetActivity

After the last command, Setup Wizard will open for you to finish setting up your device.
After reboot, new settings will take affect.

Device Registration

With a Universal License present on your SD Card it will automatically reactivate devices which were already activated in the past, and it will also activate new devices automatically by assigning them unused licenses from the selected license group.

Universal licenses and License group had to be previosulsy set in Device Hub > Universal licenses. In provisioning you can only chose among those activation codes and it's group. device_registration-1

Note: For further information and explanation seeIntroduction to Universal Licenses.

During the initial device setup, you will see options for using these codes for automatic device activation.

System Settings

Here you can set settings to overwrite system default values.

system_settings

Example:

Section	Type	Key	Value	Comment

Global	Int	stay_on_while_plugged_in	7	Keep awake

Further reading:Android's documentation on Settings.

System Properties

Here you can set customized values for standard system properties.

Note: Modifying System Properties through Device Provisioning has advantages over e.g., altering the config.txt and cmdline.txt, as these changes are persistant over OTA updates.

system_properties

Examples:

Property name	Value	Comment
persist.rpi.connector.index	2
persist.rpi.cmdline	cmdline=video=HDMI-A-1:800x480M@60
persist.rpi.mode.force	800x480@60
persist.rpi.vc4.force	fkms
