Licenses¶

SDK EULA¶

MICROEJ SDK is licensed under the SDK End User License Agreement (EULA), which covers the following elements:

SDK Tools & Plugins packaged in the SDK 5.x Version,
Architectures,
Modules published to the Central Repository with the SDK EULA license, such as GUI or Networking Pack (see Central Repository Licensing for more details).

SDK EULA Coverage¶

License Manager Overview¶

Architectures are distributed in two different versions:

Evaluation Architectures, associated with a software license key. They can be downloaded at https://repository.microej.com/modules/com/microej/architecture/.
Production Architectures, associated with a hardware license key stored on a USB dongle. They can be requested to our support team.

The license manager is provided with Architectures and then integrated into Platforms, consequently:

Evaluation licenses will be shown only if at least one Evaluation Architecture or Platform built from an Evaluation Architecture has been imported in the SDK.
Production licenses will be shown only if at least one Production Architecture or Platform built from a Production Architecture has been imported in the SDK.

The list of installed licenses is available in the SDK preferences dialog page in Window > Preferences > MicroEJ:

License Manager View¶

License Check¶

The table below summarizes where the license is checked.

Application	Run on Simulator (Virtual Device)	Build on Device	Documentation Link
Standalone Application or Kernel Application	NO	YES	Run on the Device
Sandboxed Application	NO	NO	Application Linking

Evaluation Licenses¶

This section should be considered when using Evaluation Architectures, which use software license keys. A machine UID needs to be provided to activate an Evaluation license on the MicroEJ Licenses Server. The machine UID is a 16 hexadecimal digits number.

Get your Machine UID¶

Retrieving the machine UID depends on the kind of MicroEJ Platform being evaluated.

If your MicroEJ Platform is already imported in Package Explorer and built with MicroEJ Module Manager, the Architecture has been automatically imported. The machine UID will be displayed when building a MicroEJ Standalone Application on device.

[INFO ] Launching in Evaluation mode. Your UID is XXXXXXXXXXXXXXXX.
[ERROR] Invalid license check (No license found).

Otherwise, an Architecture or Platform should have been manually imported from the SDK preferences page. The machine UID can be retrieved as follows:

Go to Window > Preferences > MicroEJ,
Select either Architectures or Platforms,
Click on one of the available Architectures or Platforms,
Press the Get UID button to get the machine UID.

Note

To access this Get UID option, at least one Evaluation Architecture or Platform must have been imported before (see License Manager Overview).

Copy the UID. It will be needed when requesting a license.

Machine UID for Evaluation License¶

Request your Activation Key¶

Go to MicroEJ Licenses Server https://license.microej.com.
Click on Create a new account link.
Create your account with a valid email address. You will receive a confirmation email a few minutes after. Click on the confirmation link in the email and log in with your new account.
Click on Activate a License.
Set Product P/N: to 9PEVNLDBU6IJ.
Set UID: to the machine UID you copied before.
Click on Activate.
The license is being activated. You should receive your activation by email in less than 5 minutes. If not, please contact our support team.
Once received by email, save the attached zip file that contains your activation key.

Install the License Key¶

If your MicroEJ Platform is already imported in Package Explorer and built with MicroEJ Module Manager, the license key zip file must be simply dropped to the ~/.microej/licenses/ directory (create it if it doesn’t exist).

MicroEJ Shared Licenses Directory¶

Note

The SDK Preferences page will be automatically refreshed when building a MicroEJ Standalone Application on device.

Otherwise, the license key must be installed as follows:

Go back to the SDK.
Select the Window > Preferences > MicroEJ menu.
Press Add….
Browse the previously downloaded activation key archive file.
Press OK. A new license is successfully installed.
Go to Architectures sub-menu and check that all Architectures are now activated (green check).
Your SDK is successfully activated.

If an error message appears, the license key could not be installed. (see section Troubleshooting). A license key can be removed from the key-store by selecting it and by clicking on Remove button.

Troubleshooting¶

Unable to add an Evaluation license key¶

Consider this section when an error message appears while adding the Evaluation license key. Before contacting our support team, please check the following conditions:

Key is corrupted (wrong copy/paste, missing characters, or extra characters)
Key has not been generated for the installed environment
Key has not been generated with the machine UID
Machine UID has changed since submitting license request and no longer matches license key
Key has not been generated for one of the installed Architectures (no license manager able to load this license)

Invalid License Key Error Message¶

Machine UID has changed¶

This can occur when the hardware configuration of the machine is changed (especially when the network interfaces have changed).

In this case, you can either request a new activation key for this new UID or go back to the previous hardware configuration.

Production Licenses¶

This section should be considered when using Production Architectures, which use hardware license keys stored on a USB dongle.

MicroEJ USB Dongle¶

Note

If your USB dongle has been provided to you by your sales representative and you don’t have received an activation certificate by email, it may be a pre-activated dongle. Then you can skip the activation steps and directly jump to the Check Activation on SDK section.

Request your Activation Key¶

Go to license.microej.com.
Click on Create a new account link.
Create your account with a valid email address. You will receive a confirmation email a few minutes after. Click on the confirmation link in the email and login with your new account.
Click on Activate a License.
Set Product P/N: to The P/N on the activation certificate.
Enter your UID: serial number printed on the USB dongle label (8 alphanumeric char.).
Click on Activate and check the confirmation message.
Click on Confirm your registration.
Enter the Registration Code provided on the activation certificate.
Click on Submit.
Your Activation Key will be sent to you by email as soon as it is available (12 business hours max.).

Note

You can check the My Products page to verify your product registration status, the Activation Key availability, and download the Activation Key when available.

Once the Activation Key is available, download and save the Activation Key ZIP file to a local directory.

Activate your USB Dongle¶

This section contains instructions that will allow you to flash your USB dongle with the proper activation key.

You shall ensure that the following prerequisites are met :

Your operating system is Windows
The USB dongle is plugged and recognized by your operating system (see Troubleshooting section)
No more than one USB dongle is plugged into the computer while running the update tool
The update tool is not launched from a network drive or a USB key
The activation key you downloaded is the one for the dongle UID on the sticker attached to the dongle (each activation key is tied to the unique hardware ID of the dongle).

You can then proceed to the USB dongle update:

Unzip the Activation Key file to a local directory
Enter the directory just created by your ZIP extraction tool.
Launch the executable program.
Accept running the unsigned software if requested (Windows 10)
Click on the Update button (no password needed)

Dongle Update Tool¶
On success, an Update successfully message shall appear. On failure, an Error key or no proper rockey message may appear.

Successful Dongle Update¶

Check Activation on SDK¶

Note

Production licenses will be shown only if at least one Production Architecture or Platform has been imported before (see License Manager Overview).

Go back to the SDK,
Go to Window > Preferences > MicroEJ,
Go to Architectures or Platforms sub-menu and check that all Production Architectures or Platforms are now activated (green check).

Platform License Status OK¶

USB Dongle on GNU/Linux¶

For GNU/Linux Users (Ubuntu at least), by default, the dongle access has not been granted to the user, you have to modify udev rules. Please create a /etc/udev/rules.d/91-usbdongle.rules file with the following contents:

ACTION!="add", GOTO="usbdongle_end"
    SUBSYSTEM=="usb", GOTO="usbdongle_start"
    SUBSYSTEMS=="usb", GOTO="usbdongle_start"
    GOTO="usbdongle_end"

    LABEL="usbdongle_start"

    ATTRS{idVendor}=="096e" , ATTRS{idProduct}=="0006" , MODE="0666"

    LABEL="usbdongle_end"

Then, restart udev: /etc/init.d/udev restart

You can check that the device is recognized by running the lsusb command. The output of the command should contain a line similar to the one below for each dongle: Bus 002 Device 003: ID 096e:0006 Feitian Technologies, Inc.

USB Dongle with Docker on Linux¶

If you use the SDK Docker image on a Linux host to build a Firmware, the dongle must be mapped to the Docker container. First, it requires to add a symlink on the dongle by following the instructions of the USB Dongle on GNU/Linux section but with this /etc/udev/rules.d/91-usbdongle.rules file:

ACTION!="add", GOTO="usbdongle_end"
    SUBSYSTEM=="usb", GOTO="usbdongle_start"
    SUBSYSTEMS=="usb", GOTO="usbdongle_start"
    GOTO="usbdongle_end"

    LABEL="usbdongle_start"

    ATTRS{idVendor}=="096e" , ATTRS{idProduct}=="0006" , MODE="0666" , SYMLINK+="microej_dongle"

    LABEL="usbdongle_end"

Then the symlink has to be mapped in the Docker container by adding the following option in the Docker container creation command line:

--device /dev/microej_dongle:/dev/bus/usb/999/microej_dongle

The /dev/microej_dongle symlink can be mapped to any device path as long as it is in /dev/bus/usb.

Troubleshooting¶

This section contains instructions to check that your operating system correctly recognizes your USB dongle.

Windows Troubleshooting¶

If the dongle activation failed with No rockey message, check there is one and only one dongle recognized with the following hardware ID :
```
HID\VID_096E&PID_0006&REV_0201
```
Go to the Device Manager > Human Interface Devices and check among the USB Input Device entries that the Details > Hardware Ids property match the ID mentioned before.
If the dongle activation was successful with Update successfully message but the license does not appear in the SDK or is not updated, try to activate again by starting the executable with administrator privileges:
If the following error message is thrown when building a MicroEJ Firmware, either the dongle plugged is a verbatim dongle or it has not been successfully activated:
```
Invalid license check (Dongle found is not compatible).
```

VirtualBox Troubleshooting¶

In a VirtualBox virtual machine, USB drives must be enabled to be recognized correctly. Make sure to enable the USB dongle by clicking on it in the VirtualBox menu Devices > USB.

To make this setting persistent, go to Devices > USB > USB Settings… and add the USB dongle in the USB Devices Filters list.

Remote USB Dongle Connection¶

When the dongle cannot be physically plugged to the machine running the SDK (cloud builds, virtualization, missing permissions, …), it can be configured using USB redirection over IP network.

There are many hardware and software solutions available on the market. Among others, this has been tested with https://www.net-usb.com/. Please contact our support team for more details.
