If you have purchased the development license (USB dongle), you will need to upgrade the evaluation architecture packs that come preinstalled with MicroEJ SDK with the production architecture packs.
Here is how to do it :
connect to the https://license.microej.com server using your MicroEJ account
click on the Public P/N hyperlink below the MicroEJ® SDK (Production) product
Download the production architectures archive
Follow the instructions in the HOWTO.md file
If you have a pre-activated dongle by MicroEJ and this dongle is not linked to your license account, you need to request the MicroEJ production architectures link to our support team (firstname.lastname@example.org).
