Hello,
Licenses can be obtained via the https://www.nxp.com/gtmconfigtool website. If you are a new to the website, you will need to create a login account. Both trial and permanent licenses can be generated from there. For a trial license, select the 'Download' button. For the permanent license, select the 'Buy' button. You will be presented with an option to generate a license on the 'License Keys' tab on the Product Download page. Thereafter, you can proceed to 'My Account' and then 'Software Licensing and Support' to maintain your licenses and access updated product downloads.
Actually the above statement is not fully true as I had to go via NXP SW account to the GTM to be able to download the license.
The online request via GTM tool for license is not working for many years, as the email is sent to freescale email address which no longer exists.


Best regards,
Peter
