Hello Jon,
very nice project! Could you be more specific, what integration into the SDK you mean? There are more things
- adding a board just into the MCUXpresso desktop tools
- support the board in the Kinetis SDK (drivers, etc.)
- support the board in the online version
The first one is quite easy, but with the next version the tools will be more tight to the SDK library so it may be a challenge. For now (if it helps your needs) you can create a user template from existing configuration (using menu File | Export | Tools Configuration | Export Configuration as Template) that you can use later or distribute.
Regards,
Libor
