The BSP/SDK releases from NXP do follow a different development principle from working with upstream directly. However, we do value the customers who prefer to work closer with the upstream community than relying on our BSPs/SDKs deliveries and that's why we pushed our development team internally to upstream code as much as possible. And we will try to help keep them well maintained in the community. Regards, Leo
