Getting Started with MCUXpresso SDK Package#
- Starting with version 25.09.00, MCUXpresso SDK introduced two package versions for offline development:
Classic SDK Package: Traditional board-specific packages with pre-configured IDE projects for MCUXpresso IDE, IAR, Keil, and other toolchains.
Repository-Layout SDK Package: Board-specific packages that maintain the same structure and build system as the GitHub Repository SDK, providing offline access to the repository SDK development experience. Available when selecting the ARMGCC toolchain.
- From version 25.12.00 onward:
When you select ARMGCC, the SDK download will use the Repository-Layout version.
For all other toolchains, the SDK download will remain in the Classic version.
Note: The Repository-Layout SDK package was first introduced in version 25.09.00, but initially only for MCXW23x platforms.
