Hello Jonathan,
The TWR comes flashed with the Connectivity Test demo, you can reflash it by drag/drop the demo in the OpenSDA MSD. You can find that binary file within the TWR-KW2x_Board Support Package (www.freescale.com/TWR-KW2x --> Download tab) and other Zigbee/MAC/SMAC demos.
For additional demos and documentation, please download BeeKit Wireless Connectivity Toolkit, also located in same place as the Board Support Package (BSP).
You can find TWR documentation under (--BeeKit Installation folder--)\Documentation\Development Kit Documents
Note:
Latest OpenSDA firmware incorporates Mass Storage Device(MSD) and Debug Application functionality in the same build. Current TWR-KW2x comes preloaded with only MSD application.
Download latest OpenSDA firmware at www.pemicro.com/opensda and follow the steps in the TKW2x_OSDAUG_v1.1.pdf (Located in BSP and BeeKit documentation) guide to upgrade the OpenSDA firmware.
Hope this is useful information!
Best Regards,
Juan Carlos Pacheco
