Hi
USB memory stick loader is available for almost all Kinetis parts in the Open Source uTasker project which can be downloaded from GITHUB:
Web: https://github.com/uTasker/uTasker-Kinetis
HTTPS: https://github.com/uTasker/uTasker-Kinetis.git
SSH: git@github.com:uTasker/uTasker-Kinetis.git
Documentation at http://www.utasker.com/docs/uTasker/uTaskerSerialLoader.PDF
Can also work as USB-MSD device loader or Memory stick loader (automatically detects the mode to use) as well as composite KBOOT compatible, SD card or various others.
Builds with 10 different IDEs, includes in-built support for about 50 Kinetis development boards (no porting required between parts), smaller code size than the examples in KSDK and can be completely simulated in Visual Studio for optimal development efficiency if customising is desired (proven in many industrial products on a multitude of memory sticks and so risk-free).
For professional use, one-on-one support is also available.
Regards
Mark
