USB MSD Bootloader for MK22 with KDS 3.2

johnkozonasky — Thu, 08 Sep 2016 14:09:49 GMT

I'm developing a USB MSD bootloader following the structure of AN4379 for a MK22FN256VLH12 processor on a custom board with KDS 3.2, KSDK 1.2, and the PE USB Stack. Has this code been ported for this processor and development tools or are the original source files associated with this app note available to customize for my use?

Hi John

You can get a USB-MSD boot loader (device or host [memory stick] - or both at the same time) for the K22FN256 at

- http://www.utasker.com/kinetis/TWR-K22F120M.html
- http://www.utasker.com/kinetis/BLAZE_K22.html

It builds with KDS, CW, IAR, Keil, Rowley, Green Hills, GCC or Visual Studio and can be mixed with SD card, USB-HID KBOOT, and UART (KBOOT, SREC, IHEX, or AN2295 developer's serial loader) as required.

Hi John,

The KBOOT V2.0 has already provided the USB MSD approach to update the application, and in the KBOOT V2.0, you can find the corresponding demo for the MK22FN256VLH12.

You can learn the more information by referring to the post.
