3.3 Serial and debug adapter
The USB-KW40Z development board can be enabled with OpenSDA v2.1, a serial and debug adapter
circuit that includes an open-source hardware design, an open-source bootloader, and debug interface
software. It bridges serial and debug communications between a USB host and an embedded target
processor. The hardware circuit is based on a Freescale Kinetis K22F family microcontroller (MCU).
OpenSDAv2.1 enables the CMSIS-DAP bootloader, an open-source mass storage device (MSD)
bootloader, and the CMSIS-DAP Interface firmware (also known as the mbed interface), that provides a
MSD flash programming interface, a virtual serial port interface, and a CMSIS-DAP debug protocol
interface. For more information on the OpenSDAv2.1 software, see mbed.org and
https://github.com/mbedmicro/CMSIS-DAP.
NOTE
Driver considerations, you must install a windows driver that can be
downloaded from the following link:

USB-KW40Z comes pre-programed with a sniffer application. In order to enable this board with
OpenSDA feature and as a development board, refer to the following:
