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

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:
