Software and driver considerations
The USB-KW019032 includes OpenSDAv2.1 (CMSIS-DAP), a serial and debug adapter circuit that
includes 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
the Kinetis K22F family. You can find more information in the KW019032 Quick Start Card.
To enter the bootloader mode and re-flash the CMSIS-DAP application, hold down the SW2 button while
plugging the USB-KW019032 board to the PC.
