OpenSDA is a serial and debug adapter that is built into several NXP® evaluation boards. It provides a
bridge between your computer (or other USB hosts) and the embedded target processor, which can be used for
debugging, flash programming, and serial communication, all over a simple USB cable.
The OpenSDA hardware consists of a circuit featuring a Kinetis® K2x microcontroller with an integrated
USB controller. On the software side, it implements a mass storage device bootloader which offers a quick and easy
way to load OpenSDA applications such as flash programmers, run-control debug interfaces, serial to USB converters,
DAPLink is the new and improved implementation of mbed bootloader and standard debugging interface.
It includes a Kinetis K20-based circuit implementation that is portable to all OpenSDA v1 and v2/2.1, and new
version on a different Kinetis based circuit. For comparison between DAPLink and all OpenSDA version, please refer
