OpenSDA Serial and Debug Adapter

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, and more.

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 to the table below on this page.

Comparison Table of Different OpenSDA Versions

*Note: During development of OpenSDAv2 the reserved bootloader space was found to be too small. Thus a new version of OpenSDAv2 was subsequently released and named, OpenSDAv2.1.

Version	Bootloader	Default Debugging Interface	Flash Programming	Virtual Serial Port	Source code available
OpenSDAv1	P&E Micro	P&E Micro	.sda/.s19/.srec	Yes	No, proprietary
OpenSDAv2	Arm/mbed	CMSIS-DAP	.bin	Yes	Yes, open source
OpenSDAv2.1	Arm/mbed	CMSIS-DAP	.bin	Yes	Yes, open source
