1 Introduction

In the latest version of CoIDE, CooCox supports the FRDM-KL25Z from Freescale.

The FRDM-KL25Z is an ultra-low-cost development platform enabled by Kinetis L Series KL1

and KL2 MCUs families built on ARM® Cortex-M0+ processor. The board integrates an

onboard debugger called OpenSDA, which supports CMSIS-DAP.

This document mainly describes how to use OpenSDA to download and debug in CoIDE and

CoFlash.
