DIY Free Toolchain for Kinetis: Part 3 – Debugger (GDB Server with P&E and Segger)

This is the third part of a tutorial series how to ‘do-it-yourself’ a tool chain for the Freescale Kinetis microcontroller, with the FRDM-KL25Z as example. The tool chain is using GNU ARM gcc plus Eclipse Kepler release. So far I have the following parts:

So far things are very generic. But with debugging it means different hardware, and different hardware connections. And for this connection we need a GDB Server.

Eclipse CDT features a GNU Debugger (GDB), and this is what I want to use here: debugging my microcontroller with GDB inside Eclipse. In order to debug the microcontroller, I need two other things: a GDB Server and a Debug Probe.
