Eclipse GDB & OpenOCD Configuration

Does anyone have a working configuration set for Eclipse (Helios SR2) and OpenOCD (0.5.0) for integrated debug launch from Eclipse for an Atmel SAM3 target? The same information for any other Cortex M3 processor such as an STM32 or Stellaris will also be helpful.

I generally have OpenOCD and GBD functioning independent of Eclipse. I cannot state that the standalone operations are consistently repeatable. Eclipse with GDB Server and JLink works well. Online resources have been extensively searched and studied with limited useful information. GDB and OpenOCD documentation have also been studied. Most posts and instructions seem happy when the code is loaded into flash or ram. Very few, near zero, specifically address establishing a stable debug environment within Eclipse. The content and order of commands to GDB and OpenOCD from within Eclipse are all over the map with little or no explanation. I have access to a JTAGKey clone, JLink and Stellaris ICDI for testing. My available targets are SAM3S-EK, STM3210E, and EK-LM3S9B92.

This post is basically my last grasp for a solution before ditching OpenOCD.
