Getting start to know ARM-based debug system

It's a VERY VERY late post.

When I was stuck on porting Qi on the beagleboard, the first thought is to use openOCD to see where problem is. Unfortunately, the support for ARM cortex A8 is provided but not full functional. The good thing of opensource is, anything goes wrong or you don't like it, you can just fix by yourself. But the assumption is, you need to know how to fix. So I can't help myself to start to learn the knowledge about ARM debug system. After the co-work with Holger, my ex-colleague, we have some progress to make openOCD work as we expect. He also posted the thing on his blog:

If you are interesting with how to get familiar with ARM-based debug system for Cortex A8, Magnus provides a great introduction:
