Installed openocd, Toolchain, Eclipse, How to proceed?

I have installed all the three components.

I am using Wiggler JTAG. I heard that we can do debug.

How to start, I am confuse. I have created the cfg file for my device IXp425 based. It has ntrst and strst seperate.

I mean to say do I need to use cfg first and then write my own script.

Please help.
