Dumb question, did you recompile your kernel with those enabled ?

If nothing comes out, then you might need the help of a JTAG debugger.
You might want to try openocd though as it's open source and there are
many cheap JTAG debuggers which work with that (Flyswatter,
arm-usb-ocd, arm-usb-ocd-h, etc).
