CCS error while launching target configuration

Hi,

I am running a few basic codes beaglebone black for which I need debug trace. For getting started with debugging I read the following post:

http://beagleboard.org/static/Docs/ccs-jtag-simple.htm

I have installed version 5.1 of CCS as mentioned in the post and copied the ccxml file in the respective location. But when I try to launch configuration, I get an error which says:

Error connecting to the target:

(Error - 151 @ 0x0)

This utility failed to open for4 a custom emulator.

The adapter returned an error.

(Emulation package 5.0.520.0)

Please tell me where could I wrong.
