[beagleboard] Using a Tiva C/Stellaris launchpad DebugOut interface as a JTAG emulator for BBB

[es]

Hello.
I've recently got a BBB and I am starting to play with it. Since I am used 
more to the bare-metal and low level work with microcontrollers, the first 
thing I am trying to figure out the JTAG interface to the board (probably I 
won't need it, but still..). Assuming that I have the JTAG connector 
soldered, I am trying to find a low cost JTAG emulator for the board. Since 
I have a stock of some hardware on my shelf I hope I have something that 
might fit . The most suitable solution that I am thinking of is to use TI's 
Tiva C Launchpad board, which can be connected as a ICDI/JTAG adapter to an 
external device as described here 
http://processors.wiki.ti.com/index.php/Stellaris_LM4F120_LaunchPad_Debug_How_To,
 
and then using openocd something like this:

openocd -f interface/ti-icdi.cfg -f target/am335x.cfg

Will this work? Is there anything to do to make it work?
Thank you.
