Debugging Arduino Due using SAM-ICE JTAG (an approach)

Hi All, I'm using the SAM-JTAG and Atmel Framework examples on a pvt SAM3X hw and also SAM3X-EK - I'm hoping to get a production Due when they arrive later this month at Digikey, Sparkfun etc.
I've brought in the Arduino DUE C++ framework to Atmel Studio 6, however when downloading through the JTAG I haven't bee able to put watches in the internal RAM.
I can get access to the peripheral memory map with the C drivers it seems - which is really nice

Anybody got the symbolics working and accessible with Atmels Studio C++ compiler?
