BeagleBoard XM with XDS100v2
AFAIK the XDS100 emulators run only with the TI software. You should have gotten a board-locked license with you XDS100v2 - meaning that CCS runs only with exactly this adapter. (See the CCSv5 licensing FAQ for more information - it might even be that the normal CCSv5 installation already works with it)

Btw.: Code Composer Studio is based on Eclipse.

OpenOCD might be another way to go. Then you would install one of the GCC toolchains (code sourcery or yagarto, for example), and use OpenOCD. But for that you would need another JTAG adapter, since OpenOCD doesn't support the XDS series.
