Macraigor's software does not currently support Xtensa processors. Your best bet is probably to obtain Tensilica software tools from the chip vendor, so that the tools match the particular configuration of the processor in that chip. Such tools normally include a version of GDB for the Xtensa architecture (xt-gdb) as well as the Xtensa OCD daemon which talks to xt-gdb on one side and supports a few JTAG probes including some Macraigor ones. -Marc (speaking for myself not for my employer, Tensilica)
