Xilinx never intended to support (uC)linux, so they wrote their own gdbserver-type program to run on the host, which then communicates with a stub on the target via a proprietary serial interface. So then, the question becomes: is there any info online about providing new arch support for gdb/gdbserver? Also looking at gdbserver version strings in the Makefiles - I see that gdbserver versions don't track gdb versions. In both the gdb5.0 and gdb5.1 distributions, the gdbserver version string is 4.12.3... ??? Thanks, John
