See attached patch. It's an updated "xmega" patch that includes support for 192a3 as well as other devices. Also take a look at the comments for avr.c in the patch. There it shows the classification of the devices. Those devices that are in an architecture that says "> 64K RAM" means the possibility of using external RAM. And yes this patch will be in the next toolchain release, of course. Eric
