S12 - XGATE shared memory in paged areas

I just started to program code for the XGATE on a S12XDP512 comnpiling with Cosmic. Everything works fine. -> Directing IRQ from S12 to XGATE, calling thread with a shared structure and giving Thread back to S12 by _sif().
Well, my problem is, that I don't want to use 'unpaged' RAM-pages for the structure shared on S12 and XGATE. I tryed to link the code to a paged RAM area with the result, that I can't access the variable structure on the S12 (declared with @far) but on XGATE.

Thanks for your reply.
