Default PQ3 , vxworks and upgrading from 256MB DDR to 512MB issue

Hi,
we are trying to upgrade our PQ 3 based target
from 256MB ram to 512,

we work with vxworks 6.6 and compile under workbench
the BSP runs fine after we changed LOCAL_MEM_SIZE both under the wpj (affects vxworks(
and config.h (affects BSP), we changed rominit.s and syslib.c , MMU , and registers

the problem is , that after the vxworks is loaded , we can access just up to (256+64) MB
(also memShow doesn’t know more than that)

any help would be appreciated
Thanks
