Hi Again Gilles, I've also sent this mail to the DENX mailing list , since the toolchain is suplied by DENX. Our board was ported some two months ago by DENX software based on the MPC8272 (freescale) . I'd like to add the support for shared memory , but as I said I'd like to keep the system as untouched as possible - as I said It's been tested and is running stable and with good performance . Since I know that these things are delicate, I'd appreciate your guidance as to which files I need replaced (by which files) , and which configurations need be changed . Best Regards, Yigal Goldberger .
