mc9s12xdt256 & Paged RAM

Hi,

 

Currently I am working with mc9s12dg256 controller.

Now I have to migrate to mc9s12xdt256AA controller but I have a problem with the paged RAM.

The RAM area of mc9s12dg256 (12KB) is not paged and firmware uses large RAM areas for memory allocation.

The problem is with RAM paged memory of mc9s12xdt256AA, that is 8KB unpaged and two pages of 4KB.

Since my firmware handles the RAM area as one piece, migration to new controller is really painful procedure.

 

Does anyone know if there is a way for codewarrior to handle the RAM of mc9s12xdt256AA controller as one piece.

 

Thank you

Nikos
