How to specify a non-initialised memory area in a LCF file

Hello all,

As my previous threads have indicated I am in the process of migrating an application from the HiCross compiler environment to the Metrowerks/CodeWarrior environment.

 

The application consists of a number memory areas:

 - SRAM - memory inside the MCU (68332)

 - APP_ROM - the application resides in Flash

 - NVRAM - non-volatile battery backed SRAM

 

I understand the MEMORY {} section and the flags for SRAM are set (RW) and APP_ROM to (R)

 

The question I have is how to specify the flags for the NVRAM area?

 

To mimic the non-volatile behaviour of this memory area I don't want it initialised, which I suspect setting the flags to (RW) will cause.

 

Any suggestions or comments?

Graham
