I'm doing some work with a 5225x Coldfire and would like to be able to store certain variables In the battery backed-up first 16K of SRAM. We are using the 7.2 Code Warrior version, and Processor Expert... what's the easiest way to do this? I tried using define_section and __declspec() but was getting the "variable is referenced but has not been written" error from the linker. I suspect I have not set up the memory correctly... could you tell me how to do this with Processor Expert, or barring that how to edit the linker command file? Thanks! Ross
