Help! Problem in linking!

Hi Dugufei,

I sometimes get this error when trying to access data in a different section. I have a section of battery-backed SRAM, away from the RAM used for my code and bss. To put something in the NVR I have to use:

# define COMM_NVR __attribute__((section(".common_nvr")))

// example of putting variable in NVR.

unsigned char fred COMMON_NVR;

When I want to access fred from another file I have to:

extern unsigned char fred COMMON_NVR;

If I forget to add the COMMON_NVR attribute then I get the linker error you describe, 'Can't reach....'.

So maybe your unreachable variable isn't where you think it is.

Banx.
