_FAR_COPY_RC undefined

deneb — Wed, 08 Jul 2009 20:01:37 GMT

Hello

I am trying to initialize a variable from a constant located in rom. When I make, I get the following linker error:

Link Error : L1822: Symbol _FAR_COPY_RC in file C:\Proj1\Proj1_Data\Proj1\ObjectCode\main.c.o is undefined Link Error : Link failed

It is CodeWarrior 4.7 for HCS12.

Does someone know why I am having this error?

Thanks

deneb

Hi daneb,

_FAR_COPY_RC runtime routine is part of "datapage.c" and it is responsible for accessing data in paged memory. I'd suggest you to check if the file "datapage.c" is available (and enabled...if you use more build targets) in your project.

Hello Stanish

Thanks for your reply.

However, I just solved the problem myself. The project that I have been working on, I took it over from one of my colleagues. Strangely, the _FAR_COPY_RC was chopped away from the datapage.c. So I copied the appropriate code from C:\Freescale\CodeWarrior for HCS12 V4.7\lib\hc12c\sr\datapage.c and it worked.

Best regards,

deneb
