CCS/CC2640R2F: unresolved symbol ramEndHere, first referenced in <whole-program>

Part Number: CC2640R2F

Tool/software: Code Composer Studio

I am using the OAD off chip for the launchpad. I imported the projects and after getting it to compile I am getting :

unresolved symbol ramEndHere, first referenced in <whole-program>

unresolved symbol startup_entry, first referenced in <whole-program>

Both it seems should be generated by the Linker command file/configuration. I see ramEndHere referenced in the stack project, but it is not being created by the app project.

I am using the regulear blestack not ble5stack. I could guess the right value and hard code it, but that seems dangerous. What is the fix?

Hi Greg,

Thanks for letting me know.

Try uninstalling and reinstalling CCS again and see if that solves the problem.

Thanks,
Elin

Hi Greg,

Thanks for checking.

I just tested importing simple_peripheral_oad_offchip in CCS 9.3 and didn't get any errors when building the projects so the issue might be related to your build environment.

Can you build other projects from the SDK?

Thanks,
Elin

So I believe I have resolved the issue. The procedure that I used was to copy the example from the 2640 SDK to my local directory, and import from my local directory which left a bunch of files missing when I imported from my local copy. I instead imported directly from the SDK directory and now it imported correctly. It is strange that even when I resolved all the missing files and added links to the missing files, it still gets this error. Can you explain what this error?

Hi Greg,

I'm no CCS expert but I believe that a lot of the paths are relative to the import directory. So if the files aren't where CCS expects them to be, it cannot find them.

Thanks,
Elin
