Renaming linker cmd file generated a linker warning

Other Parts Discussed in Thread: CONTROLSUITE

Hi TI CCS gurus,

I have a simple C28 project derived from flash programming example. It builds and runs fine without any issue or warning. However, after I simply renamed the linker cmd file from its default name (2837xD_xxx.cmd) to anything different (e.g. xxx.cmd), I'd get a warning from linker: 

#1068-D no matching section.

IF I name it back, the warning would be gone. I tried it back and forth several times, always saw the issue. I tried renaming it inside CCS project explorer and Windows explorer, no difference.  I'd like to use a different name, but more curious why the same cmd file would product different results depending on names? Does CCS treat cmd file named as "C2837xD_xxx" differently or what? I'd appreciate any advise. Thanks!

    Hi Shef,
    How is the .cmd file being referenced? Is it physically added to the project or is it referenced in the project properties (linker setting)?

    Thanks

    Thanks for replying promptly! The cmd file is physically added/ located in the project folder. It used to be in the linker property settings pointing to controlSuite. I removed it and copied the cmd file to the project folder so that I can freely modify it. It has been modified many times in local folder and works fine. But after I tried to rename it, it gives me a warning, although seems to still working. Any idea why?

    Can you attach the project? At the very least I'd like to see the project metadata file (.*project files)

    Thanks

    Hi Ki,
    I sent you my project file via email a week ago. Did you receive it, and is anything looking into this issue? Please advise if there is any update. Thanks!

    Hi Shef,
    Sorry for the delay. I missed your e-mail. I checked my inbox again and found it. I imported it and am trying to build it. I get a bunch of linker errors because 2837xD_RAM_lnk_cpu1_USB.cmd and 2837xD_SBLapp_cpu1.cmd define the same memory regions. Are both supposed to be part of the build?

    Thanks

    Hi Ki,
    I just replied you via a detailed email. This project runs in flash therefore should set to flash configuration, not using RAM cmd file. I wonder why it went to RAM config though.
