TMS320F28388D: Query: Troubleshooting Macro Redefinition and Path Variable Replacement Issues in CCS Project

Part Number: TMS320F28388D

Tool/software:

I have a couple of doubts regarding my CCS project:

  1. Macro Redefinition Error: When building my CCS project, I encountered a failure stating that a macro is already defined, even though I am defining it myself.

  2. Path Variable Replacement Issue: My custom-defined macro paths are being automatically replaced with built-in paths. Specifically, I have defined the macro as follows:

    <pathVariable name="C2000WARE_DIR" path="C:\ti\c2000\C2845D~1\" scope="project" />

    However, it is being replaced with ${TI_PRODUCTS_DIR_TIREX}\c2000\C2845D~1, which is unexplained and causes errors during file linking

    Linker resources Tab Macro Value in Path Variables

can you please give me the reasoning behind these two issues?

1. What can trigger this macro re-definition error
2. Why is this path being replaced, and how can I fix this?
