TMS320F28027: Error: Memory Map prevented

Part Number: TMS320F28027


Tool/software:

Hello team, 

We attempted to extend the memory of PRAML0 by increasing its allocated size to accommodate more variables. To achieve this, we reduced the size of DRAML0 accordingly. After making these changes, the code was able to compile successfully, and the previous compilation error was resolved.

However, after flashing the code to the target, we encountered a "memory map prevented" issue. Specifically, the variables that were intended to use the newly allocated region in PRAML0 (taken from DRAML0) could not be accessed at runtime. This memory reallocation allowed successful compilation, the re-mapped area from DRAML0 is not accessible or usable at runtime, leading to the error.
