[FAQ] F05 Flash: What does the "initialized RAM warning" from the code composer plug-in mean?

Q: When programming the flash with Code Composer Studio, I get a warning regarding initialized RAM.  What does this warning mean?

  • A:

    Note: This answer applies to devices with F05 flash.  Refer to:  [FAQ] F05 Flash: Which C2000 devices have "F05 flash"?

    This means that there is an initialized section that is assigned to the RAM area. This will work fine while the power and JTAG is connected but once power is removed, RAM data is lost which will prevent proper execution when executing standalone. The linker .cmd file needs to be checked to ensure that all initialized sections are assigned to flash.

    This message may indicate at least one section designated to LOAD to flash but RUN from RAM in your .cmd file (which is normal for a proper flash setup). The warning is normal, and can be safely ignored as long as all initialized sections have been verified to be allocated to flash mentioned above. DSP/BIOS projects will generate this warning as well due to a couple of data sections being assigned to the RAM. In this case the message can be ignored as well.
