CCS/TMS320F28069: Warning : #10068-D no matching section for Flash2806x_API_wFPU_Library.lib

Part Number: TMS320F28069
Other Parts Discussed in Thread: CONTROLSUITE

Tool/software: Code Composer Studio

Hi,

When I try to put library Flash2806x_API_wFPU_Library.lib into the RAM receive warning message that not matching section

Used Code Composer Studio Version: 6.1.3.00033, compiler version TI v15.12.1.LTS

Library getting from controlSUITE

In linker file added following lines:

   Flash28_API: // Applicable only when API is not in BootROM
  {
   		-l Flash2806x_API_wFPU_Library.lib (.econst)
        -l Flash2806x_API_wFPU_Library.lib (.text)
   }
					LOAD = FLASHD
					RUN = RAML0
					LOAD_START(_Flash28_API_LoadStart),
					LOAD_END(_Flash28_API_LoadEnd),
					RUN_START(_Flash28_API_RunStart),
					PAGE = 0

Also getting from examples in controlSUITE.

What I do wrong?

    Alex,

    Have you actually called an API function?  If you don't call a function in the library, nothing from the library gets pulled into the project and hence you get the no matching section warning.

    Regards,

    David

    I use these functions from library:
    Flash_Program()
    Flash_Erase()

    The no matching sections found warning occurs when you specify special linkage of a section in the .cmd file but that section is not in the project. Hence, I suspected that either the .econst and/or the .text section from the API library is not present in your project.

    Check the .map file and see if these sections have been pulled in. The diagnostic about no matching section is just a warning, so the build should complete anyway.

    Regards,
    David

    I do not see .econst or .text contributions from the Flash2806x_API_wFPU_Library.lib in your listing. Are you certain that you call Flash_Program() and Flash_Erase()? I still suspect that you are not calling any functions that are in the API library.

    Hi David,

    Thank you for help, I found some mistakes in our code and now library loaded correctly.

    But now I have another issue with making the correct hex file of firmware.

    By default when I choose intel format hex2000 generates two output files, they looked like one contains lower bytes and another one high bytes.

    If I choose option --image in general option of C2000 hex utility of property tab, I receive an error message:

    Description Resource Path Location Type
    -image requires ROMS directive PSC_BMS_CAN C/C++ Problem

    So, how to solve this issue?

    Hi, can you share what kind of mistakes you found in your code to fix that linker issue? I'm running into something that looks very similar and would like to be doing something else entirely. Thanks!
