Part Number: TMS320F28075

Tool/software: TI C/C++ Compiler

Hi Sir,

After compiler I have 92 warnings, those are the same category.

Description Resource Path Location Type
#10247-D creating output section "AdcaRegsFile" without a SECTIONS specification YDelta_LLC    C/C++ Problem

Description Resource Path Location Type
#10247-D creating output section "AdcaResultFile" without a SECTIONS specification YDelta_LLC    C/C++ Problem

etc....

On the .map file have define:

AdcaRegsFile
*          1    0000bf80    00000080     UNINITIALIZED
                  0000bf80    00000080     F2807x_GlobalVariableDefs.obj (AdcaRegsFile)

AdcaResultFile
*          1    0000cb24    00000018     UNINITIALIZED
                  0000cb24    00000018     F2807x_GlobalVariableDefs.obj (AdcaResultFile)

etc....

What should I check somewhere? Or I loss something?

Would you give me some ideal, please thank you.

If more information please feel free to let me know,

BR

    I suspect this may be because you do not have F2807x_Headers_nonBIOS.cmd or F2807x_Headers_BIOS.cmd in your project

    Hi Sir,

    I think there is the root couse.

    but I have some questions would you help me?

    1. What's diffreent between F28xx_Headers_BIOS.cmd & F28xx_Headers_nonBIOS.cmd

    2. In the CCS project should be only one .cmd active right?

        Why some of projcets have include over two .cmd?

        How to know which one .cmd file is active for current projcet?

    You can have two .cmd files in a project.  The _BIOS or _nonBIOS cmd file defines the peripheral registers while the other .cmd file maps sections of memory and code.


    The _BIOS cmd file is for DSP/BIOS and SYS/BIOS projects with an RTOS and does not have the PIE vector.
    The _nonBIOS cmd file is for other projects and has the PIE vector table.
