Boolean problem on Launchpad F28377S

Other Parts Discussed in Thread: CONTROLSUITE, TMS320F28377S

I've been struggling for the whole day trying to compile a very simple (and empty) program on the Launchpad F28377S.

It fails complaining that the _Bool type is undefined:

"C:/ti/ccsv6/tools/compiler/ti-cgt-c2000_6.4.10/bin/cl2000" -v28 -ml -mt --cla_support=cla1 --float_support=fpu32 --tmu_support=tmu0 --vcu_support=vcu2 -O2 --include_path="C:/ti/ccsv6/tools/compiler/ti-cgt-c2000_6.4.10/include" --include_path="C:/ti/controlSUITE/device_support/f2837xD/v110/F2837xD_headers/include" --include_path="C:/ti/controlSUITE/device_support/f2837xD/v110/F2837xD_common/include" --advice:performance=all -g --c++03 --cpp_default --define=_INLINE --define=CPU1 --diag_warning=225 --display_error_number --diag_wrap=off --preproc_with_compile --preproc_dependency="main.pp"  "../main.cpp"
"C:/ti/controlSUITE/device_support/f2837xD/v110/F2837xD_headers/include/F2837xD_Device.h", line 102: error #20: identifier "_Bool" is undefined
"C:/ti/controlSUITE/device_support/f2837xD/v110/F2837xD_headers/include/F2837xD_Device.h", line 105: error #20: identifier "_Bool" is undefined
"C:\ti\controlSUITE\device_support\f2837xD\v110\F2837xD_common\include\F2837xD_Pbist_defines.h", line 252: error #20: identifier "_Bool" is undefined
"C:\ti\controlSUITE\device_support\f2837xD\v110\F2837xD_common\include\F2837xD_Pbist_defines.h", line 254: error #20: identifier "_Bool" is undefined

If the project is compiled in C instead of C++ (thus the main is included in a main.c file rather than a main.cpp file) the project compiles correctly. Now I do need C++ for development of my project so I would like to hear what could solve this. I tried the workarounds of editing the controlSUITE libraries and declare or typedef _Bool but got nowhere.

Ironically I can compile my project if I link it against other Piccolos' libraries but that's not the point. The point is to use this powerful hardware to its full extent ;)

Anyone got this sorted? 

Thanks

    Technically, there is no formal solution for this problem. The type _Bool only exists in the standard C language. The C++ language does not provide any type that would guarantee compatibility with _Bool. Now you could try using #include <stdbool.h> and use bool. However this is not guaranteed to be compatible. The best recommendation would be working strictly in C, but I guess I can see the possibility of using C++ in order to take advantage of certain programming capabilities. Try using the workarounds and if not, the best suggestion would be reverting your code to C99.

    Hi Kyle,

    My main is actually empty ...

    /*
    * main.cpp
    *
    * Created on: 6-mag-2016
    * Author: Stefano
    */

    #include "F28x_Project.h" // Device Headerfile and Examples Include File
    #include <limits.h>
    #include <stdio.h>

    int main()
    {

    return 0;
    }

    It is just the "F28x_Project.h" that seems to mess up the booleans thing ...

    I'm trying to update TI ControlSUITE to latest version that includes support for F2833xS. I am now using the libs and headers for F2833xD which may explain this problem. I'll keep you updated ;)

    Please do. Getting any feedback is greatly appreciated and hopefully will be helpful in fixing this problem.

    OK so this is what I did, following and adapting the guide in e2e.ti.com/.../1541.Lunchpad-basics.pdf

    1) Update ControlSUITE to latest version. In the old version I had installed there was support for F2837xD but not F2837xS. Indeed the F28377S launchpad didn't appear in the device search results

    2) Manually added in F2837xS_device.h (TI: could you please fix this upstream ?)

    #ifdef __cplusplus
    typedef bool _Bool;
    #endif

    Just after the existing #include <stdint.h>

    3) Project properties -> CCS Build -> C2000 Compiler -> Advanced options -> Language options and
    unchecked the "Treat C files as C++ files (--cpp_default, -fg)" option (I think I set this myself though)

    4) Resource -> Linked Resources -> Path Variables
    Click "New" and create a variable "CONTROLSUITE" pointing to "C:\ti\controlSUITE"

    5) Project properties -> CCS Build -> C2000 Compiler -> Include options
    Add "${CONTROLSUITE}/device_support/f2837xS/v191/F2837xS_headers/include"
    Add "${CONTROLSUITE}/device_support/f2837xS/v191/F2837xS_common/include"

    6) Project properties -> CCS Build -> C2000 Linker -> File Search Path
    Add "${CONTROLSUITE}/device_support/f2837xS/v191/F2837xS_common/include"

    7) Go with Windows explorer to C:\ti\controlSUITE\device_support\F2837xS\v191\F2837xS_common\source and drag and drop the following files to CCS project:
    - F2837xS_CodeStartBranch.asm
    - F2837xS_CpuTimers.c
    - F2837xS_DefaultISR.c
    - F2837xS_Gpio.c
    - F2837xS_PieCtrl.c
    - F2837xS_PieVect.c
    - F2837xS_SysCtrl.c
    - F2837xS_usDelay.asm

    Be sure to select "Link files" and relative to "CONTROLSUITE" in the dropdown menu

    8) Go with Windows explorer to C:\ti\controlSUITE\device_support\F2837xS\v191\F2837xS_headers\source and drag and drop the following files to CCS project:
    - F2837xS_GlobalVariableDefs.c

    Be sure to select "Link files" and relative to "CONTROLSUITE" in the dropdown menu

    9) Go with Windows explorer to C:\ti\controlSUITE\device_support\F2837xS\v191\F2837xS_headers\cmd and drag and drop the following files to CCS project:
    - F2837xS_Headers_nonBIOS.cmd

    Be sure to select "Link files" and relative to "CONTROLSUITE" in the dropdown menu

    10) Go with Windows explorer to C:\ti\controlSUITE\device_support\F2837xS\v191\F2837xS_common\cmd and drag and drop the following files to CCS project:
    - 2837xS_Generic_FLASH_lnk.cmd

    Be sure to select "Link files" and relative to "CONTROLSUITE" in the dropdown menu

    11) Project properties -> CCS General
    Family: C2000
    Variant: TMS320F28377S
    Connection: Texas Instruments XDS100v2 USB Debug Probe

    Compiler version: TI v6.4.10
    Linker command file: F2837xS_Headers_nonBIOS.cmd
    Runtime support library: <automatic>


    ** Be sure to link the "2837xS_Generic_FLASH_lnk.cmd" file (step 10) otherwise you will get many errors for many sections not fitting into memory **


    Like this I am able to compile and upload a basic (and empty) program into the Launchpad.
    I hope this information can be useful to those in a similar situation.

    Just another question: is it possible to avoid erasing the RAM at each time I upload a new program ? I am a bit worried of wearing it out quickly (and it takes quite a few seconds to do it) ? Maybe I should replace the 2837xS_Generic_FLASH_lnk.cmd with the 2837xS_Generic_RAM_lnk.cmd ?
