Compiler/TMS320F280049C: TMS320F280049C FlashApi using

Part Number: TMS320F280049C
Other Parts Discussed in Thread: C2000WARE

Tool/software: TI C/C++ Compiler

Hello!
      The following problems were encountered when using the FlashApi of TMS320F280049C:

1. warning 28004x_generic_flash_lnk.cmd", line 282: warning #10068-D: no matching section

2. The FlashApi library file could not be found when linking:

undefined first referenced  symbol in file      

Fapi_checkFsmForReady() 
Fapi_doBlankCheck(unsigned long *, unsigned long, Fapi_FlashStatusWordType *) 
Fapi_doVerify(unsigned long *, unsigned long, unsigned long *, Fapi_FlashStatusWordType *) 
Fapi_getFsmStatus() 
Fapi_initializeAPI(volatile FMC_REGISTERS *, unsigned long) 
Fapi_issueAsyncCommandWithAddress(Fapi_FlashStateCommandsType, unsigned long *) 
Fapi_issueProgrammingCommand(unsigned long *, unsigned int *, unsigned int, unsigned int *, unsigned int, Fapi_FlashProgrammingCommandsType) 
Fapi_setActiveFlashBank(Fapi_FlashBankType)

But actually I have included the corresponding header files and libraries.

The corresponding configuration in the cmd file is as follows:

PAGE 0 :
 ......

RAMGS1 : origin = 0x00E000, length = 0x002000

RAMGS2 : origin = 0x010000, length = 0x002000

RAMGS3 : origin = 0x012000, length = 0x002000

/* Flash sectors */
FLASHA : origin = 0x080002, length = 0x001FFE /* on-chip Flash */
FLASHB : origin = 0x082000, length = 0x002000 /* on-chip Flash */
......

Flash28_API:

//-l F021_ROM_API_F28004x_FPU32.lib

    Hi,

    Could you please use the project

    "flashapi_ex1_program_autoecc" from \C2000Ware_1_00_06_00\driverlib\f28004x\examples\flash\
    Or use this project as reference for modifying your project.

    Include options and linker options can be referred from here.
    Regarding the warning, use 28004x_flash_api_lnk.cmd linker command file.

    Please let me know if you need anything else.

    Thanks,
    Katta

    Zhaoheng,

    The linker command file (28004x_flash_api_lnk.cmd) used with Flash API usage example (flashapi_ex1_program_autoecc) is available at C:\ti\c2000\C2000Ware_x_xx_xx_xx\device_support\f28004x\common\cmd.

    Also, the Flash API library is available at \C2000Ware_x_xx_xx_xx\libraries\flash_api\f28004x\lib.
    Please check the path you are using.

    Thanks and regards,
    Vamsi

    Compare flashapi_ex1_program_autoecc and found the following differences：
    My cmd is：
    .TI.ramfunc : LOAD = FLASHCH,
    RUN = RAMGS1,
    LOAD_START(_RamfuncsLoadStart),
    LOAD_SIZE(_RamfuncsLoadSize),
    LOAD_END(_RamfuncsLoadEnd),
    RUN_START(_RamfuncsRunStart),
    RUN_SIZE(_RamfuncsRunSize),
    RUN_END(_RamfuncsRunEnd),
    PAGE = 0, ALIGN(4)
    Flash28_API:
    {
    -l F021_API_F28004x_FPU32.lib
    }
    LOAD = FLASHB,
    RUN = RAMGS3,
    LOAD_START(_Flash28_API_LoadStart),
    LOAD_SIZE(_Flash28_API_LoadSize),
    LOAD_END(_Flash28_API_LoadEnd),
    RUN_START(_Flash28_API_RunStart),
    RUN_SIZE(_Flash28_API_RunSize),
    RUN_END(_Flash28_API_RunEnd),
    PAGE = 0
    flashapi_ex1_program_autoecc‘s cmd is：
    GROUP
    {
    .TI.ramfunc
    { -l F021_API_F28004x_FPU32.lib}

    } LOAD = FLASH_BANK0_SEC1,
    RUN = RAMLS03,
    LOAD_START(_RamfuncsLoadStart),
    LOAD_SIZE(_RamfuncsLoadSize),
    LOAD_END(_RamfuncsLoadEnd),
    RUN_START(_RamfuncsRunStart),
    RUN_SIZE(_RamfuncsRunSize),
    RUN_END(_RamfuncsRunEnd),
    PAGE = 0, ALIGN(4)

    Hi,

    Could you compile the code without any build errors?

    Looks like you are storing Flash API ramfuncs and .TI.ramfuncs in different sectors.

    Do you have Flash28_API_LoadStart, Flash28_API_LoadEnd etc. declared somewhere?

    Did you do a memcpy with above variables similar to
    memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize);

    Does RAMGS3 belong to PAGE 0?

    Please let us know your current issue.

    Thanks,
    Katta

    Thanks for your reply!

    Could you compile the code without any build errors?
    No, compile stage have no error, linker stage have error: undefined first referenced symbol in file Fapi_checkFsmForReady() etc.

    Looks like you are storing Flash API ramfuncs and .TI.ramfuncs in different sectors.
    yes, I did storing Flash API ramfuncs and .TI.ramfuncs in different sectors.

    Do you have Flash28_API_LoadStart, Flash28_API_LoadEnd etc. declared somewhere?
    I have not declared Flash28_API_LoadStart, Flash28_API_LoadEnd somewhere, only in .cmd;
    In my program, just extern them.

    Did you do a memcpy with above variables similar to
    Yes, I do memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize); in my program.

    Does RAMGS3 belong to PAGE 0?
    Yes, RAMGS3 belong to PAGE 0.

    Hi,

    Do you have  memcpy(&Flash28_API_RunStart, &Flash28_API_LoadStart, (size_t)&Flash28_API_LoadSize); used in the code.

    Could you please share your compiler settings?

    Did you update your linker file search path to C2000Ware_x_xx_xx_xx\libraries\flash_api\f28004x\lib
    from workspace_loc:/${ProjName}/Driver/common/lib?

    Thanks,
    Katta

    Thank you very much for your reply!
    The problem has been solved, due to the mixed compilation of C and C++.
