CCS/TMS570LC4357: FLASH API Problem: Undefined Symbols

Xiangguang feng

Part Number: TMS570LC4357

Tool/software: Code Composer Studio

I'm try to develop FLASH API functions with the example given in SPNA148. I copied the example code and included the directory for F021.h. When I try to compile the function it says:

undefined first referenced
symbol in file
--------- ----------------
Fapi_initializeFlashBanks ./source/HL_sys_main.obj
Fapi_setActiveFlashBank ./source/HL_sys_main.obj

Is there any header or source code I should include to resolve the problem?

Hello,

You should add F021 Library files to CCS Project

Add/Link F021_API_CortexR4_BE_L2FMC_V3D16.lib from folder C:/ti/Hercules/F021 Flash API/2.01.01 to CCS Project
Add Path C:/ti/Hercules/F021 Flash API/2.01.01/include to Include Path in CCS Project

Best regards,
Miro

Hi Miro,

I did what you say and the error is gone. however now there is new error:

"../source/HL_sys_main.c", line 87: error #137: struct "<unnamed>" has no field "Busy"
"../source/HL_sys_main.c", line 114: error #137: struct "<unnamed>" has no field "Busy"

which points to this line:

if((oReturnCheck == Fapi_Status_Success) &&
(FLASH_CONTROL_REGISTER->FmStat.FMSTAT_BITS.Busy != Fapi_Status_FsmBusy)){

... ...

}

I copied all these codes and don't know how to fix the error.

Hello,

Please, verify you have added "C:/ti/Hercules/F021 Flash API/2.01.01/" dir in CCS Build->ARM Compiler->Include options:

Note: Your installation folder could be different from the one in the screenshot.

I verified and the directory is indeed in the include option as shown.
