TMS570LS0232: Fapi_serviceWatchdogTimer linker error while using Fapi_doMarginReadByByte function

Hi everyone,

I was trying to compile TI bootloader for TMS570LS0232, I have got a linker error while using Fapi_doMarginReadByByte function.

undefined                 first referenced                                                                       
  symbol                       in file

 Fapi_serviceWatchdogTimer C:\ti\Hercules\F021 Flash API\02.01.01\F021_API_CortexR4_BE_NDS.lib<Read.WdService.obj>

I research about using FAPI version 02.01.01 for TMS570LS0232 but nothing about any restriction for this MCU.

When I delete code block about FAPI reading, It's compiled successfully.

uint32_t Fapi_BlockRead( uint32_t Flash_Start_Address, uint32_t Data_Start_Address, uint32_t Size_In_Bytes)
{
	register uint32_t src = Data_Start_Address;
	register uint32_t dst = Flash_Start_Address;
	register uint32_t bytes_remain = Size_In_Bytes;
	int bytes;

	if (Size_In_Bytes < 16)
		bytes = Size_In_Bytes;
	else
		bytes = 16;

 	while( bytes_remain > 0)
	{
		Fapi_doMarginReadByByte((uint8_t *)src,
								(uint8_t *)dst,
								(uint32_t) bytes,                //16
								Fapi_NormalRead);
		src += bytes;
		dst += bytes;
        bytes_remain -= bytes;
    }
	return (0);
}
