TMS570LS0432: why link generate CRC value compare the SL_CRC_Calculate is different？

Hello 

 Team

my cmd

SECTIONS
{
.intvecs : START( ulFlashStartAddr ) {} > VECTORS
.text : {}palign=8, crc_table(_my_crc_table, algorithm=TMS570_CRC64_ISO) > FLASH0
.TI.crctab : {} palign=8 > FLASH0 /* The CRC tables generated by the linker are created in the special section .TI.crctab */
.const : END( ulFlashEndAddr )
{} > FLASH0
.cinit : {} > FLASH0
.pinit : {} > FLASH0
.STACK_DATA_svc : {. += 10240;} > STACKS, RUN_START(StackModeSVC)

.bss : {} > RAM
.data : {} > RAM
.sysmem : {} > RAM

LOG_DATA : START( ulLOGStartAddr ), END( ulLOGEndAddr ) > LOG
PROFILE_DATA : START( ulPROFILEStartAddr ), END( ulPROFILEEndAddr ) > PROFILE
}

link generate the crc value is different my

 SL_CRC_Calculate((uint64 *)((uint32)&ulFlashStartAddr), ((((uint32)&ulFlashEndAddr)-((uint32)&ulFlashStartAddr)) >> 6))

what reason ？How to modify？

  Thank you
