CRC_TABLE value in flash not math to value in map & xml file

Hello!

I want math map file with firmware version. I add crc_table keyword to linker cmd file. crc_table in memory contains crc_value field. This field contains 64 bit value.  .map file & xml.file contains 32bit value.  Where is error? 

===============C code=======
extern CRC_TABLE crc_table;

uint64_t get_flash_crc(void) {
    uint64_t i;
    uint64_t res = 0;
    for (i = 0; i < crc_table.num_recs; i++) {
        uint64_t val=crc_table.recs [i].crc_value;
//        res ^= val;
        printf("crc_val=0x%016llX\r\n", val);
    }
    return res;
}

=============C code output======

crc_val=0x19F7FE3ECAD7EC6C
crc_val=0xE1EA649C3D1C4B81
crc_val=0xFAE17A96B265E31C
crc_val=0x00743C1800000000
crc_val=0x81E7E980829E2267
crc_val=0xDD2252DE85854DB9
crc_val=0x97D8C51F44450053

    The map file and XML file are in error. 

    Do you use the TI ARM compiler?  What version?  For right now I presume you use TI ARM compiler version 5.2.5.

    The CRC value is 64-bits.  You can see this in the include file crc_tbl.h, which is in the /include directory of the compiler installation.

    /*********************************************************/
/* CRC Record Data Structure                             */
/* NOTE: The list of fields and the size of each field   */
/*       varies by target and memory model.              */
/*********************************************************/
typedef struct crc_record
{
uint64_t         crc_value;
uint32_t         crc_alg_ID;    /* CRC algorithm ID */
uint32_t         addr;          /* Starting address      */
uint32_t         size;          /* size of data in bytes */
uint32_t         padding;       /* explicit padding so layout is the same */ 
                                /* for COFF and ELF                       */
} CRC_RECORD;

 
/*********************************************************/
/* CRC Table Data Structure                              */
/*********************************************************/
typedef struct crc_table
{
uint32_t         rec_size;
uint32_t         num_recs;
CRC_RECORD       recs[1];
} CRC_TABLE;

    I think I can reproduce this bug on my own.  If not, I may ask you for a test case.  Once I have reproduced the error, I'll submit a bug report and let you know the ID number.

    Thanks and regards,

    -George

    CRC_Test.zipHello!

    I use TI ARM Compiler 5.2.6. Same problem with 5.2.4. My target platform TMS570. You can found very simple sample in attachment

    Thank you for reporting this problem.  I can reproduce the same results.  I filed SDSCM00052430 in the SDOWP system to have this investigated.  You are welcome to follow it with the SDOWP link below in my signature.

    Thanks and regards,
