i use 9s12xep100 . in DFLASH area i defined a const variable, but in S19 file, there is no record about this const variable.

hi !

prm file like this

SEGMENTS

      EEPROM_00     = READ_ONLY   DATA_FAR IBCC_FAR 0x000800 TO 0x000BFF;
      EEPROM_01     = READ_ONLY   DATA_FAR IBCC_FAR 0x010800 TO 0x010BFF;
      EEPROM_02     = READ_ONLY   DATA_FAR IBCC_FAR 0x020800 TO 0x020BFF;

END

PLACEMENT

CALI_DATA INTO EEPROM_01;

END

main file like this

#pragma DATA_SEG __GPAGE_SEG CALI_DATA

volatile const unsigned int test[3] = {1 , 3 , 4};

#pragma DATA_SEG DEFAULT

void main(void) {
/* put your own code here */

unsigned int a_test = test[0];
unsigned char cnt;

for(cnt=0;cnt<3;cnt++)
{
    a_test = test[cnt];
    a_test++;
}


for(;;)
   {
      a_test++;

}
}

i use codewarrior compile this project , and in MAP file i checked that

- VARIABLES:
test 10800 6 6 4 CALI_DATA

bus the s19 file has no record about "test" variable

S123C000CF2100C6055B134A802CFE4A8000FE0000C015C051000000000000000000000051

S219FE804026F2FEC013EC31270BED31180A30700434F920F10AC4
S9030000FC

my question is: why there is no record information about DFLASH const variable "test" in s19 file.1

thanks all！

Hello

No EEPROM content shown in S19 file is because the burner.bbl missed non-banked EEPROM. I did the modification in burner.bbl for you, see attached.

/* logical non banked EEPROM at $0C00 to logical */
len = 0x400
origin = 0x000C00
destination = 0x000C00
SENDBYTE 1 "%ABS_FILE%"

/* logical non banked EEPROM at $0800 to logical */
len = 0x100
origin = 0x000800
destination = 0x000800
SENDBYTE 1 "%ABS_FILE%"

/* logical non banked EEPROM at $0C00 to global */
len = 0x400
destination = 0x13FC00
origin = 0x000C00
SENDBYTE 1 "%ABS_FILE%"

/* logical non banked EEPROM at $0800 to global */
len = 0x100
destination = 0x100000
origin = 0x000800
SENDBYTE 1 "%ABS_FILE%"

With the new bbl file, compile the C sample code, you can see this line added in s19 file:

S11208001245486F772061726520796F7521006A

I will also attach my demo project.

Have a great day,
Jennie Zhang
