Not Able to partition for MK40DX256VLQ10

[see]

I am facing problem with partition before programing on MCU, a flash program is used to mass erase the mcu.

emulator used: PE universal multilink

below are my codes.

#define LONGWORD_COUNTER_ADDR 0x14000000

#define WORD_COUNTER_ADDR 0x14000004

#define BYTE_COUNTER_ADDR 0x14000006

#define EEPROM_16_16 0x39     // subsystem A = 16 bytes, subsystem B = 16 bytes #define DFLASH_SIZE_128 0x05

          /* Partition the memory to enable FlexMem mode *   

        if ( partition_flash( EEPROM_16_16, DFLASH_SIZE_128) )

           {

               /* Device has been partitioned for the first time, so this

                * means the counters have not been initialized yet. We'll

                * zero them out now.

                */

              //printf("\nVariables on FlexRAM are initialized to 0x11111111, 0x2222, and 0x33!\n");

*((uint32 *)(LONGWORD_COUNTER_ADDR)) = 0x11111111;

               /* Wait for the command to complete */

               while(!(FTFL_FCNFG & FTFL_FCNFG_EEERDY_MASK));

               *((uint16 *)(WORD_COUNTER_ADDR)) = 0x2222;

               /* Wait for the command to complete */

               while(!(FTFL_FCNFG & FTFL_FCNFG_EEERDY_MASK));

               *((uint8 *)(BYTE_COUNTER_ADDR)) = 0x33;

               /* Wait for the command to complete */

               while(!(FTFL_FCNFG & FTFL_FCNFG_EEERDY_MASK));    

           }

           else

           {

              //printf("\nDevice already partitioned\n");

              /* Change the value of BYTE variable to 0x88 */

              *((uint8 *)(BYTE_COUNTER_ADDR)) = 0x33;

              /* Wait for the command to complete */

              while(!(FTFL_FCNFG & FTFL_FCNFG_EEERDY_MASK));  

}

              /* Read the variables from FlexRAM */

int RAMFUNC  partition_flash(int eeprom_size, int dflash_size)

{

/* Test to make sure the device is not already partitioned. If it

       * is already partitioned, then return with no action performed.

       */

.

       if ((SIM_FCFG1 & SIM_FCFG1_DEPART(0xF)) != 0x00000F00)

{

// printf("\nDevice is already partitioned.\n");

          return 0;

}

/* Write the FCCOB registers */

           /* clear RDCOLERR & ACCERR & FPVIOL flag in flash status register */

           FTFL_FSTAT = (0x40|0x20|0x10);

FTFL_FCCOB0 = 0x80;// Selects the PGMPART command

FTFL_FCCOB1 = 0x00;

FTFL_FCCOB2 = 0x00;

FTFL_FCCOB3 = 0x00;

/* FCCOB4 is written with the code for the subsystem sizes (eeprom_size define) */

FTFL_FCCOB4 = eeprom_size;

/* FFCOB5 is written with the code for the Dflash size (dflash_size define) */

FTFL_FCCOB5 = dflash_size;

/* All required FCCOBx registers are written, so launch the command */

FTFL_FSTAT = FTFL_FSTAT_CCIF_MASK;

/* Wait for the command to complete */

while(!(FTFL_FSTAT & FTFL_FSTAT_CCIF_MASK));

return 1;

}

At Linker file

/* Specify the memory areas */

MEMORY

{

m_interrupts       (rx) : ORIGIN = 0x00000000, LENGTH = 0x1E0      /* Loo: rx--> r: read  x : execute */

m_cfmprotrom       (rx) : ORIGIN = 0x00000400, LENGTH = 0x10

m_text             (rx) : ORIGIN = 0x00000800, LENGTH = 256K - 0x800

m_data         (rwx) : ORIGIN = 0x1FFF8000, LENGTH = 32K                  /*  Lower SRAM r: read, w:write, x: execute  */

m_data2        (rwx) : ORIGIN = 0x20000000, LENGTH = 32K                  /* Upper SRAM */

}

/* Define output sections */

SECTIONS

{

.data : AT(___ROM_AT) /*contents of .data is going to be placed in the flash address pointed by _ROM_AT*/

{

. = ALIGN(4);

_sdata = .;        /* create a global symbol at data start */

*(.data)           /* .data sections */

*(.data*)          /* .data* sections */

       *(.ramsection) /* here your ramsection will be located */

. = ALIGN(4);

*(.relocate_code)

       . = ALIGN(4);

_edata = .;        /* define a global symbol at data end */

} > m_data  /* The content of this .data is going to be placed in memory segment m_data or Lower RAM */

}

additional information:

SIM_FCFG1 always show 0xff020e00 upon run debug

FTFL_FCNG = 0x02, FTFL_FSTAT = 0x80 and EEERDY bit never set

I would recommend customer to download Kinetis Flash driver software from below link, which includes FlexNVM partition example demo (demo_normal).

C90TFS_FLASH_DRIVER(TFS Flash Driver Software for Kinetis and ColdFire+ Microcontrollers):

http://cache.freescale.com/files/32bit/software/C90TFS_FLASH_DRIVER.exe

Wish it help.

I  manage to solve the problem by migrating the project from CW10.4 to CW 10.6. thanks
