9S08PA60 in CW MCU 10.4/10.6, Processor Expert generated intFlash Code Fail

[BillQu]

Hi all,

My MCU is 9S08PA60, use PE to generate a Flash component,

below is IFsh.c

typedef struct {

   uint8_t code[12];             /* Structure required to copy code to ram memory */

  /* Size of this structure needs to be at least (but best) the size of the FnCmdInRam_ */

} FnCmdInRamStruct;

typedef void (* near pFnCmdInRam)(void);

/* Global variables */

static void FnCmdInRam_(void)

{

  NVM_FSTAT = 0x80U;                   /* Clear flag command buffer empty */

  while (NVM_FSTAT_CCIF == 0U) {}      /* Wait to command complete */

  return;

}

#pragma MESSAGE DISABLE C1805          /* Disable warning C1805 "Non-standard conversion used" */

/*lint -save  -e740 -e931 Disable MISRA rule (1.2) checking. */

static void CallFnCmdInRam()

{

  FnCmdInRamStruct FnCmdInRam = *(FnCmdInRamStruct *)(FnCmdInRam_); /* Create a copy of Wait in RAM routine on stack */

  ((pFnCmdInRam)&FnCmdInRam)();        /* Call code in RAM */

  return;

}

size of the code array is 12, but size of function FnCmdInRam_ is 14, crash in all flash operation.

10.4 with this issue, updated to 10.6 + update 1.0.0 and it remains.

need help.

thanks

Hi Bill,

I've created a project with the wizard including Processor Expert.

I've added the intFlash bean and enabled the SetByteflash and Getbyteflash function.

In the main.c file I've added the code:

/* Erase whole sector - necessary only if Write mode property is set to "Write" */

    Err = IFsh1_EraseSector(0xE000);

    /* Write number 28 to address 0xE000 */

    Err = IFsh1_SetByteFlash(0xE000, 28);

    /* Read contents of internal FLASH array on address

      0xE000 and write it to variable Data */

    Err = IFsh1_GetByteFlash(0xE000, &Data);

This is working fine on my board.

I see in the flash memory the value 1C at 0xE000.

I've disassembled the IFsh1.c file and got:

DISASSEMBLY OF: '.text' FROM 1036 TO 1905 SIZE 869 (0X365)

Opening source file 'F:/Temp_bis/Community/331964/MCU_10.6/test_pt60\Generated_Code\IFsh1.c'

  121: static void FnCmdInRam_(void)

FnCmdInRam_:

00000000 A680    LDA    #0x80

00000002 C70000  STA    NVM_FSTAT

  124:  while (NVM_FSTAT_CCIF == 0U) {}      /* Wait to command complete */

00000005 C60000  LDA    NVM_FSTAT

00000008 2AFB    BPL    *-3      ;abs = 0x0005

  126: }

0000000A 81      RTS  

the size of the function is 0xA =10.

Have a great day,

Hi Bill,

I don't have a PA60 but a TWR-S08PT60.

I will perform some tests on my side and will keep you informed.

Have a great day,
