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

BillQu — Sat, 04 Oct 2014 07:25:48 GMT

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

bill

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,

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,
