Kinetis driver error kl c90tfs help me.

Hi I'm using the kl05 kinetis the TSS library and want to emulate the EEPROM using the c90tfs driver. When I call the function FSL_InitEeprom () generates an interrupt me of

PE_ISR (Cpu_ivINT_Hard_Fault)

{

/ * This code can be changed using the CPU component property "Build Options / Unhandled int code" * /

PE_DEBUGHALT ();

}

Specifically there is the interruption in the line 392 of the file "ee_high_level.c"

/ * If it is not first time initialization * /

/ * Check if the current field has been Identified active * /

if (EE_ERASED_STATE_32 == g_currentActiveSector)

{

/ * If the current active has not been Identified industry,

then the first turn before the alternative is the current active industry sectors * /

sectorAddress = PREV_SECTOR (altSectorAddress);

----> here --- >>> sectorStatus = READ32 (sectorAddress);

/ * The first turn before the alternative sector, the industries is the latest Active field * /

while (EE_SECTOR_STATUS_ACTIVE! = sectorStatus)

{

sectorAddress = PREV_SECTOR (sectorAddress);

sectorStatus = READ32 (sectorAddress);

}

g_currentActiveSector = sectorAddress;

g_freeSpaceAddress = sectorAddress + EE_SECTOR_SIZE - EE_SECTOR_WASTE;

}

my master code is as follows:

int main (void)

/ * lint-restore Enable MISRA rule (6.3) checking. * /

{

/ * Variable local Write your definition here * /

/ / Delay_ms (500) / / DELAY MANDATORY for stability

/ *** Processor Expert internal initialization. DO NOT REMOVE THIS CODE! *** /

PE_low_level_init ();

/ *** End of Processor Expert internal initialization. *** /

/ * Write your code here * /

/ * For example: for (;;) {} * /

UINT32 fnSize = 0x200;

UINT32 fnSrc = (UINT32) FSL_FlashCommandSequence - 1;

UINT32 fnDest = (UINT32) __ram_for_command_sequence_func;

CopyToRAM (fnDest, fnSize, fnSrc);

/ / Assign value to the global function pointer for FlashCommandSequence. / /

/ / The EED will use this pointer whenever service calls FlashCommandSequence it. / /

g_pFlashCommandSequence = (pFLASHCOMMANDSEQUENCE) (fnDest + 1);

returnCode = FSL_DeinitEeprom ();

if (EE_OK! = returnCode)

{

ErrorTrap ();

}

returnCode = FSL_InitEeprom () ;/ / FSL_DeinitEeprom ();

if (EE_OK! = returnCode) {ErrorTrap ();}

WaitEepromReady ();

Erase the whole chip and try again by disableinterrupts before calling initeeprom.

If error still happends, check whether sectorAddress is within the flash area. Reading of non-existing address will cause fault interrupt.
