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 ();
