Processor Expert and erasing flash

Hi all,

I'm using Processor Expert with CW 10.4 on a MCF51QU32VFM (coldfire+). I'm trying to write data to the internal flash. I've inserted a flash component using Processor Expert and defined a 1KB flash space at 0x200000 (where the DFlash starts). I copied the functions from the demo projects packaged with CW to erase, read and write to the flash. The following events methods have been defined in Events.c:

void FLASH1_OnOperationComplete(LDD_TUserData *UserDataPtr)

{

uint8_t *OpStatus = (LDD_TUserData*) UserDataPtr;

*OpStatus = TRUE;

}

void FLASH1_OnError(LDD_TUserData *UserDataPtr)

{

}

In my main function I first try to erase the 1KB of flash by calling the following function:

bool EraseFlash(LDD_TDeviceData *DeviceData, LDD_FLASH_TAddress FromAddress, LDD_FLASH_TDataSize Size, uint8_t* OpStatus)

{

LDD_TError Error;

int i = 0;

*OpStatus = FALSE;

Error = FLASH1_Erase(DeviceData, FromAddress, Size);

if (Error) {

return FALSE;

}

while(*OpStatus != TRUE);

return TRUE;

}

When FLASH1_Erase(..) is called in the above function, the FLASH1_OnError(..) event is triggered although FLASH1_Erase(..) returns with no error. FLASH1_OnOperationComplete(.. ) is never triggered, so EraseFlash(..) is stuck in an infinite loop at while(*OpStatus != TRUE).

Any help will be appreciated.

Thanks

Philip
