FLASH COMPONENT CAN NOT MAKE UPDATES

Hi,

I am using CW10.7 and trying selected flash memory update in with the new parameters, however it is not allowing me second and another time after first downloading the code. I am using MKL25Z64VHL4 chip.

I am trying to erase or write into user sector FC00 to able erase 1024 bytes but the unit stil staying in ERR_BUSY instead of Flash Idle because DeviceDataPrv->CurrentOperationStatus = 24.

Is this problem to access to memory address?

#define SETTINGS_FLASH_ADDR 0xFC00 /* Reserve memory for settings flash memory location the data will be written to */
#define ERASE_FLASH_SIZE 0X0400 // minimum size section to ERASE
// Save Data
void SaveData(void)
{

Error = FLASH1_Erase(DeviceDataPtr, SETTINGS_FLASH_ADDR, ERASE_FLASH_SIZE);

do // CHECK OPERATION STATUS
{
FLASH1_Main(MyFLASH_Ptr);
OpStatus = FLASH1_GetOperationStatus(MyFLASH_Ptr);
} while (!((OpStatus == LDD_FLASH_IDLE) | (OpStatus == LDD_FLASH_FAILED)));

DataWrittenFlg = FALSE;

if (OpStatus == LDD_FLASH_FAILED)
{ /* Check if the operation has successfully ended */
/* Error state solution */
UError = ERR_ERASE_FLASH_FAILED;
}

DisplayError();

......

}

Thank you for assistance.

Regards,

Marceli

I have solved myself the problem using Demo FLASH example program. With small necessary changes to routines for checking OpStatus on the end:

bool WriteFlash(LDD_TDeviceData *DeviceData, LDD_TData* DataPtr, LDD_FLASH_TAddress FromAddress, LDD_FLASH_TDataSize Size, uint8_t* OpStatus)
{
*OpStatus = FALSE;
Error = FLASH1_Write(DeviceData, DataPtr, FromAddress, Size);
if (Error) {
return FALSE;
}
*OpStatus = FLASH1_GetOperationStatus(DeviceData);
while(*OpStatus != LDD_FLASH_IDLE); /* Wait while operation done */
return TRUE;
}

bool EraseFlash(LDD_TDeviceData *DeviceData, LDD_FLASH_TAddress FromAddress, LDD_FLASH_TDataSize Size, uint8_t* OpStatus)
{
*OpStatus = FALSE;
Error = FLASH1_Erase(DeviceData, FromAddress, Size);
if (Error) {
return FALSE;
}
*OpStatus = FLASH1_GetOperationStatus(DeviceData);
while(*OpStatus != LDD_FLASH_IDLE); /* Wait while operation done */
return TRUE;
}
