Erasing Flash sectors in KL25 and FreeRtos

HeronBR — Mon, 04 Mar 2013 12:01:32 GMT

I implemented successfully flash Erase and write routines as suggested in thread Erasing Flash sectors in KL25 on the Freedom Board, but when I tried to use with FreerRtos and more threads I got a message "No source available for "0xFFFFFFFE (0xFFFFFFFE)() ".

I already tried to use Cpu_DisableInt(); and taskENTER_CRITICAL(); but it didn't work. The error occurs after a few hundreds cycles.

Erase sector

FLASH1_Erase(FLASH1Pointer, 0x1F000, 1024);

do {

FLASH1_Main(FLASH1Pointer);

OpStatus = FLASH1_GetOperationStatus(FLASH1Pointer);

} while (!((OpStatus == LDD_FLASH_IDLE) | (OpStatus == LDD_FLASH_FAILED)));

And then write the data in Flash:

FLASH1_Write(FLASH1Pointer, FromPtr, 0x1F000, Size);

do {

FLASH1_Main(FLASH1Pointer);

OpStatus = FLASH1_GetOperationStatus(FLASH1Pointer);

} while (!((OpStatus == LDD_FLASH_IDLE) | (OpStatus == LDD_FLASH_FAILED)));

Does someone have any suggestion ?

Hi Heron,

We don't have much experience in FreeRTOS but you might be missing something in your flash driver. You could use the MQX FlashX driver as a reference and compare what it does is the same you are doing in your FreeRTOS Flash driver. My two cents :smileywink:!

Hope this helps you.
