MSPM0L1306: MCU goes into Default Handler while writing in Flash Memory

Hi Rahul,

What FLASH address range are you attempting to write to?

Hello Sir,

I am trying to write at following address:

#define MAIN_BASE_ADDRESS (0x00001000)

The flow of code in my source code goes like this:

//Variables declared

uint8_t gData8 = 0x55;
unsigned char Test = 0;
unsigned char *pTest;

//Unprotect Flash
DL_FlashCTL_unprotectSector(FLASHCTL, MAIN_BASE_ADDRESS, DL_FLASHCTL_REGION_SELECT_MAIN);

//Write to Flash

gCmdStatus = DL_FlashCTL_programMemoryFromRAM8(FLASHCTL, MAIN_BASE_ADDRESS, &gData8);

(Note here we get PASSED in gCmdStatus and sometimes the program goes in default handler here)

//Read_Verify flash

gCmdStatus = DL_FlashCTL_readVerifyFromRAM8(FLASHCTL, MAIN_BASE_ADDRESS, &gData8);

(Even when write function is passed this function always outputs FAILS)

pTest = (void *)(MAIN_BASE_ADDRESS+8);
Test = *pTest;

(Test variable don't get the same value as gData8)

Thanks and Regards.

Alright, thanks Dennis for your support.

Hi Rahul,

Are you able to get this working for you?

Hi Dennis, 

Actually we are working on this project on a really urgent notice so I didn't got a chance to retry flash access again, we found another way to implement our objective without using flash. I will let you know if we get to it again.

Thanks and Regards.
