MSPM0L1306: Writing to flash memory and reading from it to get the last data stored in flash to read from it after Power cycle.

Thank you Zaey,

I have used 

/* 32-bit write to flash in main memory */
DL_FlashCTL_unprotectSector(
FLASHCTL, MAIN_BASE_ADDRESS, DL_FLASHCTL_REGION_SELECT_MAIN);
gCmdStatus = DL_FlashCTL_programMemoryFromRAM32(
FLASHCTL, (MAIN_BASE_ADDRESS + 16), &gData32);
if (gCmdStatus != DL_FLASHCTL_COMMAND_STATUS_PASSED) {
/* If command did not pass, set error flag. */
gErrorType = ERROR_WRITE_32_BIT;
}

to write memory
and 
gData32Read = *(uint32_t *)(MAIN_BASE_ADDRESS);
to read from memory. 

But this read instruction puts device in Hardfault 

Thank you Joey,

I have gone through your code but when trying to read the code 
    gData32Read = *(uint32_t *)(MAIN_BASE_ADDRESS+16);

it is not working properly

it seems a little odd.

If you work with launchPad MSPM0L1306?

Yes working on launchPad MSPM0L1306

So if you try to read the code, it still run into default handler?

Here is the successful result of mine.

When you enter into default handler, can you look register CPUSS to find out which makes it into default handler?

Thanks

Thanks Joey,

but mine is not working it is not even writing on memory

Hi,

It seems your code flash is larger than 0x1000. 

Please try another larger address to write

Hi Joey,

Program Size: Code=8264 RO-data=572 RW-data=12 ZI-data=584  
This is size of my program and I have defined MAIN_BASE_ADDRESS as 0x00003000
Now it is not putting MCU in hardfault but if there is any flag and that one is 1 then also it is not going inside that if condition in main()

u can see that in following SS


in this condition is true still it is not going inside the function.
