Hi , I am developing in MSP430F5335 + CC2564 with IAR Bluetopia SPPLEDemo project.
I want to store some data into MSP430 and not be clear when MSP430 power off.
I reference the msp430f66xx_flashwrite_02.c , and use the following code:
unsigned long * Flash_ptrD;
Flash_ptrD = (unsigned long *) 0x1800; // Initialize Flash pointer
value = 0x1234; // Initialize Value
FCTL3 = FWKEY; // Clear Lock bit
FCTL1 = FWKEY+ERASE; // Set Erase bit
*Flash_ptrD = 0; // Dummy write to erase Flash seg
FCTL1 = FWKEY+BLKWRT; // Enable long-word write
*Flash_ptrD = value; // Write to Flash
FCTL1 = FWKEY; // Clear WRT bit
FCTL3 = FWKEY+LOCK; // Set LOCK bit
And then print the following:
Display(("Flash_ptrD = %x\r\n",Flash_ptrD));
Display(("Flash_ptrD = %x\r\n",*Flash_ptrD));
the result is
Flash_ptrD = 1800
Flash_ptrD = 1234
But when I turn off and turn on the device , and print the value again.
It show the following:
Flash_ptrD = 0
Flash_ptrD = d032
So...It seems the data did not store into memory. Did I missing something ?
How to store some data into MSP430 and not be clear when MSP430 power off ?
Thanks in advance.
