CCS/MSP430F5342: MSP430f5342

Hello samatha,

Are you using Driverlib for the MSP430F5xxx devices? The Driverlib has functions that you can use to write to particular segments of the flash. You can find it underneath "software" on the device's webpage.

See code and attached screenshot below, I created 4 arrays with corresponding data and wrote to each one separately without affecting the others.

#pragma LOCATION(array_8, 0x1900); //Specify array locations
#pragma LOCATION(array_8_2, 0x190a);
#pragma LOCATION(array_16, 0x1914);
#pragma LOCATION(array_32, 0x1928);

uint8_t array_8[10] = {}; //Define arrays
uint8_t array_8_2[10] = {};
uint16_t array_16[10] = {};
uint32_t array_32[10] = {};

uint8_t data_8[5] = {1,2,3,4,5}; //Data
uint16_t data_16[5] = {1,2,3,4,5};
uint32_t data_32[5] = {1,2,3,4,5};

uint8_t *segBstart = &array_8[0]; //Segment B starts

int main(void)
{

WDTCTL = WDTPW | WDTHOLD; // stop watchdog timer

FlashCtl_eraseSegment(segBstart); //Erase segment B

FlashCtl_write8(&data_8[0], &array_8[0], 5); //Write first array

FlashCtl_write8(&data_8[0], &array_8_2[0], 5); //Write second array

FlashCtl_write16(&data_16[0], &array_16[0], 5); //Write third array

FlashCtl_write32(&data_32[0], &array_32[0], 5); //Write fourth array

return 0;

}

All the best,
