MSP430FR6989: MSP430FR6989 CMD file config

user6530276

Part Number: MSP430FR6989

I would like to split a few Spaces in the FRAM of 6989: Origin = 0x4400, Length = 0XBB80, which can be powered down to keep the data.

Try # pragma PERSISTENT (FRAM_DAC)

#pragma location = 0xC23e// address

uint16_t FRAM_DAC[6]={0};

Data cannot be written to this space.Now I want to configure the CMD file to implement it.How do I do that? Thanks!!

Hi,

You need to initialize the FRAM_DAC before you use it. Please refer to the fram_write code example.

uint16_t FRAM_DAC[6]={0}; This initializes FRAM_DAC to 0。

# pragma PERSISTENT (FRAM_DAC)

uint16_t FRAM_DAC[6]={0};

Just like that, you can use it without specifying an address
