MSP430FR6970: FRAM write

How do you want to program?

1. Do you accept to change the .hex file and program it? It would be the easist way.

2.  Another solution would be first you program the hex file. Then you program the wanted code without erasing other code.

3. Another solution is to send what you want to program through UART/I2C, let the software do the program by itself.

1. Yes i m ok for changing the hex file, but not source code.

2. OK. ok fine.

3. I'm not usinf any bootloader for this, im downloading the program directly by MSP-FET debugger.

I need some, external script to change some portion of FRAM by modifying the hex file.

The easilest way is to choose solution 2. 

Use Uniflash as an example, you can realise it by change the erase setting.

i want to write some data in hex file (inside fram location)

If so, I think you can create a script to do this. For example, python. It is easy, but it means you need to do some coding.

Yes, i need examples of python scripting and how to integrate, script with CC studio linker.

You don't need to handle the CCS linker.

You only need to handle the TI-TXT program file. Follow the style to add your customized code. 

For this, we don't have a related example. If you still want one, you can refer to https://www.ti.com/tool/download/MSPFRBOOT. At least, it will show you how to read all the download code.
