MSPM0G1507: Can data be written to the NONMAIN area?

Tool/software:

Hi All,

[Question 1]
We would like to store non-updated user data in the NONMAIN area.
By default, bootloader-related values are stored, but is it possible to store them without affecting these values?
If so, what is the memory address?

[Question 2]
I want to store frequently updated values in lower 32kB flash (0x0000 0000 ~ ).


How do I change the linker file in CCS?

Best Regards,

Ito

    For your first question, not recommend to do that, because for nonmain flash just one sector that means you need to erase all data when you want to erase the flash to save some data. 

    For the second question, you need to modify the cmd file in CCS to manage the memory. You can refer this as a demo
