MSP430FR2676: Regarding ROM area memory test

Hi Sasaki,

Why this customer need verfication this data in ROM.

As you know, this data is store in ROM in factory and can't write, thus  this should not be corrupted.

Is there are some issue for this area data?

Thanks!

The customers want to prevent the MSP430 from malfunctioning when the ROM data is corrupted. Therefore, they want to check if the ROM data is correct.

It is similar to functional safety.

Is there a way to check the ROM data?

Hi Johnson-san,

Thank you for the information.

I think it is possible to verify the data if ROM Lib can be written to FRAM.
Is there a ROM Lib CCS project? I want to use it to write ROM Lib to FRAM and verify the data.
