Hi!

MSP430FR5969+MSP430FR5972 how to protect the embedded code-program?

CCS8 i use.

I want the program that I wrote down in the chip MSP430FR5972 could not be read,

but it was possible to rewrite the whole program (to load a new one instead of the old one)

and it was impossible to "plug in" someone else's additional code into the chip MSP430FR5972 to read my program.
How to do it ?

Hello Alexander,

If you haven't yet looked into the MSP430FR59xx family users guide, in section 9.2.2 it discusses the IP encapsulation segment.

Let us know if that is not what you are looking for.

Ok, IP is a 50% problem.

And that abaut this?

Atmel use "FLASH Lock bits" for this - "Programming and Verifacation disabled" and some "Fuse bits"

Hi Alexander,

Referring to the same user's guide as above, check out section 1.13 (JTAG and SBW Lock Mechanism using Electronic Fuse).
Using this feature you can prevent anyone from reading or writing memory using the JTAG or SBW interface.

Also check out the MSP code protection application note slaa685. It describes in detail how to implement the JTAG, IPE and BSL protection.

Thank you for your help!
I carefully read what you have recommended and figured out the issue of closing the code.
Once again, thank you very much!

Now I'm sure that I chose MSP430 for my main developments.
