Rewriting Code in Internal Flash

#1 Post by lordsant333 » 19 Apr 2021 11:44

Hi all,

Im using the stm32f439 and looking to find a way to write code in the internal flash. Is there a protected area for quality assurance and security? It's supposed to be used for company's intellectual property.
I would also like to know if there's a way to rewrite the system memory, I presume that it is the most protected area and couldn't find a way to write the code on it.

I would really appreciate any help,
Thanks!

Hi,

It would be best if you have a look at the memory specification of the stm32f439 MCU to have an insight how the memory is organized and accessed.
You can use compiler's Flash library to write to it, check the Flash library topic in the Help file and the supplied examples.

Regards,
Filip.
